Question

There are 5 related organisms: A, B, C, D, and E, If A and B are the most closely related, what is true those two organisms? Organisms D is their closest common ancestor. They have more traits in common with each other than the other organisms. A and B are not similar at all. Which of the following would be environmental influences on a population of pine trees? Birds that eat/disperse the seeds are migrating south sooner. Moss grows on the north side of many oak trees. The trees are getting taller over time.

Answer 1

Question 5

As given in the data, A, B, C, D, and E are related organisms. Also, A and B are the most closely related. This means that A and B have a common ancestor. However, there isn't enough data to specify as to which one of the others (from C, D, and E) is the common ancestor. Thus, the answer is that they have more traits in common with each other than with the other organisms.

Question 6

The growth of moss on the north side of Oak trees is not relevant. Also, the increase or decrease in height of the pine trees over time does not affect the population of the trees. However, early migration of birds involved in the dispersal of seeds can be called an environmental influence. A mismatch in the timing of fruit and seed production and the migration of birds involved in the dispersal of seeds can adversely affect the population of pine trees. Early southward migration of birds is the answer.
