Answer:
A.when it reaches the top of its flight
Explanation:
This theory is base on gravitational potential energy which state that potential energy in an object increases as weight and height increases.
the amount of potential energy stored by an object depend s on the mass and height.

Different peacemakers are stimulated in different areas of the heart. This peacemaker impulse is implanted next to the collarbone, the surgery is done under local anesthesia.</span>
answer; Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. ... Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Updated January 06, 2020. A gene is a portion of DNA that determines a trait. A trait is a characteristic, or a feature, passed from one generation to another, like height or eye color. Genes come in multiple forms or versions. Each of these forms is called an allele

I like to think of the DNA molecule strand as a ladder, rather than a spiral staircase. The siderail of the DNA ladder (The DNA "Backbone") consists of the Sugar and Phosphate molecules. The rungs of the ladder (the inner bases) consist of the pairs of Nitrogen Bases - Adenine, Guanine, Cytosine and Thymine.
hope this helped :)
