Part 1: Evolutionary Forces - Mechanisms of Change within Populations

1 Which of the following statements is FALSE about mutations?

A Mutations are changes in DNA.

B Mutations can be good.

C Mutations are caused when populations need to change.

D Mutations happen randomly.

E Mutations lead to variation in populations.

2 Pandas only eat bamboo. The only bamboo forest in the world is currently being cut down. What is likely to happen to the panda population over time?

A Since pandas need to change, they will adapt and eat something new

B The changing environment will cause some of the pandas to mutate their DNA and develop new eating habits.

C The pandas will have to move to a new place and eat something new.

D The panda population might change if there is a mutation that allows some of them to eat something else, but this is unlikely and would be random.
