1. How is linkage equilibrium similar to Hardy-Weinberg equilibrium and why? (5) 2. What does Muller’s Ratchet predict and why does it occur? How does sexual reproduction break the ratchet? (5) 3. What is the difference between directional selection and stabilizing selection? How will each model of selection, in theory, affect overall variation in the population? (5) 4. A population of fish have a mean body length of 15 centimeters. A new predator is introduced into the system that preys on all but the largest fish. The mean length of the surviving fish is 27 centimeters long. If in the following generation the mean length of the survivors offspring is 24 centimeters long, what is the narrow-sense heritability of body length? (5)

6. A) What is a coelom? Why was its evolution important to multicellular animals? B) Describe all the basic characteristics of the Mollusca (e.g., why are they classified as lophotrochozoan protostomes?). C) Define the following: periostracum, prismatic layer, nacreous layer, reduced coelom, muscular foot, mantle, gills and their functions. D) Outline the main characteristics of the following groups: Bivalvia, Gastropoda, and Cephalopoda. E) Do our eyes show a high degree of morphological convergences with those of the cuttlefish Sepia? Explain. How can morphological convergence such as eye convergence happen? F) Is there any embryological evidence that the Mollusca share a common ancestor with those of polychaete annelids? If so, what is the evidence? G) Define the following: trochophore larva, dioecious, radula, siphuncle, hectocotylus arms, tentacles.

Biology Assignment Writing ServiceQuestion: You decide to use SDS-PAGE to check the purity of your protein after a purification step. You have few contaminants, but the band on the gel that you believe to be your target protein is seen at a higher molecular weight than you have expected. Why think this would be ?

Humans, after hundreds of years of constant effort, have successfully polluted all bodies of water on Earth. As a result, almost all previously known species of plant, animal, and other life have become extinct. Through natural selection, genetic engineering, and selective breeding programs, a portion of the Earth has successfully repopulated. The following organisms are all that remain: -Photosynthetic sun-basking sharks. Their green fins have chlorophyll to convert sunlight to energy. (autotrophs) -Chemosynthetic goldfish that convert pollution to food. (autotrophs) -Aquatic humanoids whose main diet is aqua-wheat and basking sharks. They have fins instead of legs. (heterotrophs) -Aqua-wheat: one of the few plants that remain, similar to algae. -Terrestrial humanoids with four arms, their diet consists of butter-roaches and fuzzy hamsters. -Tentacled aqua humanoids, they only feed on aqua-wheat and have tentacles for arms and legs. -Cockroaches that feed on humanoid waste. -Giant aqua-spiders that live in water and feed on goldfish and basking sharks. -Green-haired rats that are photosynthetic. -Parasitic mosquitos that feed on any humanoid. -Ten-legged fleas that live on photosynthetic rats and drink blood. -Poison Grass – this plant is a hybrid between grass and poison ivy. The plant is toxic to almost everything (autotroph) -Fuzzy hamsters with green hair that use the sunlight to make their food, thought to be related to rats. -Butter-roaches: genetic engineering created these butterfly-like creatures from cockroaches. Butter-roaches eat poison grass.Question: 1. Identify the defining characteristics for each classification category. Include five distinguishing characteristics for each kingdom, three for each phylum and genus

L.E. is a 16-year-old male, he is seen in the office for a physical exam and second dose of vaccine. L.E. also reported to the student nurse that he will be traveling abroad in 2 months’ time. What is the name of the second dose vaccine that is due for this patient at this age? What information can you provide for this patient, especially since he will be traveling abroad?

how the building blocks from one of the theories could be applied to a health promotion program for your chosen
how the building blocks from one of the theories could be applied to a health promotion program for your chosen audience. When doing this, list each building block of the theory, and define it within the context of the problem you wish to address. Then, brainstorm and develop a number of behavior change techniques that could be used to make changes in the building block. Question:Practice variability affects motor learning. It is the assumption that to perform under variable conditions, such as attempting to make a golf swing, the learner needs to practice under a variety of conditions. In other words, only practicing at the driving range would not transfer well to a real game.Overall, variability of practice seems to be a critical learning and performance issue.1. Provide an example of a specific motor skill that would like to teach.2. After you have selected that motor skill develop a three-week practice schedule, three days per week that shows variability of practice.3. define schema as it relates to motor learning, practice variability, and transfer of motor skills. 4. What is the schema that you are hoping the learner will develop about your skill?Question:Dr. Pearson has recently been hired into the Central City Internal Medicine Group as its fifth physician. He has recently completed his residency and is eager to enter private practice. Dr. Pearson is introduced to Meredith and Dawn, two members of the billing staff for the practice. Unbeknownst to Dr. Pearson, Meredith financially assists the practice in several ways. She bills procedures by using individual codes instead of comprehensive codes, has decided to bill Dr. Pearson’s services under the Medicare number of Dr. Craig (another Central City physician) until Dr. Pearson’s credentialing process has been completed, and habitually submits a claim more than once if she isn’t sure whether it has already been submitted or not. -Describe the compliance / legal issues within this scenario. -Could Meredith be held liable for these activities? -Is Dr. Pearson subject to liability although he doesn’t know Meredith is conducting these activities? -Once Meredith’s activities are discovered, how should her conduct be addressed by her employer, Central City Internal Medicine? – What should Central City do to ensure these types of problems don’t occur in the future?
