Hi there, I'm so sorry no one answer your question here is what I got

The nervous system makes you thirsty. The integumentary system makes you sweat.

The hypothalamus is part of the nervous system and controls vegetative functions, such as hunger, thirst and body temperature. When you run a race, your body starts to lose fluids due to sweat. At that moment the nervous system (through the hypothalamus) trying to maintain homeostasis in your body signals that you are thirsty.

As already mentioned above, when you participate in a race you start to sweat. This is a reaction of the integumentary system, through the skin, releasing fluids to regulate your body temperature.

Explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
