Marisol has been chewing and swallowing her food, but her digestive system is not doing what it usually does. why is this a problem for her ability to exercise?

Digestion is the process of breakdown of the large food particles into the small substances and absorbed by the body. The digestive enzymes and digestive juices are required for the digestion.

The Marisol digestive system is not working although she swallow her food. This may affect her exercise as the cells are not able to get work. The food particles are not broken down and absorbed by the cells, This causes the energy deficiency in her cells and she is not able to do normal physical work properly.

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.
