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’.

Hoochie [10]

7/16

Explanation:

<em>The proportion of the offspring from the cross that will have white flowers is 7/16.</em>

The presence of anthocyanin which determines purple coloration is conditioned by the C_ and P_ alleles. It means that the absence of one or both of C and P will result in white flowers.

Two plants, each with CcPp are crossed:

CcPp x CcPp

Offpring

1 CCPP - purple

2 CCPp - purple

2 CcPP - purple

4 CcPp - purple

2 Ccpp - white

1 CCpp - white

1 ccPP - white

2 ccPp - white

1 ccpp - white

Proportion of offspring with white flowers = 7/16

Proportion of offspring with purple flower = 9/16

<em>See the attached image for the Punnet's square analysis of the cross.</em>
