The body loses water in a variety of ways. Put the water output mechanisms in order from greatest contribution to fluid loss (1)
kirza4 [7]

The maximum to minimum body water loss occurs by: Urine production, Skin losses, Lung respiration and minimum by Feces

<h3>What are the ways in which body loses water ?</h3>

Through breathing, sweating, and peeing, the body continuously loses water. You become dehydrated if you don't drink enough water or other liquids.

The majority of fluid loss happens through the stools, sweat, and urine, but it's not only those things. The quantity of body fluid lost daily through the skin, respiratory system, and water in the feces that cannot be readily measured is known as insensible fluid loss.

Physical exercise also influences increased respiratory water loss due to the increased expiratory volume and frequency of breathing. Various environmental elements like temperature, humidity, radiation, and atmospheric pressure mostly affect sweating and urine water loss.

Feed-back inhibition is said to occur when the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway.

How is the mass number calculated for an element? A. The difference between the mass and the protons B. There is no calculation.
Nana76 [90]

The best answer is D.

The mass number of an element is the sum of the number of protons and the number of neutrons. Protons and neutrons both weigh about one atomic mass unit or amu.

The nucleus of an atom is made up of protons and neutrons. Both these two types of particles are almost the same size.  Almost all the mass of an atom (99%) is in the nucleus. Atomic mass therefore is really a measure of the size of the nucleus.
