adaptor proteins are responsible for the recruitment of cargo molecules into a growing clathrin-coated pits
The muscles that contract (during cold or fright), the slanted hair follicle is pulled upright, dimpling the skin surface with goosebumps are called arrector pili muscle.
The arrector pili muscle are tiny muscle that attaches to the base of the hair follicle at one end and to the dermal tissue on the other end. When the body feels cold or fright the body generate heat and the arrector pili muscle contract all at once, that causes goosebumps on the skin.
The arrector pili muscle acts as the thermoregulator. Straight stand hair increases air trapping, so that the heat loss from the body decreases. The arrector pili muscle are mediated by the sympathetic nervous system.

Answer:
Because sickled cells restrict blood flow, individuals can periodically experience swelling and extreme pain in any body organ or joint. This can last for hours or weeks. Sometimes permanent damage can occur to organs deprived of oxygen and nutrients
Explanation:
Red blood cells are designed to pick up oxygen in the lungs and transport it throughout the body via the circulatory system. Their donut-like shape and water-balloon-like flexibility allows them to pass through even the tiniest blood vessels.
Sickle cell anemia is a hereditary condition that causes some red blood cells to distort into rigid crescent moon shapes.
Normal red blood cells can flow freely through blood vessels. Sickled cells get stuck in the blood vessels and cause blockages.
Positive - Due to urbanization, the people of rural areas settle in urban cites. These reduces the labour work which was done in rural areas and as they get water and electricity. The reduced labour work help them in maintaining their physical health
Negative - If people continues to enjoy the facilities and sit ideally doing nothing is much more worse than the above one. It causes obesity and can ultimately lead to heart attack
