Answer:

involves injecting the body with specific medication

Explanation:

Vaccination is a versatile and effective methodology for preventing diseases caused by exposure to harmful bacterial and viral infectious agents. Literally, vaccination refers to the administration of medical preparations that help the body to produce immunity against infectious diseases. Vaccines are used to prevent outbreaks caused by infectious diseases. Even under optimal conditions, vaccination is not always effective in preventing disease transmission, because the immune system of each organism may react in a different manner to the same vaccination (even to the same dose). However, vaccination is always encouraged to prevent the spread of infectious diseases. Although there are many vaccines that target age groups, there are others that can be applied to different ages.

1. What is the advantage of using a patient's stem cells to make organ to replace the patient's failed
motikmotik

Answer:

Answered below

Explanation:

Collecting a patient's stem cells and using them for their treatment is known referred to as autologous stem cell transplantation. In autologous stem cell transplantation, stem cells are harvested in the patient's bloodstream or the bone marrow and used to treat or grow organs for the patient.

Using stem cells harvested from your own body is advantageous over stem cells collected from a donor. This is because the case of incompatibility is eliminated. There is also less risk of rejection of organ or graft versus host disorder, where the donor cells attack the host cells thinking they are foreign bodies.

There are fewer side effects and quicker engraftment and therefore quicker recovery.

There are 100 cats in a population that follows hardy-weinberg conditions. 4 cats display a recessive white coat color. how many
mr Goodwill [35]

We know that Hardy-Weinberg conditions include the following equations:


p^{2}+2pq+ q^{2}=1


where p+q=1


And where p = dominant, and q = recessive; this means that p^{2} is equal to the homozygous dominant, 2pq is the heterozygous, and q^{2} is the homozygous recessive .


So we have 100 total cats, with 4 having the recessive white coat color. That means we have a ratio of \frac{4}{100} or 0.04. Let that equal our q^{2} value.


So when we solve for q, we get:


q^{2}=0.04

q=\sqrt{0.04} =0.2


Now that we have our q value, we can use the other equation to find p:


p+q=1


p+0.2=1


p=0.8


So then we can solve for our heterozygous population:


2pq=2(0.8)(0.2)=0.32


This is the ratio of the population. So we then multiply this number by 100 to get the number of cats that are heterozygous:


0.32*100=32cats


So now we know that there are 32 heterozygous cats in the population.

Negative feedback: If the body temperature is high, the rate of perspiration (sweat) should
s344n2d4d5 [400]

Answer:

I believe it would decrease

Explanation:

The high temperature will be detected by sensors—primarily nerve cells with endings in your skin and brain—and relayed to a temperature-regulatory control center in your brain. The control center will process the information and activate effectors—such as the sweat glands—whose job is to oppose the stimulus by bringing body temperature down.
