<span> Cell Walls – Bacteria (prokaryotes of the domain Eubactera) have cell walls that contain the molecule peptidoglycan. No other type of organism has a cell wall containing this molecule. Prokaryotes in the domain Archea have cell walls, but they are made of materials other than peptidoglycan. Eukaytotic animal cells do not have cell walls. Eukaryotic plants and fungi have cells walls, made of cellulose and chitin, respectively. </span>
There would be no energy.
Mitochondria break down food and convert it to ATP for the body to use.

Answer:
c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.
