Answer:
Charles Darwin
Explanation:
Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.
In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.

In animals, vacuole is small and responsible for the storing of waste products that are produced in the cell.
10 pounds
10% of energy moves on through each trophic level so if a chicken ate 10 pounds of a producer that would be equivalent to the fox eating 1 pound of chicken. (10 times .1 = 1)

mitosis is needed for growth, repair, replacement, asexual reproduction.
it maintains same chromosome number
