Answer:

Her minimum height must be 5'5" and her minimum weight must be 150 lb

Explanation:

The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.

Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.

The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.

If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population
s344n2d4d5 [400]

<u>Given:</u>

Present population of bison = 3652

Maximum growth rate = 0.28

<u>To find:</u>

The population of bison after one year.

<u>Solution:</u>

The future population can be calculated with the help of the following formula,

P_F=P_P\times(1+r)^n

where P_F is the future population, P_P is the present population, r is the growth rate and n is the number of years.

On substituting the given values in the formula we get,

\Rightarrow P_F=3652\times(1+0.28)^1

\Rightarrow P_F=3652\times1.28\rightarrow4674.56\approx4675

Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.

There is an algal bloom in a bay in a populated area. As the leading marine biologist in the area, what is the most important th
k0ka [10]

Answer:

evacuate all wildlife from the bay

Explanation:

Algal bloom is a term used to describe the excessive growth of algae species in a water body. This excessive growth or proliferation is as a result of the exposure to nutrient in form of pollutants, a process called Eutrophication.

However, the presence of an algal bloom indicates the pollution of that water body, which will result in the degradation of the pollutants by bacteria. As bacteria acts on the pollutants in the water body, they excessively use the dissolved oxygen of the water body, hence, drastically reducing the oxygen levels of the water. This possess a great threat to aerobic wildlife in the water, which could die as a result of suffocation or anorexia.

Hence, the most important thing to do in a case of noticing an algal bloom in a bay is to evacuate all wildlife from the bay in order to prevent mass death.

kotegsom [21]

Answer:

At the end of<u> telophase II </u>and cytokinesis, there are four haploid cells.cells.

Explanation:

During telophase II the sister chromosomes separate from each other and move to the opposite ends of the cell. Once that the chromosomes are in the opposite ends, the cytokinesis starts, this is the division of the cytoplasm that will give two daughter haploid cells.

We have to remember that there will be four haploid cells because there are two cells, which are the result of meiosis I, that will go into meiosis II to give these four daughters haploid cells. Also, the phases in meiosis I and II are very similar. Both of them have prophase, metaphase, anaphase, and telophase.
