The heterozygous birds phenotype would therefore be black and white because both parent genes are dominant so they would be fully expressed,none would overpower the other(no dominant or recessive) this is known as Codominance and and example of this is with the blood types.

What is meant by the statement "Evolution may proceed along 'genetic lines of least resistance'"?
Ivan

Answer:

C. Characters with little genetic variation will constrain the rate of natural selection

Explanation:

Natural selection can have an effect only as long as there are variations on characters on which it can select upon. Genetic variation is independent of the environment or the needs that a species may have to become better adapted to its changing environment. In other words, genetic mutations are the raw material on which natural selection can work. If there is a low rate for mutations to occur, then natural selection will proceed at a slow pace. The opposite is also true. Since mutation rate may be more frequent at some locations in a gene than at others, it can be predicted that the characters coded in that gene location will be more likely to be affected by natural selection and therefore what phenotype may be molded by natural selection.

Humans use many chemical substances for farming that consequently affect biodiversity. These compounds, which are rich in nitrog
posledela

Answer:

algal growth due to eutrophication

Explaination:

Eutrophication is where these nutrient rich compounds mix with nearby water sources and promote the growth of large amounts of algae. Algae go through respiration and take up the dissolved O2 in water which causes these areas to experience low O2 levels. Everything needs O2 to survive thus nearby organisms and plants die out creating dead zones.

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.
