Answer:
Two different ways in which antiretroviral drugs can prevent the formation of new viruses are:
- Inhibiting the reverse transcriptase enzyme in both nucleoside analogues and non-nucleoside analogues.
- Enzymatic inhibition of integrase enzymes.
Explanation:
Antiretroviral drugs are those used for the treatment of human immunodeficiency virus (HIV) infection, making the effect of the virus on the host cell is less and preventing the development of AIDS.
This type of drug has been classified, according to their mechanism of action, being grouped into several families of drugs. Two different ways by which antiretroviral drugs can prevent the formation of virus are:
- <em><u>Inhibition of reverse transcriptase enzyme</u></em><em>: this enzyme is a DNA polymerase capable of forming single strand viral RNA by a process that is reverse to normal DNA to RNA transcription. Its inhibition prevents the formation of viral particles in the host cell. They are divided into nucleoside analogs and non-nucleoside analogs.</em>
- <em><u>Enzymatic Inhibition of Integrase enzymes</u></em><em>: this type of enzyme is contained in the virus, and is capable of causing a retrotranscribed DNA to integrate into the host cell's DNA so that viral replication occurs. Its inhibition prevents the replication process.</em>
The most effective treatments against HIV infection involve the use of two or more types of antiretroviral drugs.

Hello,
Answer to question 1:
It is very useful to increase your flexibility because it helps your body to move better and stay active. Also you will get less pain from moving a lot if you body stays in shape.
Answer to question 2: Increased flexibility in sports is relay important. It helps the person to stay active and work his/her body. Ex. If your playing foot ball, you know all the plays in the book. Your really good and you work out. Now you stop playing for 5 years. Mostly if you trying foot ball again you will not play the same from 5 years ago.
So Flexibility is very important in everyone daily life to stay healthy and strong.
Hope this helps.
Kyle is definetlyunderweight you can tell even before doing the math. If he is 6 foot and weighs 125 LBS this man needs to see a doctor because he should be atleast 175 which would give him a BMI of 23.7
<span>The choices can be found elsewhere and as follows:
</span><span>A) REM; Stage 1
B) Stage 1; REM
C) REM; Stage 2
D) Stage 2; REM
E) REM; Stage 4
</span><span>
I believe the correct answer is option E. Paradoxical sleep is to slow-wave sleep as REM sleep is to stage 4 sleep. Hope this answers the question.</span>
