Answer:
C
Explanation:
This is placing a cell in hyper tonic solution.Therefore, the water potential of the cells is higher than the environment. Hence it lose water to the environment which has a lower water potential, but higher solute potential.
Therefore the loss of fluid by the cell leads to shrinking of the cytosol and it containing organelles. Later the cells collapse.

Esto es colocar las células en una solución hipertónica. Por lo tanto, el potencial hídrico de las células es mayor que el del medio ambiente. Por lo tanto, perder agua al medio ambiente reducirá el potencial hídrico, pero aumentará el potencial de soluto.
Por lo tanto, la pérdida de líquido por parte de la célula conduce a la contracción del citosol y que contiene orgánulos.
An <u><em>antidepressant</em></u> such as Prozac mimics the effects of the nurotransmitter serotonin, whereas a <em><u>dopamine antagonist</u></em> include antipsychotic drugs that block the action of theneurotransmitter dopamine.
Answer:
Glycogen synthase is phosphorylated at only one site.
Explanation:
Glycogen synthase has multiple sites where phosphorylation can occur. Glycogen synthase may have 9 or more sites where it can be phosphorylated as a result of which it's activity is down regulated. It simply means that the regulation of this enzyme does not occur through binary on/off switching, in fact it's activity is modulated over a wide range in response to various signals.
In contrast to glycogen phosphorylase which gets activated when it is phosphorylated at it's serine residues, glycogen synthase gets inactivated by phosphorylation.
As soon as another enzyme GSK3β phosphorylates glycogen synthase, it gets inactivated as a result of which glycogen synthesis halts in the liver.

While it may seem daunting, a basic meringue is nothing more than a mixture of beaten egg whites and sugar.
Answer:
zero
Explanation:
Displacement is a vector, meaning that the direction is very important. Displacement is the distance from the starting point to wherever the object is. So a car that does a 500 m lap will have covered 500 m in distance but displacement is zero because, having come back to the starting point, the distance between the starting point and where the object is, is zero.
