Answer : The correct answer is -

A.)Will remain stable from generation to generation.

According to Hardy-Weinberg Principle, the frequency of allele and genotype in a particular population remains stable/constant from generation to generation (if evolutionary influences are not present).

There are following assumptions of this principle -

1) Large size of population.

2) There should be no gene flow between populations (either due to migration or gamete transfer).

3) There should be no mutations in the population.

4) Random mating should occur between individuals.

5) No natural selection should operate on the population.

Thus, option A) is the right answer.

______________ is a statistical procedure that can be used to identify clusters of behaviors that are related to a trait.

Mamont248 [21]

Answer:

Factor Analysis

Explanation:

Factor Analysis is a statistical procedure that can be used to identify clusters of behaviors (such as verbal skills, intelligence) that are related to a trait.

Factor analysis helps to accumulate a lot of data in many variables into a few variables which can be used for further analysis or study. The aim of factor analysis is to aggregate individual behaviors into a minimized number of factors.

The diagram shows a type of lipid.

Ket [755]

Answer:

Explanation

The structure of saturated fats are not flexible unlike unsaturated fats. ALso in the diagram, there are no double bonds which are present in unsaturated lipids, eliminating A and B. Triglycerides have 3 fatty acids shown with 3 carbons that are connected with long bonds unlike phospholipids that has 2 fatty acids. Therefore the answer is E.

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base

Georgia [21]

Answer:

The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.

Explanation:

In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.

In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.

For the other options:

Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs.

Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete.
Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.

ICE Princess25 [194]

Answer:

The correct answer is A.

Explanation:

A mutagen changes the level of mutations that occur in the DNA either by affecting it physically or chemically. This helps researchers create different organisms with altered phenotypes according to what the research needs so that the genes can be investigated further under a controlled environment.

So the answer is A.

I hope this helps.
