New cells with identical DNA are created through cell division.

Explanation:

5 A prokaryotic cell is 5.0 um in length. A virus particle is 300 nm in length. How many times larger is the prokaryotic cell compared to the virus particle?
A 2
B 17
C 60
D 167​

Answers

The prokaryotic cell is 17 times larger as compared to the virus particle.

Both values first need to be converted to the same unit.

5.0 um = 5.0 x [tex]10^-^6[/tex] m

300 nm = 3.0 x [tex]10^-^7[/tex] m

Dividing both values:

   5.0 x [tex]10^-^6[/tex] m/3.0 x [tex]10^-^7[/tex] m

                        = 16.667

Hence, the prokaryotic cell is approximately 17 times bigger than the virus particle.

which is not involved with an inflammatory Response
A. Fever - increased temperature
B. Slowed blood flow
C. White blood cells move to the area of infected
D. inflammation in area

Answers

Slowed blood flow is not an inflammatory response.
Reasoning: a fever is caused by the body trying to kill off any unwanted pathogens with the heat. This is an inflammatory response to the body being infected.
White blood cells move to the infected area in an attempt to kill any pathogens. Since white blood cells are mainly meant to help kill pathogens, it is an inflammatory response to send white blood cells to kill the pathogen.
Lastly, inflammation is caused by the body trying to rid the infected area of the pathogens. Similar to the name “inflammatory”, the body will often cause inflammation in an attempt to get rid of any unwanted pathogens in the body.

This is an inflammatory reaction to an infection in the body. Option D is correct.

What is the inflammatory response?

When tissues are harmed by toxins, germs, trauma, heat, or any other cause, the inflammatory response (inflammation) ensues. A fever is induced by the body's attempt to destroy any infections with heat.

Histamine, bradykinin, and prostaglandins are among the substances released by injured cells. Because of these substances, blood vessels leak fluid into the tissues, producing swelling.

White blood cells migrate to the affected location to destroy any germs. Because white blood cells are primarily intended to aid in the killing of infections, sending white blood cells to destroy the pathogen is an inflammatory reaction.

Finally, inflammation results from the body's attempt to cleanse the contaminated region of microorganisms. Similar to the label “inflammatory,” the body will frequently create inflammation in an attempt to cleanse the body of any undesirable infections.

Therefore, option D is correct.

source of the pollution

Answers

Answer:

Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. It can still spread and harm living creatures and destroy their environments.

Explanation:

Air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.

What is Pollution?

Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.

Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.

Answers

Answer:

50%

Explanation:

trust me because the heterozygous is so weird but I know this.

In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.

What will be produced in turkeys a dominant gene?

In turkeys a dominant gene, R, produces the familiar bronze color; its recessive allele, r, results in red. Another dominant gene, H, results in normal feathers; its recessive allele, h, produces feathers without webbing, so that they resemble tufts of hairs.

Two bronze turkeys with normal feathers were mated, and their offspring consisted of eight bronze with normal feathers, three bronze with hairy feathers, two red with normal feathers, and one red with hairy feathers.

Since, this offspring received a recessive red, r, allele from each parent and a recessive hairy, h, allele from each parent, both parents must heterozygous for both characters: RrHh.

Therefore, In turkeys the allele for brown feather is dominant to the allele for a yellow feather. if two heterozygous turkeys mate and produce offspring, than the probability of an individual offspring having yellow feather is 50%. Thus, option A is correct.

The basic pattern of blood flow from the lungs to the rest of the body is: pulmonary vein; left atrium; left ventricle; aorta. The option (B) is correct.

What are pulmonary vessels?

Pulmonary veins are blood vessels that carry oxygen-rich blood from your lungs to your heart. Your pulmonary veins are part of your body's pulmonary circuit. This is a system of blood vessels that moves blood between your heart and your lungs. This circuit also includes your pulmonary arteries.

For the exchange of gases to occur effectively, the lungs require a dual vascular supply known as pulmonary and systemic circulations. The pulmonary circulation is responsible for bringing deoxygenated blood from the body to the lungs for gaseous exchange and then returning oxygenated blood to the heart.

There are 4 total pulmonary veins—with 2 pulmonary veins coming from each lung, left and right—that empty into the left atrium of the heart.
