Answer 1

11B (reproduce). 12C (be eaten). 13A (variation). 14C (better adapted). 15C (Darwin). 16A (evolved). 17C (competition).

Step-by-step explanation:

11 - The key principle underlying evolution by natural selection is that traits are only passed on if the organism survives long enough to reporduce. An adaptation that increases its likelihood of survival will therefore increase the chance it will reproduce.

12 - Deer rely on their brown fur to remain camouflaged in the forest so that predators can't see them. A white deer will stand out and will be seen by predators and eaten.

13 - This is the definition of variation. The variation becomes an adaptation if it actually benefits the organism in some way in its environment. A variation could also be neutral (doesn't affect the organism) or deleterious (bad).

14 - See previous question.

15 - Darwin developed the theory.

16 - This is describing the process of evolution.

17 - This is an example of competition.
