The movement of particles in diffusion are determined when particles from one area go to another with little or no particles.
Answer:
The size is reduced as 80-95% of the available energy at one trophic level is not transferred to the next
Explanation:
There is loss of energy as it is transferred between trophic levels. The decrease in energy as it moves up the pyramid is due to energy loss as metabolic heat when one organism is consumed by another from the next level as it moves up the trophic levels.
Answer:
The correct answer will be-ventral ramus
Explanation:
Rectus abdominis is a skeletal muscle found in the front part of the body which begins from the sternum and ends at the pubic zone.
Rectus abdominis is also known as "Abs" which viewed externally appears to be six, eight or ten in number.
These muscles are innervated by the thoracoabdominal nerves which carry and transmit signals to CNS and to the muscles back. The main spinal nerve which controls the movement of Abs is known as the "ventral ramus".
Thus, ventral ramus is the correct answer.
Answer:d) contracting her pupils and increasing secretion of stress hormones.
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.
