Fermentation is the process by which a carbohydrate molecule is broken down into alcohol and carbon dioxide in the absence of oxygen. During this process, two molecules of ATP is produced. In the absence of oxygen, pyruvate formed from glycolysis will undergo fermentation process. During the process of fermentation, NADH from glycolysis will be converted back to NAD+. This is necessary in order for glycolysis to continue. Thus, fermentation regenerate more NAD+ and only a few molecule of ATP.

Bias can occur in sampling. bias refers to

Ira Lisetskai [31]

Bias can happen in sampling. The propensity of a sample statistic to systematically under- or over-approximate a population is referred to as bias.

To add, in statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population are less likely to be included than others.

The following are some types of biases in Statistics:

Selection bias includes individuals being more likely to be chosen for study than others, biasing the sample. This can also be termed Berksonian bias

In statistical hypothesis testing, a test is said to be unbiased if for some alpha level (between 0 and 1), the probability the null is not accepted is less than or equal to the alpha level for the entire parameter space defined by the null hypothesis, while the probability the null is rejected is greater than or equal to the alpha level for the entire criterion space interpreted by the alternate hypothesis.

Why are scientists warning that exclusively growing this mutant type by asexual reproduction presents a serious disadvantage?

Alla [95]

Answer:

Asexual reproduction can be described as a process in which daughter cells are produced which are 100% identical to the parent cells. Unlike the process of sexual reproduction, no recombination occurs in asexual reproduction. Hence, no variability is produced when organisms reproduce by this method.

As there will be lack of variability in asexual reproduction, the whole of the particular species might become endangered or extinct due to a disease or due to other factors like pests.
