Answer:

A. Scientists had to convert information from amino acids to nucleic acids.

Explanation:

Reverse transcriptase is the enzyme that can form the DNA copies of RNA template. The DNA formed by using RNA as template is called as cDNA. Since the amino acid sequence of insulin was known, the respective mRNA was synthesized using genetic codes. The mRNA was copied into its cDNA copy using reverse transcriptase enzyme. This was followed in insertion of insulin gene into the plasmid vector. hence,  using reverse transcriptase necessary for production of insulin gene from its known amino acid sequence.

a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the
castortr0y [4]

Question:

Which of the following is an incorrect statement about the regulation of populations?

Answer:

b. Density-independent factors have an increasingly greater effect as a population's density increases.

Explanation:

A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.

Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.

Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.

Mathematically, the population change equation is given by the formula;

Population Change = (Natality - Mortality) + (Immigration - Emigration)

Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;

I. Density-independent factors.

II. Density-dependent factors.

Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.

Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
