When gene frequencies stay relatively constant, Hardy-Weinberg equilibrium occurs. HW equilibrium occurs in large populations with random mating, with no migration, mutation, or natural selection. In this case, the proportion of dominant homozygous equals the square of the frequency of the dominant allele (p2), the proportion of recessive homozygous equals the square of the frequency of the recessive allele (q2<span>) and the proportion of heterozygotes equals 2pq.</span>

Answer:
The Pepsi he drinks at 10 pm
Explanation:
Pepsi is a caffeinated drink that has caffeine in it. Caffeine is a stimulant which means it keeps the body awake and alert. Caffeine works by mimicking adenosine. Adenosine is produced by neuron cells and when it binds to its own receptors (autocrine signaling) it triggers the neurons cells to continue firing. As the adenosine levels fall as the day progresses, the brain is signaled that it is time rest. Adenosine levels are at the lowest when its almost bedtime. However, when Jon takes Pepsi, the caffeine in it bind to the adenosine receptors and make the brain neurons to keep ‘firing’.
