Answer:

B. Mutation; C. Random genetic drift; D. Migration; F. Natural selection

Explanation:

B. Mutation:  Mutations resulting from substitution, addition or deletions of a nucleotide in a sequence can alter the gene. This can be carried over a population and may be have deleterious effects or increase fitness in a gene.

C. Random genetic drift: It is a change in allele frequency that occurs by chance, usually in a small population and is carried over generations.

D. Migration: Involves the flow of a gene in or out of a population, and this modifies the allele frequency.

F. Natural selection: When fitness-promoting alleles are favored and carried over to the next generation.

SCORPION-xisa [38]
The sugar that is produced in photosynthesis is a glucose.
- Glucose can be used to provide energy for cellular activity.
- Excess of glucose is transformed into starch. Starch is transported into storage organs.
- Glucose can be transformed into cellulose, pectin, and chitin. These molecules are structural materials for the cell walls.
- Fats and amino acids can be formed from glucose. These molecules can serve as structural materials or can be stored.

Explain how the shape of a protein molecules can affect its function
kherson [118]

Solution:

The function of a protein is determined by its shape.

The shape of a protein is determined by its primary structure (sequence of amino acids).

The sequence of amino acids in a protein is determined by the sequence of nucleotides in the gene (DNA) encoding it.

IrinaK [193]

Answer:

A molecule with 32 percent or more amount of Cytosine.

Explanation:

DNA is the genetic material of all the living organism but in few viruses, RNA can also acts as the genetic material. DNA contain nitrogenous bases ( adenine, guanine, thymine and cytosine), deoxyribose pentose sugar and the phosphate bond.

The triple bond is more stable than the double bond. Since, cytosine and guanine shows triple hydrogen bonding and shows more stability. The DNA molecule that contains more residues of guanine and cytosine is stable than the molecule containing adenine and thymine residues.

Thus, the answer is molecule with 32 percent or more amount of Cytosine.

When growing, as a cell gets bigger, what happens to its surface area to volume ratio?
marysya [2.9K]

<u>Answer</u>:

Surface area to volume ratio decreases.

<u>Explanation</u>:

When the cell enlarges beyond its capacity, it fails to supply enough material that can cross the membrane sooner so as to occupy the cellular volume. Hence the diffusion rate also decreases so as the ratio. The cell carry out its various functions to sustain through diffusion when diffusion rate is low it will ultimately affect the ratio. Bigger size affects the diffusion of the material to the out of the cell. as we know the diffusion occurs across the surface of the cell.
