The process of changing a higher form to a lower form is called a. claudication. b. contracture. c. crepitation. d. degeneration.

D. degeneration.

Explanation:

The term degeneration refers to the notion that species can return to a primitive state over time - a process that would be opposed to biological evolution. That is, according to degeneration a species may move out of its higher form and back into a lower, less evolved form.

In short, degeneration occurs when through the loss of characteristics that allow an organism to evolve evolutionarily, it loses beneficial qualities, such as strength and intelligence, and returns to a primitive state.

"do a testcross with a homozygous recessive plant."

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
