A. Organisms with less desirable traits do not reproduce
is the answer
Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
Answer: 3d illustration depicting cell division, a process whereby a cell divides into two new daughter cells with the same genetic material.
Explanation:
The answer is the hypothalamus. It is a portion
of the brain that comprises a quantity of small nuclei with an assortment of
functions. One of the most significant purpose of the hypothalamus is
to connect the nervous system to the endocrine system through the pituitary
gland.
