The gene pool gets smaller in each generation, which is the characteristic of a population that is in Hardy- Weinberg equilibrium. The correct option is A.

The gene pool encompasses all of a species' genetic diversity. The gene pool's size can change. When organisms have mutations that are passed down to the next generation, the gene pool expands.

When all of the organisms carrying a particular allele die before having offspring, the gene pool shrinks.

Thus, the correct option is A.

Answer:

B

Explanation:

Answer:

Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.

Explanation:

Immunity is the ability of an animal to resist infection.

There are two types of immunity in the body; INNATE OR INHERITED IMMUNITY AND ACQUIRED IMMUNITY. Inherited immunity it is the type of immunity that one is born with. It is passed from parent to offspring.

Acquired immunity is immunity to particular infections that is not inherited but has developed in the animal's life as it interacts with its environment. Acquired immunity can develop naturally in which case it is called NATURAL ACQUIRED IMMUNITY OR ARTIFICALLY.  

ACTIVE IMMUNITY is the form of acquired immunity in which the body produces its OWN antibodies against infections. While PASSIVE IMMUNITY is the form of acquired immunity in which an individual is PROTECTED AGAINST INFECTION BY RECEIVING ANTIBODIES.  

NATURAL ACQUIRED IMMUNITY

when attacked by the same pathogens again, they don't became seriously ill. this is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens. This is known as NATURAL ACTIVE ACQUIRED IMMUNITY. It develops when one recovers from an infection.

During pregnancy, the mother passes antibodies across the placenta to the foetus. At birth the baby gets antibodies from the mother through breast milk. This is natural passive acquired immunity.

When a purple flower with a genotype PP is crossed with a white flower that has a genotype of pp. The phenotype of the offspring would be Purple (Pp).

Genotype may be defined as the ultimate combination of the alleles of those genes which are selected for specific studies.

The phenotype of the offspring would be Purple (Pp). This is because the allele of the purple phenotype is dominant over the allele of the white phenotype. That is P > p.

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis.

Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.

A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane. The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.
