The respiratory system is best described as The system which removes wastes from cells and exhales them from the body. The syste

mart [117]

Answer:

Option (4).

Explanation:

Respiratory system may be defined as the system involves in the exchange of gases between the tissue, lungs and the outside environment. The respiratory system involves nose, mouth, larynx, trachea, lungs, brochi, alevoli and alveolar ducts.

The oxygen is inhaled in the body and carbon dioxide is exhaled out from the body. The oxygen is transferred into the blood stream by binding of oxygen with hemoglobin. The oxygen is diffused in to body due to the partial pressure difference of oxygen and carbon dioxide.

Thus, the correct answer is option (4).

The transfusion reaction that arises from the mixing of incompatible blood types illustrates a/an _____.

adelina 88 [10]

The transfusion reaction that arises from the mixing of incompatible blood types illustrates a/an Hemolytic transfusion reaction.

<h3>Explain the Hemolytic transfusion reaction.</h3>

After receiving blood transfusions, a dangerous complication called a hemolytic transfusion response might develop. The response happens when the recipient's immune system kills the red blood cells that were donated during the transfusion. Red blood cell destruction is known as hemolysis. Other allergic transfusion responses exist that do not result in hemolysis.

<h3>What are the causes of Hemolytic transfusion reaction?</h3>

A high amount of incompatible plasma, which occurs less frequently, and the transfusion of incompatible red blood cells (RBCs) are the two most common causes of acute HTRs that happen during or within 24 hours following the delivery of a blood product. A subsequent immunological reaction to an antigen on the donor's RBCs results in delayed HTRs.

A) In the Dunker population, the frequency of IB allele is 0.3 and the frequency of i allele is 0.4. In the general population, the frequency of IB allele is 0.1 and the frequency of i allele is 0.5.

If:
$I^{A}$ - the frequency of IA allele
 $I^{B}$ - the frequency of IB allele
 $i$ - the frequency of i allele

Then:
 $I^{A} I^{A}$ + $I^{A} i$ - the frequency of individuals with A blood type
 $I^{B} I^{B}$ + $I^{B} i$ - the frequency of individuals with B blood type
 $ii$ - the frequency of individuals with O blood type

Let's first take a look on the Dunker population:
$I^{A} = 0.3$
$ii=0.16
$

Since there is only one possible genotype for O individuals - ii - the frequency of the allele i is square root of the frequency of O individuals:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.16}$
⇒ $i=0.4$

Now, we have the frequencies of two alleles ( $I^{A}$ and $i$ ). To calculate the frequency of $I^{B}$ allele, we will use the formula:
 $I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.3-0.4$
⇒ $I^{B} = 0.3$

Now, in the general population:
$I^{A} = 0.4$
$ii=0.25$

Similarly to the work for the Dunker population:
 $i= \sqrt{ii}$
⇒ $i = \sqrt{0.25}$
⇒ $i=0.5$

$I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.4-0.5$
⇒ $I^{B} = 0.1$


b) A founder effect is a result of geographical separation of a few individuals from the original population. Those founding individuals will form a new population. The Dunker population was not only geographically separated, but also genetically. The group interbreeding was present resulting in increasing those allele frequencies that were the most common in the founding population. In this case, the most individuals from the founding population had B blood type.

MA_775_DIABLO [31]

Answer:

the hormones produce a happy feeling.

Explanation:

The hormone the testosterone and endorphins are hormones that are produced by the endocrine system as a result of exercise and intense physical activities. These hormones are known as the happy hormones. They have the same effect as morphine would do on the body - they diminish the effect of pain and stress. The hormones do so by counteracting the effect of the stress hormone, cortsoids, that are produced in stressful situations. These hormones wear down the person emotionally and the person will be stressed. A person who exercises produces a happy feeling and healthy emotions. In addition, the hormone provides overall feelings of well-being and contribute to the manufacture of the T-lymphocytes thereby strengthening the immune system.
