Answer:
You should come back immediately, but not fast, to the surface and get fresh air.
Explanation:
Scuba diving is the practice of diving that consists of partial or total submersion in the water, using for this purpose, a self-contained breathing apparatus, also known as diving equipment.
During scuba dive, a lot of problems can happen because of the depth and compression of the air, so in any case of feeling ill, you need to come back to surface.
In scuba diving, the diver is assisted by equipment that he carries with him and allows him to breathe underwater. Although physical activity is healthy even for those with a basic respiratory disease, diving is a sport that requires redoubled care. When the individual dives, the gases in the diving cylinder dissolve in the blood because of pressure greater than atmospheric pressure. The phenomenon becomes more intense depending on the depth and gases used. Compressed air gas is the most common used in recreational diving. At greater depths, gas mixtures such as helium and oxygen or helium, oxygen and nitrogen are used.
The main problem is not the dive itself, but the risk of decompression when the individual rises too quickly to the surface. Residual nitrogen is the nitrogen remaining in the body after a dive, whose delay time to be eliminated depends on the dive time and depth reached. If the elimination of residual nitrogen is deficient (due to health or external factors such as a very rapid climb), nitrogen bubbles that cannot be eliminated from the human body can become trapped in tissues or in the bloodstream. This occurrence is called decompression sickness. When this occurs, gas bubbles form in the circulation that can cause myocardial infarction (heart attack) or stroke (stroke).

There are numerous circumstances that give pathogens the chance to harm people.
The first occurs when an infection has already weakened the immune system. In situations like this, other pathogens may infect the host opportunistically and cause an infection. If the human host does not maintain proper personal and environmental hygiene, that is another condition. Many pathogens thrive in unclean environments, so by failing to maintain proper environmental hygiene, a person increases his risk of contracting a pathogen.
Finally, since so many pathogens are transferred by vectors, humans are more likely to contract the diseases that these vectors aid in spreading if they do not take the necessary precautions to stop their activity.

Answer:
The correct answer is - option A.
Explanation:
response to the hormones leads to different kind of the changes in the cellular level and body level. Hormonal response is amplified as the signalling pathway progress.
Hormone stimulus produces various proteins and enzymes that changes the cellular membrane permeability, induces secretory activity, and activates and deactivation of the enzymes. It does not produce an action potential.
Thus, the correct answer is option a.
