The answer is; graph A
Breathing increases during exercise because the body is demanding more oxygen for the muscles. The hypothalamus detects the increased carbon dioxide in the blood dur9ng exercise and its commands the lungs to breath faster and deeper. When exercise stops, the body is restored to resting through homeostasis.
Answer:
The term describes cellular respiration
Explanation:
Cellular respiration, also known as internal or tissue respiration can be represented by the equation:
C6H12O6 + 6H2O ---> 6H2O + 6CO2 + Energy (in form of ATP)
From the equation, glucose from the blood is oxidized by oxygen trapped from the air by the nostrils. The main purpose of cellular respiration is to generate energy required by the body for various life activities
Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.
- Telomeres are repetitive sections at the very ends of chromosomes that are present in a variety of eukaryotic species, including humans and unicellular protists.
- Each round of DNA replication wears down a little portion of the telomeres, which serve as caps to safeguard the interior chromosomal regions.
- Most somatic (body) cells do not typically have telomerase activity, but certain adult stem cells and germ cells—the cells that produce sperm and eggs—have.
- Adult germ cells, tumor cells, and fetal tissues all contain telomerase. Telomerase activity is controlled during development and is extremely low in somatic (body) cells, virtually undetectable. These somatic cells age because they do not frequently use telomerase.

Answer:
C, D
Explanation:
The common property of all proteins is that they consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon atom also carries a carboxyl group (―COOH).
Answer:
It will not be significantly altered.
Explanation:
During an eight-hour fast glycolisis and cellular respiration will continue to function normally and the production of ATP would not be altered significantly, because there is a source of energy-rich molecules used in catabolism from glycogen stored in muscles and the liver, or fats stored in the fatty tissue or the muscle's protein themselves that can be used as a source of energy.
