Based on the cell theory, which of the following is true? Large organisms have fewer cells than small organisms. Small organisms have smaller cells than large organisms. All living things are made of more than one cell. Cells vary in size depending on their type.

Large organisms have fewer cells than small organisms

Explanation: Smaller cells have more surface area for oxygen and nutrients

Larger organisms have smaller cells than small organisms. Large organisms are made up of many small cells such that there is an increase in the amount of surface area in comparison to volume. This gives the large organism a better chance at survival.

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.
