The answer is C. large changes in allele frequencies can occur in a short time.
Genetic drift is a change in the frequency of alleles in a population as a result of random sampling of organisms and it decreases genetic variation of the population. In specific circumstances, large and rapid changes in allele frequencies can occur in a short time. The smaller the population, the more susceptible it is to genetic drift.
The answer to this question is B
Based on the information in the table,
- the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
- the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.
<h3>What are enzymes?</h3>
Enzymes are organic catalysts that speed up the chemical reactions occurring in the body.
Enzymes are very essential in most metabolic reactions occurring in the body.
The deficiency or inactivity of an enzyme in the body will lead to an accumulation of the substrate on which the enzyme acts on.
Based on the information in the table,
- the enzyme which is not functioning in the strain of mold is Enzyme Z which is responsible for the conversion of Citrulline to Arginine.
- the substance that would begin accumulating in the mold is Citrulline since it is not being converted to Arginine.
in conclusion, enzymes are important for biochemical reactions.

Answer:
Firstly, the partial pressure of nitrogen (78%) is crucial to breathing purposes. Without this pressure, the lungs will burst and animals cannot survive.
Secondly, nitrogen is required for the formation of amino acids (building blocks of proteins) and other organic compounds that are necessary for the survival of living organisms. Principally, in the atmosphere, nitrogen is present in the form of molecular nitrogen (N2). N2 is fixed by nitrogen-fixing bacteria that form nitrates and nitrites. These molecules are then used in biochemical processes to produce proteins (amino acids) and other organic compounds. In the absence of nitrogen, these processes could become seize of limited significantly thus affecting life overall.
Thirdly, nitrogen and its derivatives act as greenhouse gases that maintain the Earth's temperature within a range that supports life. Yes, the increased abundance of nitrous oxides is not good because of acid rain and other issues, however, still, the presence of nitrogen is important for life on this planet.
