Answer:
The answer is D.
Explanation:
According to the information given in the example, Zack is most likely to have suffered damage to his brain's frontal lobe becasue of the symptoms that he show such as a change of personality. Frontal lobe is located at the front of the brain and it is responsible for controlling functions such as judgements, decision making, personality traits, emotions and memory which are all among the most important things for someone to function properly. So the correct answer is D.

Answer:
Group 4
Explanation:
The control group in this case would be those students in group 4.
<u>The control group during an experiment is a group that does not receive the treatment administered to other groups and as such used as a standard for measuring the effects of the treatment on other groups. </u>Whatever differences that exist between the control group and the various treatment groups is attributed to be as a result of the treatment administered to the groups.
In this case, group 4 only used warm water for washing their hands instead of the hand sanitizer/soap used by the other groups. Whatever differences found out in the bacterial count in their respective culture swabs can be attributed to the effects of the hand sanitizer/soap.
By injecting Mesenchymal Stem Cells with ability to express high amount of Akt or protein kinase B in myocardium, researchers witnessed restored cardiac function and inhibition of ventricular remodeling. The effect was seen after two weeks of administration of cells. The culture containing hypoxic Akt-MSCs (conditioned medium) inhibits apoptosis or cell death induced due to hypoxia. Also, it triggers in vitro contraction of cardiomyocytes, the cardiac cells specifically responsible for contraction function.
The desired functional improvement can occur in short time which is less than 72 hours, the reason for which was hypothesized as paracrine action of cells. Hypothesis was proved by upregulation of genes that code for factors responsible for above mentioned effects (apoptosis and contraction). The factors are FGF-2, VEGF, HGF etc.
