Answer:
Option-
All of the given disorders and elements which causes them are correct.
- Proteins and other related minerals are required for the better functioning of the human body, as there can be a lot of complications faced by the over all system of the human body if there are low or inadequate level of proteins and minerals inside the human body.
Explanation:
While, the following disorders and causes of the protein and nutrients deficiency can be described as follows:
- Beriberi is rare in the United States.
- Alcohol-related thiamin deficiency is called Wernicke-Korsakoff syndrome
.
- Most adults get adequate riboflavin in their diets.
- Thiamin deficiency causes diarrhea, dermatitis, and dementia
.
- Since humans can synthesize niacin from tryptophan, they do not need to consume it.

The question is incomplete as it does not have the options which are:
I. only
I. and II. only
II. and III. only
I, II, and III.
Answer:
I, II, and III.
Explanation:
The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.
The natural selection can be explained by the phenotype produced in a population and that depends on the genes. The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.
Thus, I, II, and III are correct.
Restriction enzymes and or restriction endonucleases are involved at recognizing specific sequence of nucleotides and cutting or splicing them at appropriate regions to produce fragments that can either be sticky ends or blunt ends depending on where they cut and the nature of nucleotides involved within the fragments. They play an important role in genetic engineering, as geneticists can use them for placing into extra chromosomal information and or content of plasmids in certain bacteria, from other sources, for instance antibiotics, grow and or produce many individual colonies of bacteria, isolate them and one would have many sequences for instance that can code for an antibiotic that can be extracted and used further. Assuming the bacteria's plasmid can take in that sequence.
