WILL GIVE BRAINLIEST Plants can provide the materials that animals use in cellular respiration, and animals can provide some materials needed by plants for photosynthesis. This image shows the relationship. According to the diagram, which of these materials does cellular respiration provide that plants can use in photosynthesis? a. Chemical Energy b. Carbon Dioxide c. Chloroplasts d. Mitochondria

it is either c or d and i know for sure it is not a or b

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.
