Answer:
· Fermentation does not generate any additional energy, however, NAD+ is regenerated. In the presence of oxygen, pyruvate is oxidized and acetyl CoA is formed, which feeds into the citrate acid cycle and the complete oxidation of glucose.

the answer is true, hope this helps :)
The controlled experiments are performed by the scientists, when they want to study the changes in the sample on changing a single variable. So, the correct answer is option (b).
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living thing as well as non living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect.
The nervous system conserves energy, while the sympathetic nervous system consumes energy.
<h3>What is the nervous system?</h3>
The nervous system is an organ system that coordinates the activities of muscles, monitors organs, constructs and processes data received from the senses and initiates actions.
The nervous system can either be the following;
- Sympathetic
- Parasympathetic
The sympathetic nervous system is a part of the autonomic nervous system that raises blood pressure and heart rate, constricts blood vessels, and dilates the pupils when under stress.
On the other hand, the parasympathetic nervous system is one of the divisions of the autonomic nervous system, based between the brain and the spinal cord, that slows the heart and relaxes muscles.
This suggests that the parasympathetic nervous system conserves energy because it slows the heart while the sympathetic nervous system consumes energy.
