Answer:

- Chemical A binds to and blocks Ach receptors of muscle cells

Explanation:

When the Ach receptor in the neuromuscular terminal is blocked by chemical A, the muscles cells will not receive the impulse from the central nervous system. This is the most common type of drug administered to patients during surgery.

In the case of chemical B, flooding the muscle cells' cytoplasm with Ca2+, will cause exactly the opposite, muscle contraction. The reason for this is that high concentration of  Ca2+ in the cytoplasm is an essential part of the mechanism that triggers muscle contraction.

owever, studies are mixed about the usefulness of this practice. One problem in practice is that it is difficult to consume such
damaskus [11]

Answer:

Although the text of your question is incomplete, we can affirm that the reasoning behind the carbohydrate loading is that if an individual increases the amount of carbohydrates that he or she ingests, he or she will have more energy and will be able to perform activities that require a lot of effort physical, with less fatigue.

Explanation:

Carbohydrate is an energetic molecule, as it provides fast energy to our body. Carbohydrate can be acquired through food, mainly in pasta, sweet potatoes, rice, cassava and other foods.

the more carbohydrates a person eats, the more fast energy that person will have and that is the basis of the reasoning behind the carbohydrate loading.

The carbohydrate loading is the term that refers to a type of diet practiced by athletes who participate in exercises that require a lot of resistance, such as marathon runners, for example. This diet consists of greatly increasing the intake of carbohydrates, allowing the athlete to have a lot of body energy and be able to finish his activities with less tiredness. However, this diet is very controversial, first because there is no scientific proof that it works and because the amount of carbohydrate it requires is very difficult to achieve.

What makes viruses different from most other infectious agents?
DanielleElmas [232]

Answer:

All viruses have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. In most cases, they reprogram the cells to make new viruses until the cells burst and die.
