Answer:
highly active individuals who sweat heavily
Explanation:
Dietary Reference Intake (DRI) for sodium is stated at 1,500 mg daily for sedentary individuals, men and women under the age of 50, and is adequate for normal functioning of the body, as too much intake for these categories of people might be unhealthy.
However, highly active individuals who sweat heavily, such as athletes, would need to consume a higher amount above the recommended 1,500 mg for others.Sodium is required for maintaining fluid balance as muscles and neurons need to be activated by Sodium, which is an electrolyte. Highly active people tend to lose more sodium as they sweat profusely, hence the need for a higher intake of sodium to avoid weakening of the muscles and cramps.

Thus, the correct answer is option (A).
Answer:
The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship. Mitochondria formed when bacteria capable of aerobic respiration were ingested; chloroplasts formed when photosynthetic bacteria were ingested. They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.
