In humans, the medulla region of the brain is mainly responsible for the regulation process of respiration. It is also called the respiratory rhythm centre. The chemosensitive area located near the respiratory centre sends signals across nerve impulses to alter the rate of expiration to eliminate compounds.
<span>in an environment where there is little or no oxygen. aerobic respiration requires oxygen ad when it is not present fermentaion (anaerobic respiration) occurs because it works when oxygen isn't there</span>
B - The environment within the cell is stable.
Homeostasis is when your body works to maintain equilibrium (balance) so within a cell, the cell would be stable
Protein
synthesis<span> is the process that provides the instructions to build
proteins. Enzymes in the cells nucleus
begin the process, or synthesizing the protein and unwinding the needed section
of DNA. <span>RNA is formed and copies one
side of the DNA,, it is then sent to other areas of the cell to bring different
amino acids to form proteins. </span></span>
