Evolution Answers

Use the theory of natural selection to explain the changes seen in the mating calls of the new isolated southern male frogs

Dolphins and fish have similar body shapes. Is this feature more likely a homologous or analogous trait?

Explain your answer.

a. Analogous-Dolphins are mammals and fish are not, thus their evolutionary paths are quite separate. They have similar body shapes because of their similar environment.

b. Analogous-Dolphins and fish are both vertebrates, thus they share an evolutionary history, causing them to have similar body shapes.

c. Homologous-Dolphins and fish are both vertebrates, thus they have a similar recent evolutionary history, causing them to have similar body shapes.

d. Homologous-Dolphins are mammals and fish are not, thus their evolutionary paths are quite separate. They have similar body shapes because of their similar environment.

In the 100 photos that you examine, 41 cats have white hair on more than 50% of their bodies, 24 cats have white hair on less than 50% of their bodies, and 35 have no white hair at all. Add this information to the appropriate cells in the ‘Observed #’ column in Table 5.

5. Use the data to determine the S and sallele frequencies at the spotting locus. Show your work and/or reasoning.

4.1Discuss the dynamics of drug dependence and provide examples to substantiate your answer

Describe enteral and parenteral administration of drugs and explain how oral, intravenous, intramuscular or subcutaneous administration of a drug impacts on the pharmacokinetic parameters of the drug.

Using examples, briefly discuss how evidence is used to support evolution. Do you agree with the use of this data/evidence? Explain your position.

In your assigned readings, you learned about different theories for the evolution of eukaryotic cells from prokaryotic organisms. Describe the hypothesized steps for the evolution of eukaryotic cells via endosymbiosis. How is evidence used to support this theory? Explain your position.
