Answer: The correct option is C. Nucleus.

Nucleus is a specialized membrane bound organelle, which is localized in the center of eukaryotic cells. This organelle contains directions for the growth of cell and reproduction.

It contains the genetic material of the living organisms, which is DNA ( deoxyribonucleic acid). Cell cycle is necessary for the cellular growth and reproduction. The direction for this is given by the DNA as during cell cycle, growth and division of the cell takes place. Thus, one cell is converted into two cells.

Thus, nucleus contains direction for the cell growth and reproduction.

Answer:

This is an example of "Disruptive selection".

Explanation:

Disruptive selection occurs when selective pressure favor homozygous. In equilibrium, the two alleles might be present or one of them might be lost. If an environment has two extremes, then in these environments, both alleles are presented in homozygous.

The disruptive selection causes an increase in the two types of extreme phenotypes over the intermediate forms. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, or predation.

Populations show two favored extreme phenotypes and a few individuals in the middle. Individuals who survive best are the ones who have traits on the extremes forms. Individuals in the middle are not successful at survival or reproduction.

Color is very important when it comes to camouflage. Dark green caterpillars that live in dark foliage and light green caterpillars that live in light foliage can hide from predators more effectively and will live the longest. Intermediate colored green caterpillars that don't camouflage or blend into either will be eaten more quickly.

Answer:

This composition of nucleotide given in the question do not obey the chargaff"s rule.

Explanation:

According to chargaff"s rule the total number of purine bases will be same to the total number of pyrimidine bases that is

Adenine+Guanine=Thymine+Cytosine

But here the above quation is not maintained because according to the question A+G=49%

and T+C = 51%.

Such DNA is replicated by rolling circle model.
