Dominant and recessive genes effect on phenotype

marysya [2.9K]

Dominant is the first gene variant in a phenotype from the two alleles of a gene and recessive has effect on the third allele of a phenotype.

Explanation:

The genetic phenomenon of masking of chromosome with one variant of allele or predominating the impact of one gene on its chromosomal copy is Dominance. In this phenomenon the first variant of gene is known as ‘dominant’ and the second one is ‘recessive’.

This phenomenon is not inherited by phenotype, it has a relative effect on two alleles of a gene where one is dominant on other and the recessive is on third allele. Dominant allele has functional protein but recessive does not have it.

caffeine increases activity not only in the brain but also in the branch of the nervous system serving the body. this branch is

g100num [7]

The appropriate response is peripheral.

<h3>What exactly does being nervous mean?</h3>

Expressing or demonstrating worry, apprehension, or concern I get anxious whenever I have to give a speech.
A sudden feeling of dread or panic She detests operating a vehicle.
Consisting of, involving, or comprising nerves or nerve cells.

<h3>What functions does the nervous system perform?</h3>

Your nervous system uses neurons, which are specialized cells, to send impulses and messages throughout your body. Your muscles, organs, glands, skin, and brain all send and receive electrical signals. The communications allow you to move your limbs and feel things like pain.

Consider the following geometric solids a sphere with a ratio of surface area to volume equal to 0.08 M negative one a right cir

azamat

Options:

A. The rate of diffusion would be the same for the two models.

B. The rate of diffusion would be faster for the right cylinder.

C. The rate of diffusion would be slower for the right cylinder.

D. The rate of diffusion would be faster for the sphere.

Answers:

The rate of diffusion would be faster for the right cylinder. Thus, the correct option is B.

To begin with, we must comprehend how the ratio of surface area to volume affects the rate of diffusion.

When comparing the ratio of surface area to volume, a body with a larger surface area will have a higher rate of diffusion than a body with a smaller surface area. It can be expressed mathematically as:

V∝ R (whereas v is the diffusion rate and r is the surface area to volume ratio)

The answer to the question's surface area to volume ratio for spheres is given 0.8m⁻1

For a right circular cylinder, the surface area to volume ratio is provided is 2.1 M.

The right circular cylinder has a larger ratio, hence it is obvious that the right circular cylinder will have a higher rate of diffusion because the rate of diffusion is directly related to the surface area to volume ratio.

which of the following levels of protein organization shows the complete 3D arrangement of the polypeptide chain

kherson [118]

Proteins are the macromolecules made of hundreds of amino acids. Proteins are most varied class of biological molecules and show the greatest variety of structures. Many have detailed three-dimensional folding patterns that result in a compact form, but others do not fold up at all and they are in random conformations. The function of proteins depends on their structure.

The secondary structure of protein fold together to form the 3D arrangement of a polypeptide chain that results into Tertiary structure which is a functional protein.
