"Anaerobic process that restores NAD+ supply" describes the process of fermentation.
<u>Answer:</u> Option D
<u>Explanation:</u>
"When oxygen is not present or an organism can not undergo aerobic respiration, pyruvate will be subjected to a process" called fermentation. These do not need oxygen, so is anaerobic. Also, will refill NAD+ formed in glycolysis from NADH + H+.
Although in humans, aerobic conditions generate pyruvate while anaerobic conditions go for lactate formation. There are two major kinds of anaerobic respiration involving alcoholic fermentation and fermentation of the lactic acid. These are not the preferred way to release the energy from the glucose molecules but it is the only alternative to survive when energy is needed.
The offspring is most likely all going to be black because if the black is dominant and the speckled is recessive, the black with cover up the speckled! Hope this helped!
Using the given information, the most suitable choice would be the third option. This is because the students are trying to see the effect of temperature on aerobic respiration in earthworms, making this choice the most suitable. Hope this helps!
