Answer:

Ions are some atoms with charges.

Explanation:

This ions could be positive or negative, they are formed because the atom gained or lost some electrons in their internal structure.

In the human body, they are very common because they are constantly formed, for example in our cells membranes, we need some potassium and calcium ion to transport water inside the cells.

Also this ions are formed when we eat food during digestion process, some of this ions are the responsible for aging.

Hope this info is useful.

Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.

olga2289 [7]

Answer:

A) ADH secretion decreases. B) Urine osmolarity decreases.

Explanation:

Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.

A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.

B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.

I hope this answer helps.

Bad White [126]

Answer:

B) Telomerase is a ribonuclear protein containing a section of RNA complementary to the telomeres

C. telomerase is reactivated in cancer cells, contributing to their immortality

Explanation:

Telomerase elongates telomere ends
Telomerase binds to a RNA molecule containing a sequence complementary to the telomeric repeat.

Telomerase is usually not active in somatic cells but is active in cancer cells- the protein acts to extend the shortened telomeres in these cells preventing them from dying
