What is natural selection?
The individuals that are best suited to the environment will survive and reproduce
300
If two organisms belong to the same family, what other taxonomic groups do they have in common?

What two tissues compose the plant vascular system? What is each responsible for transporting?
Xylem - water Phloem - nutrients and water

Distinguish between an adaptation and a variation.
Adaptations improve fitness and increase survival. Variation is differences between members of a species.

What is the purpose of gel electrophoresis?
to sort and separate DNA by size.

Why would lack of variation pose a threat to the survival of a species?
Because without adequate variation, a species is less likely to survive changes to the environment.
