1 A cell gains energy by combining glucose with oxygen in a series of chemical reactions. The products are carbon dioxide and water. What is the source of this energy?

A. the forces that attract protons and neutrons within carbon nuclei

B. the breaking of chemical bonds within the molecules of the reactants

C. the breaking of chemical bonds within the molecules of the products

D. the kinetic energy of oxygen molecules

E. strong forces within the atomic nuclei of the reactants

The answer my teacher gave me was: Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.

Explanation:

Good luck with the rest of your questions! :)

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
