1) The two largest marine predators are killer whales (orcas) and big sharks such as great whites. Assume that a killer whale and a great white shark of the same size and weight are capable of swimming at the SAME maximum velocity and that one is chasing the other. Assume that both animals swim at or very near the surface of the ocean. Which one would be able to escape from the other? Carefully explain why after you write an hypothesis.
2) There are two different species of single-cell animals (ie, each animal consists of only one cell) living in the same environment. They are identical except that the animals of one species are three times as big as the other. Suddenly their environment becomes dramatically worse: the nutrients that each species requires become far less abundant than before. Under this set of now-unfavorable conditions the number of animals in the smaller single-cell species remained constant for quite a while before the population began to decrease as the small-cell animals died from starvation. The larger single-cell animal species, however, started to disappear very soon after the change of environment and completely disappeared long before the smaller ones did. Why did the species of smaller cells survive longer than did the larger-cell species?
