A long reflexive pathway has an advantage over a short reflexive pathway in the fact that they can be also be stimulated by the central nervous system, whereas the short reflexive pathway is only stimulated by the enteric nervous system.
Answer:
used in an experiment as a way to ensure that your experiment actually work
Explanation:
Plants may wilt because the soil is dry and the plants don't have enough to water to survive. If you add shade, this means that the sun no longer shines down directly on the soil, helping the soil stay damp. Less water evaporates from the soil, and the plants don't wilt as much.
Answer: Lack of energy
Explanation:
Oxygen is needed in a process known as Respiration where it is used to produce energy from glucose. This energy is what the cell uses to continue whatever functions that it carries out which are needed for the body to survive. If the cells don't get oxygen, they can't make energy and if they can't make energy, they die.
Some cells are more important than others and so will need a constant supply of oxygen. The brain for instance requires 20% of the oxygen used in the body. If the body suffers from a lack of oxygen for whatever reason, brain cells begin to die within about 4 minutes.
The brain is extremely important as it directs the body. If the cells there begin to die, the body deteriorates and the body stops engaging in certain processes due to a lack of direction from the brain. This coupled with the other cells dying around the body will lead to even more deterioration till the body dies.
