<span>Stretching that uses neuromuscular reflexes to gain further stretching of the muscle is called "PNF stretching".

PNF stands for Proprioceptive Neuromuscular Facilitation and it refers to a further developed type of flexibility training that includes both the extending and contraction of the muscle assemble being focused on. Proprioceptive Neuromuscular Facilitation extending was initially created as a type of recovery, and to that impact it is exceptionally viable. Proprioceptive neuromuscular Facilitation (PNF) is a powerful method for utilizing reflexes to help muscular relaxation.
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).
1. A gamete is a haploid cell that fuses with another haploid cell during fertilization in organisms that sexually reproduce
2. Spores participate in both sexual and asexual reproduction unlike eggs and sperm
3. Sperm are continuously produced by males, while a female is born with a full supply of eggs.
4. A sperm cell fertilizes an egg cell. In sexually reproducing organisms including plants, life starts as a single-celled zygote which is formed by the fertilization of sperm and egg.
5. I would think it's C as all plants have spores.
Proprioception controls the position of muscles.
