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.
To protect the important information inside the computer is to ensure that the computer has an active antivirus and firewall.
Second, another important procedure is not to get into different foreign sites which I can get viruses or malware that are capable of corrupting the computer and injecting programs that would cause problems with the applications and documents.
Answer:
Cardiovascular Endurance ⇒ Running
Running trains the cardiovascular system as it requires continuous oxygen supply to the muscles.
Muscle Strength ⇒ Lifting weights
Lifting weights builds muscle strength by as muscles get stronger from lifting heavier objects.
Muscle Endurance ⇒ Light Hand Weights
Using light hand weights such as hand grips build endurance in the muscles as they can be exercised with for longer.
Flexibility ⇒ Stretching
Stretching loosens up the joints which leads to increased flexibility.
Body Composition ⇒ Exercising Regularly
By exercising regularly, one can target all or at least most parts of the body which will lead to an improved body composition.
Intravenous mixtures are prepared in sterile conditions. They are infusions that are given through injections and syringes. It is important to keep the preparation sterile as it is directly injected to the veins which is a faster way to assimilate to the system. Thereby, proper preparations must be applied. ANswer is D.
