Answer:
C
Explanation:
Prokaryotic cells doesn't have any nucleus, so the first one is incorrect. No cell can function without genetic information, so the last one is incorrect. Plasmids are present only in Eukaryotic cells, so the second one is incorrect. Which leaves the third one as correct.

Answer:
B. At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell?
Explanation:
Organelles are specific in their functioning and hence, each organelle contributes its own quota to the cell's proper functioning. According to the question, a muscle tissue is being worked on to determine the effect of a missing or damaged organelle on its cell.
Mitochondria are organelles found in all eukaryotic living cells. They are the organelles responsible for the synthesis of ATP (energy) used by the cell as a result of the glucose that gets converted in them during cellular respiration.
Therefore, to determine if the muscle cells are functioning properly, the question that: At what rate do the mitochondria of the cell need to convert glucose to usable energy molecules to meet the high energy needs of the cell? should be asked.
Note that, Chloroplast and cell wall are not found in muscle cells, which is an animal cell. Likewise, ribosomes are not organelles for synthesis of glucose.
<u>Answer:</u>
<em>A plasma membrane is the cellular structure that makes it possible for a cell to differ structurally and biochemically from its surroundings. </em>
<u>Explanation:</u>
<em>Plasma membrane</em> is the surrounding of all the cells. The function of plasma membrane in a cell is to regulate the incoming and outgoing elements from the cell.
<em>Phospholipid bilayer</em> is the main composition of plasma membrane. It makes the cell different from each other structurally as well as makes the cell different in <em>chemical composition </em>too.
Answer:
b. Aldosterone promotes sodium reabsorption in the kidneys.
Explanation:
Once it is produced by the adrenal gland it stimulates the mineralocorticoid receptors on the distal tubule and collecting duct of the kidney's nephrons. This causes sodium reabsorption in the kidneys indirectly affecting water retention.
