The carbon dioxide breathed out is a by-product of the process of cell respiration, as is water. In this process, energy is produced in the mitochondria of cells. This energy is our physical "life force". Both oxygen and glucose are required for this.
The correct answer is: Differentiate
Every cell in a multicellular organism has an identical genome, and yet, there are various cell types. These varieties are the result of highly controlled modifications in gene expression (different sets of genes must be turned on and off).
Cellular differentiation almost never involves a change in the DNA sequence itself. Therefore, different cells can have very different physical characteristics regardless of having the same genome.
I'd mark answer B :) technically it means that you must eat enough food rich in those aminoacids because they can't be synthesized by the organism.
