Bradley is standing on the top of a mountain holding a soccer ball. which of these best describes what happens when he throws the ball over the edge?
a)
the kinetic energy increases and so does the total amount of energy.
b)
the kinetic energy decreases and the total amount of energy increases.
c)
the potential energy decreases and the total amount of energy also decreases.
d)
both the kinetic and potential energy change, but the total energy remains constant.

A)The kinetic energy increases and so does the total amount of energy.  

B)The kinetic energy decreases and the total amount of energy increases.  

C)The potential energy decreases and the total amount of energy also decreases.  

D)Both the kinetic and potential energy change, but the total energy remains constant.

The answer to this question is D) Both the kinetic and potential  energy change, but the total energy remains constant.

c. movement because i took the test and it lets me review my answers

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
