Answer:
Cells that respond to peptide hormones usually do so through a sequence of biochemical reactions involving receptor and kinase activation. In order for cells to respond, it is necessary for first and second messengers to communicate. This is possible because <u>C) G protein acts as the link between first and second messengers </u>.
Explanation:
When the first messengers join the receptor, in the external membrane of the cell, it produces a change in the shape of the receptor that causes the join of the G protein to this structure. The G protein joined to the receptor and the first messenger modulates the activity of the second messengers inside the cell.

Answer:
<h2>
False</h2>
Explanation:
The human body mechanisms try to excrete out the ethanol from the body before it gets circulated in the body through blood. The body does so by converting the ethanol to certain metabolic products which get filtered and excreted out through urine.
The metabolism of alcohol takes place in the liver in two steps- Ethanol is converted to acetaldehyde by the alcohol dehydrogenase enzyme. The acetaldehyde is toxic to cells and is the compound responsible for the hangover after drinking.
The acetaldehyde is then converted to acetic acid by an enzyme called acetaldehyde dehydrogenase. The acetic acid through respiration gets converted to water and carbon dioxide and rest is excreted out through urine.
Thus, the liver is the organ responsible for the metabolism of ethanol and not pancreas.
Answer:
Hypotonic solution
Explanation:
The solution with lower solute concentration is referred to as hypotonic solution while the other with higher solute concentration is called as hypertonic solution.
Since the solution concentration on inside of the cell is lower than that of solution present on the outside the cell; the solution inside the cell is hypotonic.
Interphase! Most cells are in this phase and in it they copy DNA and prepare for mitosis, hope I helped
