Explanation:
Peripheral nervous system consists of 3 major neuronal levels: vegetative (reticular formation and brain stem), limbic system and neocortical level. The RAS is the link between the brain and the spinal cord.
Brain stem consists of pons, medulla oblongata and mesencephalon. Brain stem is responsible for involuntary functions such as heart beat, respiration and vasomotor activity. Limbic system represents the emotional control center. It consists of thalamus, hypothalamus and pituitary gland and maintains homeostasis. Neocortical part processes sensory information and regulates emotional responses.
Autonomic nervous system (ANS) regulates visceral activities and organs (circulation, digestion, respiration and temperature). ANS has two divisions: sympathetic and parasympathetic nervous system.Parasympathetic nervous system regulates homeostasis via the release of acetylcholine (Ach). Parasympathetic nervous system is responsible for energy conservation and relaxation.
There are three stages in the stress response: immediate effects of stress, intermediate effects of stress and prolonged effects of stress.
Answer:
When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.

Bodybuilders in particular need the lower body fat percentage possible in order to succeed in their career, since most of their bodies must be muscle. Professional ballet dancers need to be light and skinny to be able to perform their dance moves and to be lifted by their partners; a basketball player also needs a lower fat percentage and a higher muscle mass percentage to be able to play at his best; and a ranch hand as well needs to not be packing that much fat in order to make his job easier.
Pregnant women, however, need body fat to have healthy pregnancies. This doesn't mean that they do not need to take care of themselves, because a higher body fat than what it's needed can lead to diabetes, high blood pressure and can difficult the pregnancy.
