What would happen if a freshwater fish did not produce lots of watery urine

     The right answer to this question is: Water would come out of the fish by a process called osmosis.

Explanation:

     This could happen for a series of reasons, but the main one is that, fish produce a watery urine because, if they had the same urine as we, humans, have, their body wouldn't be adapted to it inside the water. A watery urine is highly soluble in water , and this helps the fish not to contaminate the water he lives in.

        Osmosis works in a way that will always balance both sides of the equation, and this would happen with water, their body would balance the quantity of water in and out of the body.

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.

the answer would be d : p
