pishuonlain [190]

You have a population in hardy-Weinberg equilibrium for the m and n alleles. These alleles are codominant. Allele frequency of m is 0. 4. 0.48 is the frequency of heterozygotes in the population.

An allele frequency has been computed by dividing the total quantity of copies of each of the alleles at that specific genetic location in the population by the number of points of time the allele of interest has been observed in a population.

The frequency of each genotype is typically calculated by dividing the population's total count of individuals by the number of people who have that genotype.

True or false: The heart myocardium is nourished primarily through the diffusion of nutrients from the blood in the heart chambe

lesya692 [45]

It is false that the heart myocardium is nourished primarily through the diffusion of nutrients from the blood in the heart chambers.

<h3>Heart Myocardium?</h3>

Heart Myocardium is also called Cardiac muscle is a specialized type of muscle tissue that cover the heart. The cardiac muscle ontracts and relaxes nvoluntarily and it help to keep the heart pumping blood to the body.

Therefore, It is false that the heart myocardium is nourished primarily through the diffusion of nutrients from the blood in the heart chambers because it is nourished by blood flow through the coronary arteries.

What is the accumulation of differences between species or populations?

FromTheMoon [43]

Answer: Divergence evolution or divergent selection

Explanation:

The divergent evolution/divergent selection can be defined as the process of accumulation of differences between the related populations lies within the species. This process leads to speciation.

This occurs when the two populations of the same species get separated by a geographic barrier. The separated members of the same species experience different selective pressure that are responsible for adaptation in the new environment.

b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t

saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.
