The most important mineralocorticoid regulator of electrolyte concentrations in extracellular fluids is Aldosterone.
Aldosterone hormone is produced by the adrenal gland, it acts in the functional unit of the kidneys to aid in the conservation of sodium, secretion of potassium, water retention and to stabilize blood pressure. The hormone causes water to be absorbed along with sodium ions which increases the blood volume and therefore blood pressure. It indirectly regulates blood levels of electrolytes and helps to maintain the blood pH.
Answer:
Body fat can be divided into two components:
Essential body fat: It is the minimum percentage of fat required by the body in order to function efficiently and to maintain a good health. It is usually stored in small amounts in muscles, internal organs, bone marrow as well as the central nervous system.
Storage body fat: It is also called non-essential body fat as it is not required for the basic functioning of the body. Excess of food or energy is stored in the form of fat around the organs (visceral fat) and beneath the skin (subcutaneous fat) in the body. It serves as the energy reserve and is used when the body's glycogen reserves are depleted.

Answer: A. scalp hairs grow constantly throughout life.
Explanation:
Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells. Hair are made up of protein called "keratin".
The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.
Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).
Scalp hair growth stops because of follicle devitalization when the hair length become two or three feet.
Hence, the correct answer is A. "scalp hairs grow constantly throughout life".
