FinnZ [79.3K]
Pyridoxine contains 11 hydrogen atoms, 8 carbon atoms, 3 oxygen atoms, and 1 nitrogen atom. The chemical formula would be C8H11NO3. A chemical formula of a substance tells the number of atoms of the elements that is involved in the compound. Pyrodoxine is commonly known as vitamin B6. It is mostly found in food like meat, whole grains, nuts and avocados. Also, it is can be present in dietary supplements. It has a number of important functions in the body. Dietary supplements are manufactured to prevent vitamin B6 deficiency. Also, it is used in treating a specific type of anemia or the lack of red blood cells.

Answer:

It helps the body remove heat through sweating.

Explanation:

When the weather is hot, the body tries to keep cool by sweating. The high specific heat capacity means that the body doesn't have to lose much water to stay cool.

The high specific heat capacity of water doesn’t heat the body, but it slows down the rate of heat loss when the weather is cool.

B is wrong. The body uses glucose, not water, as an energy source.

C is wrong. The high specific heat capacity of water is not connected with the body's ability to store it.

D is wrong. The high specific heat capacity of water doesn't heat the body, but it slows the rate at which it cools.
