I do not know the options, but, follow this criteria and you should be able to finish the exercise:
Usually, animals that are in captivity are endangered animals, with few individuals left. When we captivate them, the risks of them dying (either naturally or by poaching, hunting, contamination, etc) is lower, since we are taking direct care of them.
Hope it helped,

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

Answer:
Blood leaves the heart through the pulmonic valve, into the pulmonary artery, and to the lungs. Blood leaves the heart through the aortic valve, into the aorta, and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs, and body.
