The digestive system and the excretory system both excrete waste. which best describes how waste is secreted in each system? the digestive system excretes a liquid waste and the excretory system excretes a solid waste. both systems excrete waste as a liquid. both systems excrete waste as a solid. the digestive system excretes a solid waste and the excretory system excretes a liquid waste.

The best description would be - the digestive system excretes a solid waste and the excretory system excretes a liquid waste.

Explanation:

The digestive system and the excretory system both secrete or eliminate waste from the body. The digestive system secretes waste through the rectum and the excretory system secrets waste with the help of kidneys through urinary bladder.

The digestive system removes the indigestible food in the form of solid waste or feces from the body, this process is called defecation or elimination.

The excretory system secrets metabolic wastes, such as ammonia, in the liquid form from the body through urinary organs.

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.
