Answer:
muscle cells will become paralyzed when there is a lack of acetylcholine
Explanation:
Based on the information provided within the question it can be said that in this scenario the muscle cells will become paralyzed when there is a lack of acetylcholine. That is because the Acetylcholine (ACh) is an organic chemical within the brain and body that acts as a neurotransmitter to send signals from the brain to the muscle cells. Without those signals the muscle cells cannot respond and are therefore paralyzed.
Going upward from the surface, it is the point where air ceases to cool with height, and becomes almost completely dry. More formally, the tropopause is the region of the atmosphere where the environmental lapse rate changes from positive, as it behaves in the troposphere, to the stratospheric negative one. Following is the exact definition used by the World Meteorological Organization:
The boundary between the troposphere and the stratosphere, where an abrupt change in lapse rate usually occurs. It is defined as the lowest level at which the lapse rate decreases to 2 °C/km or less, provided that the average lapse rate between this level and all higher levels within 2 km does not exceed 2 °C/km.<span>[1] for example</span>
Answer:
D
Explanation:
The neuroendocrine system is made up of the cell in the body that ‘sit’ between the nervous system and the endocrine system. These cells are like the pituitary gland, islets cells of the pancreas, thyroids, and etcetera. They receive nerve impulses from nerves connected to them. The impulse then triggers them to release respective hormones into the blood.
