However, most theories assume that there is a general redistribution of information across the brain from encoding to consolidation. Continuation of BIOL 319. 3. program is recommended for students who intend to pursue further education in completion of requirements for teacher certification. II, BIOL 344 Embryology (Credits 4. High levels of organic chemicals accumulate in these animals since they are near the top of food chains and have large reserves of blubber. This position creates a change of water flow pattern from the infant which minimizes separation between the mother and infant, but also increases the mother's surface area and creates a drag for the swimmer. 3. The active hemisphere handles surfacing and breathing behavior. FAO Animal Production and Health Guidelines. Calculate statistically meaningful summaries of the measurements made in the lab Link the key concepts in bacterial metabolism to virulence 1. Several different corvids, particularly ravens, have occasionally served as pets, although they are not able to speak as readily as parrots, and are not suited to a caged environment. [178] There has been some debate over the cause of the decline of Steller sea lions in Alaska since the 1970s. II, 335. For information on past, current, or future course offerings, check theHowdy! 2. 10. Each animal has a uniquely identifying, frequency-modulated narrow-band signature vocalization (signature whistle). [22] They also hunt alone, often targeting bottom-dwelling species. Male pinniped strategies for reproductive success vary between defending females, defending territories that attract females and performing ritual displays or lek mating. Compare and contrast different antimicrobial control mechanisms CS1 maint: multiple names: authors list (, cryoconservation of animal genetic resources, Learn how and when to remove this template message, Cryoconservation of animal genetic resources, "IUCN Species Survival Commission Guidelines on the Use of Ex situ Management for Species Conservation". 3. Corvid ingenuity is represented through their feeding skills, memorization abilities, use of tools, and group behaviour. [9] The high occurrence of genetic disorders within a captive population can threaten both the survival of the captive population and its eventual reintroduction back into the wild. (1987) "The social structure of free-ranging bottlenose dolphins", pp. However, Steller's jays, which are successful independently of human development, are more efficient in plundering small birds' nests than American crows and common ravens. 3. 6. Explain/sketch mechanisms by which gene expression may be regulated at levels of transcription, RNA processing, translation, and protein turnover in eukaryotic cells, Learning outcomes, be able to: 7. Behavioral Adaptations for Sharks Hunting/Feeding. 9. [44] Bottlenose dolphins typically swim at 5 to 11km/h (1.4 to 3.1m/s), but are capable of bursts of up to 29 to 35km/h (8.1 to 9.7m/s). 496 Ethics in Biological Research. Niche The G.W shark is found in temeprate and sub tropical habitats. Predict the outcomes and/or constraints for membrane transport processes Texas high schools are in need of qualified teachers in math and science. 3. 4. [35] The corneal epithelium is keratinized and the sclera is thick enough to withstand the pressures of diving. Sketch/explain the processes of DNA replication, repair, and recombination [46] Ice-living seals like the harp seal have corneas that can tolerate high levels of ultraviolet radiation typical of bright, snowy environments. 7. There is no larval stage. [84] New Zealand sea lions are the only pinnipeds that can be found up to 2 kilometres (1.2mi) inland in forests. Seals range in size from the 1m (3ft 3in) and 45kg (99lb) Baikal seal to the 5m (16ft) and 3,200kg (7,100lb) southern elephant seal male, which is also the largest member of the order Carnivora. aduncus. 3. 8. [4], When first learning a motor task, movement is often slow, stiff and easily disrupted without attention. It is illegal to own corvids, or any other migratory bird, without a permit in North America, due to the Migratory Bird Act. 6. 10. Hunting habits of three species are summarized below: the white (Carcharodon carcharias), tiger (Galeocerdo cuvier), and bull (Carcharhinus leucas) sharks. Use phylogenetic tools to understand patterns in species diversity. Define phylogeny Labs include study of preserved material and demonstration of living animals in aquaria and terraria. WebSpecies reintroduction is the deliberate release of a species into the wild, from captivity or other areas where the organism is capable of survival. [7] Pinnipeds belong to the order Carnivora and the suborder Caniformia (known as dog-like carnivorans). [14] Strength training results are seen in the spinal cord well before any physiological muscular adaptation is established through muscle hypertrophy or atrophy. Some corvids are well-known communal roosters. [74], The main adaptations of the pinniped circulatory system for diving are the enlargement and increased complexity of veins to increase their capacity. Explain the role of ecology in predicting the distribution and abundance of populations in the biosphere. The Baikal seal is the only exclusively freshwater species. When participating in any sport, new motor skills and movement combinations are frequently being used and repeated. Increased body weight in males increases the length of time they can fast due to the ample energy reserves stored in the blubber. The core courses for this degree will include a foundation in the life sciences, and a foundational sequence in neuroscience that will prepare students for more advanced courses. Both sexes are about the same size at birth, but mature males are typically 30% to 50% longer and three times as massive as females. In ecology, the population Identify major muscles (and respective AOIs) of the human body using human models and cat dissection specimens. Demonstrate proper use of grammar and writing skills including the ability to professionally use digital communication 2. 2. However, Herman, Richards, and Wolz demonstrated comprehension of an artificial language by two bottlenose dolphins (named Akeakamai and Phoenix) in the period of skepticism toward animal language following Herbert Terrace's critique. Females tended to wean mid-pregnancy. 9. This happens only during low tides. [35] Somehow there is a distinct process within the brain related to writing letters, which is dissociated from copying and drawing letter-like items. [50], By contrast, a bottlenose's sense of smell is poor,[51] because its blowhole, the analog to the nose, is closed when underwater and it opens only for breathing. 7. The dolphin became infamous for killing a swimmer and injuring many others, which later earned him the nickname "Killer Dolphin". Pinnipeds also have very muscular and vascularized irises. The Global Plan of Action for Animal Genetic Resources and the Interlaken Declaration. Hybrids with Risso's dolphin occur both in the wild and in captivity. 6. 4. Zalophus, Eumetopias and Otaria diverged next, with the latter colonizing the coast of South America. Describe the roles of membrane transport in cellular function and homeostasis Describe the ocean current regimes of the Americas with special reference to the Gulf of Mexico Explain how genetic variation (SNPs) data are used to study populations and to uncover the basis of disease Prey animals may appear as predators, or vice versa; both predators and prey may be hard to see (), or may be [105], The mating system of pinnipeds varies from extreme polygyny to serial monogamy. Prerequisites: BIOL 213 and 214; junior or senior classification. 1. Grass-wearing behavior among these dolphins is a local behavioral tradition that could constitute a cultural difference from other communities. I, II, 413. 5. Some species also rest on man-made structures, like piers, jetties, buoys and oil platforms. Describe the enormous diversity among the annelids, mollusks and arthropods, and give reasons for their success in so many habitats 9. Classification, phylogeny, comparative anatomy and biology of chordates; diversity, protochordates, vertebrate skeletons, shark and cat anatomy studied in laboratory. [163], Pinnipeds can be found in facilities around the world, as their large size and playfulness make them popular attractions. 7. 7. 3. One of the first signs that West Nile virus first arrived in the US in 1999 was the death of crows in New York.[70]. WebThe adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. Crows have been known to attack dogs, cats, ravens, and birds of prey. [151] Female elephant seals make an unpulsed attraction call when responding to their young. Explain how animal diversity is the result of evolution Ex situ management can occur within or outside a species' natural geographic range. The individual hairs on the coat, known collectively as lanugo, can trap heat from sunlight and keep the pup warm. 3. Pinnipeds belong to the order Carnivora; their closest living relatives are musteloids (weasels, raccoons, skunks, and red pandas), having diverged about 50million years ago. I, II, 492 Biomedical Therapeutics Development. May be repeated once for credit. Seedbanks are ineffective for certain plant genera with recalcitrant seeds that do not remain fertile for long periods of time. Demonstrate how to use commercial and open source software to address image acquisition, processing and analysis The first two years of any major in biology is quite similar. Principles of Evolution. They also lack supraorbital processes on the frontal and have underdeveloped calcaneal tubers. Problems in various phases of plant, animal and bacteriological science. Explain the basic approaches to making transgenic plants, animals, fungi, and bacteria Explain how economic factors influence antibiotic development, Study Abroad, email Dr. Leslie Winemiller [email protected].

Discuss the main elements of and distinctions between innate and adaptive immunity 4. Survey of animal life with respect to cell organization, genetics, evolution, diversity of invertebrates/vertebrates, anatomy/physiology, and interaction of animals with their environment; course includes laboratory that reinforces and provides supplemental information related to lecture topics. Prerequisites, be able to: The presumed corvid relatives included: currawongs, birds of paradise, whipbirds, quail-thrushes, whistlers, monarch flycatchers and drongos, shrikes, vireos, and vangas,[2] but current research favors the theory that this grouping is partly artificial. Zoology deals with all aspects of the study of animals from physiology and anatomy to ecology and systematics. Discuss the mechanisms of cell mediated immunity the T lymphocyte response Seals produce a number of vocalizations, notably the barks of California sea lions, the gong-like calls of walruses and the complex songs of Weddell seals. Sharks use the senses of smell (chemoreception), vision, hearing, the lateral line system, and electroreception (ampullae of Lorenzini) for capturing prey. [188][189][187], Seals also conflict with fisherman. Describe adaptation-based hypotheses for the evolution of sex [85][86], Pinnipeds can produce a number of vocalizations such as barks, grunts, rasps, rattles, growls, creaks, warbles, trills, chirps, chugs, clicks and whistles. 3. Explain in quantitative terms how allele and/or genotypic frequencies are affected by gene flow, natural selection, genetic drift, mutation, recombination, and non-random mating Critically analyze scientific research presentations through questioning and discussions. 1. The deep split between the lineages of Erignathus and Cystophora 17mya suggests that the phocines migrated eastward and northward from the North Atlantic. Seals are more agile and flexible,[35] and some otariids, such as the California sea lion, are capable of bending their necks backwards far enough to reach their hind-flippers, allowing them to make dorsal turns. [76], Along the beaches and tidal marshes of South Carolina and Georgia in the United States, bottlenose dolphins cooperatively herd prey fish onto steep and sandy banks in a practice known as "strand feeding". This enables them to chase down prey that would otherwise be able to outrun them. Males have large testes in relation to their body size. Brain areas active during motor learning include the motor and somatosensory cortices; however, these areas of activation decrease once the motor skill is learned. [81], Pinnipeds may hunt solitarily or cooperatively. [12] Preventing certain individuals from the breeding also reduces the effective population size, which is associated with problems such as the loss of genetic diversity and increased inbreeding.[10]. If you were admitted to Texas A&M for a BS in Molecular & Cell Biology prior to Fall 2022 please, This Degree plan applies to students beginning in Fall 2022 or later. Explain the differences between prokaryotes and eukaryotes, protists and Animalia 3. Define the mechanisms that viruses use to overcome the host immune response Demonstrate a basic understanding of the chemical basis of life Outline how antibodies can be used therapeutically and as tools in research, Learning outcomes, be able to: [17] The fossil monachine Monotherium and phocine Leptophoca were found in southeastern North America. They are commonly kept in captivity and are even sometimes trained to perform tricks and tasks. It is to be used as a last resort, or as a supplement to in situ conservation because it cannot recreate the habitat as a whole: the entire genetic variation of a species, its symbiotic counterparts, or those elements which, over time, might help a species adapt to its changing surroundings. Prerequisites, be able to: Their mystacial vibrissae have ten times the innervation of terrestrial mammals, allowing them to effectively detect vibrations in the water. WebDeception in animals is the transmission of misinformation by one animal to another, of the same or different species, in a way that propagates beliefs that are not true.. Mimicry and camouflage enable animals to appear to be other than they are. These animals lack external ear flaps and are incapable of turning their hind-flippers forward, which makes them more cumbersome on land. 11. I, II, S. 388. [23] Repetitive behaviors, such as typing on a computer from a young age, can enhance such abilities. Youngsters of social corvid species undergo a series of tests, including aerobatic feats, before being accepted as a mate by the opposite sex. In some phocid species, like the harbor seal, Weddell seal and bearded seal, the males have underwater territories called "maritories" near female haul-out areas. Later, in western literature, popularized by American poet Edgar Allan Poe's work "The Raven", the common raven becomes a symbol of the main character's descent into madness. 5. Compare and contrast prokaryotic and eukaryotic cells in terms of size, organization, function of subcellular structures, and relationships to multicellular functions 10. Describe the following basic analytical techniques in biochemical and molecular biology: spectrophotometry, SDS-PAGE, Western blots, PCR, subcellular fractionation, enzyme kinetics, DNA sequencing The sequel was released on September 12, 2014. 1. 10. As a whole, pinnipeds can be found in a variety of aquatic habitats, including coastal water, open ocean, brackish water and even freshwater lakes and rivers. [41] The animal propels itself by moving the flukes up and down. The only unique [] 6. [54] Marc Bekoff, at the University of Colorado, argues that it shows that they are capable of feeling complex emotions, including grief. Compare and contrast how different endomembranes and cytoskeletal activities in different parts of the cell cycle produce different outcomes 3. The position of the azure-winged magpie, which has always been of undistinguished lineage, is less clear than previously thought. [142] Otariid females and their young use mother-pup attraction calls to help them reunite when the mother returns from foraging at sea. For example, in the town of Laguna in south Brazil, a pod of bottlenose dolphins resides in the estuary, and some of its members cooperate with humans. [43] Fore-flipper movement is not continuous, and the animal glides between each stroke. Prerequisites, be able to: [17] Otariids originated in the North Pacific. [100], Seals typically consume their prey underwater where it is swallowed whole. Once relentlessly hunted by commercial industries for their products, seals and walruses are now protected by international law. 8. Some coastal shark species can survive in brackish estuaries with mixed fresh- and saltwater. Prerequisite: BIOL 413 or concurrent enrollment or approval of instructor. Explain how adaptations to different environmental conditions relate to survival, reproduction, and broad patterns of species diversity whether it be maintaining proper form when paddling a canoe, sitting with a neutral posture, or bench pressing a heavier weight. In the United States, pinnipeds are protected under the Marine Mammal Protection Act of 1972 (MMPA). Animal welfare activists and certain scientists have claimed that the dolphins do not have adequate space or receive adequate care or stimulation. Essentials in Biology (3-3). Selected topics in an identified area of biology. Define the following ecological terms: habitat, niche, competition, parasitism, symbiosis, disturbance, succession, geographic speciation, Learning outcomes, be able to: Directed Studies.

Prerequisite: BIOL 214 or approval of instructor. Explain antigen- antibody interaction outcomes based on antigen structure Computing Help Describe Evolution as a science and philosophy 9. The nutcrackers were more accurate in their searches than the jackdaws and pigeons. [172] Several species that were commercially exploited have rebounded in numbers; for example, Antarctic fur seals may be as numerous as they were prior to harvesting. Demonstrate proficiency in college level arithmetic [95], Pinnipeds have lifespans averaging 2530years. [41], Interspecific communications are evolutionarily beneficial for species living in the same environment. 7. 7. The basihyal is a small, thick piece of cartilage located on the floor of the mouth of sharks and other fishes. This is thought to reflect the musician's innate ability, which may be fostered by an early exposure to musical training. Explain regulation of stem cells and progenitors But attempting to learn two such patterns one immediately after the other could cause the first one to be forgotten. It is important to manage captive populations in a way that minimizes these issues so that the individuals to be introduced will resemble the original founders as closely as possible, which will increase the chances of successful reintroductions. When a pod finds a school of fish, they will circle the school and trap the fish in a mini whirlpool. Discuss the main elements of and distinctions between innate and adaptive immunity including timing, adaptability, and memory capabilities [57], The tonal whistle sounds (the most melodious ones) allow dolphins to stay in contact with each other (above all, mothers and offspring), and to coordinate hunting strategies. (2010). 9. 4. Describe the molecular components and mechanisms of cellular signal transduction WebLecture and field study of adaptations of vertebrate classes for survival in particular environments. Recognize the contributions of Charles Darwin to the science of evolution in Biology is designed so that students obtain a comprehensive, solid foundation in the branches of biology combined with a suitable measure of individual flexibility. Our history is inextricably intertwined with the seashore, being a rich tapestry of archaeological sites that paint a vivid picture of people hunting, foraging, fishing and scavenging at the edge of the sea. WebThe main adaptations of the pinniped circulatory system for diving are the enlargement and increased complexity of veins to increase their capacity. In many parts of Britain, gatherings of crows, or more often magpies, are counted using the divination rhyme: one for sorrow, two for joy, three for a girl, four for a boy, five for silver, six for gold, seven for a secret never to be told. Another rhyme is: one for sorrow, two for mirth, three for a funeral, four for a birth, five for heaven, six for hell, and seven for the Devil, his own sel. Cornish superstition holds that when a lone magpie is encountered, it must be loudly greeted with respect. Explain the structures and functions of plant and animal organ systems, Learning outcomes, be able to: 6. [25] An example of this is bimanual synchronized finger movements, which play an essential role in piano playing. Prerequisites, be able to: This distinction is being questioned as indigenous people are using more modern weaponry and mechanized transport to hunt with, and are selling seal products in the marketplace. A recent issue in motor memory is whether or not it consolidates in a manner similar to declarative memory, a process that involves an initial fragile learning period that eventually becomes stable and less susceptible to damage over time. Define and give examples of natural selection, stabilizing selection, genetic drift, random mating, genetic bottleneck, homology, phylogeny 1. Sketch/explain the physical nature of a gene and mechanisms for regulating gene expression 7. Plants under horticultural care in a constructed landscape, typically a botanic garden or arboreta. 2. Newborn bottlenose dolphins are 0.8 to 1.4m (2.6 to 4.6ft) long and weigh 9 to 30kg (20 to 66lb), with Indo-Pacific bottlenose dolphin infants being generally smaller than common bottlenose dolphin infants. Dominant male elephant seals advertise their status and threaten rivals with "clap-threats" and loud drum-like calls[143] that may be modified by the proboscis. This allows for the proliferation of clonal plants from a relatively small amount of parent tissue. The embryos are nourished by a yolk-sac inside the egg capsule. Elephant seals stay at sea 810months a year and migrate between breeding and molting sites. I, II, S, 112. The flap is closed during muscle relaxation and opens during contraction. Weaver, A., & Kuczaj, S. (2016). [11] There are 34 extant species of pinnipeds,[4] and more than 50 fossil species. Explain how the neural control of kidney water conservation is responsive to changing osmotic environments 4. Its color varies considerably, is usually dark gray on the back and lighter gray on the flanks, but it can be bluish-grey, brownish-grey, or even nearly black, and is often darker on the back from the rostrum to behind the dorsal fin. The known prehistoric corvid genera appear to be mainly of the New World and Old World jay and Holarctic magpie lineages: In addition, there are numerous fossil species of extant genera since the MioPliocene, mainly European Corvus.[a]. In addition to foraging, vibrissae may also play a role in navigation; spotted seals appear to use them to detect breathing holes in the ice. Credit 1. [31], Bottlenose dolphins appeared during the Miocene. 1. 9. [8], Captive populations are subject to problems such as inbreeding depression, loss of genetic diversity and adaptations to captivity. Analyze and interpret microbiology-related experimental data. Like other marine mammals, seals sleep in water with half of their brain awake so that they can detect and escape from predators. 4. Plants are under horticulture care, but the environment is managed to near natural conditions. In air, hearing is somewhat reduced in pinnipeds compared to many terrestrial mammals. Bacterial Physiology (Credits 3. They further suggested that the high intelligence of the crows enables them to adapt well to human-dominated environments. However, within the motor cortex, endurance induces angiogenesis within as little as three weeks to increase blood flow to the involved regions. Reading scientific papers and writing short synopses of papers with a focus on learning how to think and write like a scientist; fills one of the current Writing Intensive W course requirements for biology. The male can retract and conceal his penis through his slit. The area of a sexual population is the area where inter-breeding is possible between any pair within the area and more probable than cross-breeding with individuals from other areas.. Credit 3. 2. 1. 15. Registration in multiple sections of this course is possible within a given semester provided that the per semester credit hour limit is not exceeded. Typically species that are either difficult or impossible to conserve in seed banks are conserved in field gene banks. In Shark Bay, off Western Australia, dolphins place a marine sponge on their rostrum, presumably to protect it when searching for food on the sandy sea bottom. Migration. This includes: acoustic and behavioral mimicry,[60][61] comprehension of novel sequences in an artificial language,[62][63] memory,[64] monitoring of self behavior,[65] discrimination and matching,[64][66] comprehension of symbols for various body parts,[67] comprehension of pointing gestures and gaze (as made by dolphins or humans),[68][69] mirror self-recognition,[70][71] and numerical values. Diagram DNA replication, transcription, and translation indicating the players involved in each Describe gene silencing in plants and animals (VIGS, RNAi) 6. Sketch a branching phylogeny (cladogram) describing how morphological characters are used to distinguish the major classes of chordates Hebb's rule states that "synaptic connectivity changes as a function of repetitive firing." [17], Odobenidae consists of only one living member: the modern walrus. A seagoing "Lassie", Flipper understood English and was a hero: "Go tell Dad we're in trouble, Flipper! [13], Muscle memory consolidation involves the continuous evolution of neural processes after practicing a task has stopped. Explain how cytoskeletal dynamics contribute to cell structure, organization, and directed movement Identify tissues and relate their structure to their physiology Shark species that utilize this mode of reproduction include the swell shark, dogfish, and angel sharks. This "rhythmic entrainment" was previously seen only in humans, parrots and other birds possessing vocal mimicry. 7. Introductory Biology II (3-3) Credit 4. Explain the molecular/cellular mechanisms responsible for the onset of cancer and metastasis. 3. Perform genome analyses using Galaxy 1. 6. [77] While initially documented in South Carolina and Georgia, strand feeding has also been observed in Louisiana, Texas, Baja California, Ecuador, and Australia. 15. [14] Compared to other carnivorans, their teeth tend to be fewer in number (especially incisors and back molars), are pointed and cone-shaped, and lack carnassials. However, upon secondary exposure to resistance exercise, a greater frequency of hypomethylated CpG sites was observed, where over 18,000 sites reported as being significantly hypomethylated. Describe the key events in the history of life on Earth, including the origins of photosynthesis, eukaryotic cells, and multicellularity Describe how membrane potentials are created and maintained 2. [12], Otariids are also known as eared seals due to the presence of pinnae. Identify the key targets and mechanisms of antimicrobials in treating infectious disease Integrative Animal Behavior. This patient was diagnosed with a pure form of dysgraphia of letters, meaning he had no other speech or reading impairments. Francis Galton noted in his landmark paper on domestication that seals were a spectacular example of an animal that would most likely never be domesticated despite their friendliness and desire for comfort due to the fact that they serve no practical use for humans. Hence polygyny tends to be weaker in ice-breeding species. Demonstrate ability to measure environmental parameters using scientific data collection equipment Explain how the information in genes flows from DNA to proteins through the processes of transcription and translation and how these processes can be regulated [73] The middle ear contains sinuses that probably fill with blood during dives, preventing middle ear squeeze. 10. Molecular studies show the genus definitively contains two species: the common bottlenose dolphin (Tursiops truncatus) and the Indo-Pacific bottlenose dolphin (Tursiops aduncus). [79][80] Similar cases have been observed in Laguna, Santa Catarina in Brazil since during 19th century as well. A 2005 study showed mothers most likely teach the behavior to their offspring, evincing culture (behavior learned from other species members). [89] Ringed seals build dens underneath fast ice. 9. 5. Calculate allele frequencies in a population Explain/sketch mechanisms by which gene expression may be regulated at levels of transcription, RNA processing, translation, and protein turnover in eukaryotic cells 5. [30] Corvids and psittacids have higher EQ than other bird families, similar to that of the apes. 4. [10] In large, outbreeding populations, the frequencies of most deleterious alleles are relatively low, but when a population undergoes a bottleneck during the founding of a captive population, previously rare alleles may survive and increase in number. Sketch/explain the physical nature of a gene and mechanisms for regulating gene expression [5] Research suggests we do not start off with a blank slate with regard to motor memory although we do learn most of our motor memory repertoire during our lifetime. Male sharks have paired intromittent organs called claspers. Prerequisites, be able to: [33][34][35] By remaining with the parents, the young have more opportunities to learn necessary skills. Explain what constitutes plagiarism The lateral line system, which all fishes possess, allows them to detect waves of pressure or mechanical disturbances in the water. In 1972, the U.S government passed a law limiting the number of dolphins that could be killed yearly by tuna fishing crews. Restricted to senior undergraduate majors in biology, microbiology, botany or zoology. In the late 1970s and throughout the 1980s, Sibley and Ahlquist united the corvids with other taxa in the Corvida, based on DNADNA hybridization. [127] Similar behaviour has been observed in Ireland. Explain the relationship between cell adhesion and tissue development/function [3] Others, like the Burrunan dolphin (Tursiops (aduncus) australis), may be alternately considered their own species or be subspecies of T. 350. [81][82] Only monk seals live in waters that are not typically cool or rich in nutrients. May not be used for credit by biology, molecular and cell biology, microbiology, zoology, predentistry or premedicine majors. In the mid-nineteenth century, the species was thought to have gone extinct until a small colony was found near the Yucatn Peninsula in 1886. Compare and contrast how microbial enzymes, toxins, adhesion factors, and antiphagocytic factors affect virulence Describe the role of genes in determining the form and function of animals, and explain the process of inheritance by calculating probabilities of offspring resulting from parental crosses Pinnipeds have well-developed sensestheir eyesight and hearing are adapted for both air and water, and they have an advanced tactile system in their whiskers or vibrissae. Biology of Viruses (3-0). Describe the structure and function of the unique water-vascular system of echinoderms [107] Arctic seals use more breathing holes per individual, appear more restless when hauled out, and rarely defecate on the ice. When relying more on the sense of hearing, smell, or their lateral line, they can more easily mistake human activity in the water as that of their prey which is mostly comprised of schooling fishes. 2. In science, it is also sometimes restricted to the "true" seals of the family Phocidae. 7. 11. 2. Not to be confused with, Consciousness, culture-rudiments, and neurology, Tool use, memory, and complex rational thought, Implications and specific comparisons with other animals.
