Answer:
<h2>True</h2>
Explanation:
1 .Reverse transcriptase (RT) is an RNA-dependent DNA polymerase enzyme which makes DNA from RNA..
2. RT makes double-stranded DNA molecules from ssRNA ( single stranded RNA) molecule using it as a template.
3. Retroviruses like HIV contain Reverse transcpritase (RT) enzyme, which uses the RNA molecule as template and make DNA from it and after that, virus make multiple copies of itself.
4. Reverse transcriptase enzyme make DNA reverse transcrptionally from RNA the process known as RNA dependent DNA polymerase.
5. It was first discovered in retroviruses.
Answer:
Yes, there is a need to assure the client that this is a normal reaction.
Explanation:
In the given case, it is the duty of a nurse to assure the patient that swelling takes place while performing intradermal vaccination. As with the administration of disease-specific antigens, the injected area inflames that generally takes place due to the development of antibodies against the presented antigens.
Thus, both the patient and the nurse need to be calm in such a situation and should leave the swelling open so that it can get heal by itself. In case, if one applies ice packs or rubs the affected area, it can enhance the condition and may result in more issues.
Recall the endosymbiosis hypothesis and recall endosymbiosis. Remember that the very first cell was a prokaryotic cell. Which engulfed chloroplast precursors and mitochondria. We all come from these cells. And how we evolved over time shows the relationship. I'm a bio major hope I helped
The choices can be found elsewhere and as follows:
<span>a) mixture called a suspension
b) mixture called a solution
c) solution and suspension
d) mixture only.

I believe the answer is option B. If you stir salt into boiling water, you produce a mixture called a solution. Hope this answers the question. Have a nice day.
Answer:
Presence of papillary muscles
Explanation:
- Papillary muscles are structural components of the ventricles.
- They are attached to the cusps of the mitral and tricuspid valves through connective tissue strings known as the cordinae tendeneae (heart strings).
- These muscles prevent the prolaspse of these valves during ventricular systole.
- Although they differ in number i.e. two in left and three in right ventricle, papillary muscles are present in both ventricles.
