Answer:
Three 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.
- Inhibiting entry by antagonizing CCR5 co-receptors.
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. Three 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>
- <em><u>Entry inhibitors or antagonists CCR5 co-receptors</u></em><em>: CCr5 is a membrane protein, found on the surface of CD4 T lymphocytes, which facilitates the entry of the virus into the cell. The drug acts as a competitive inhibitor of the viral particle, preventing the entry and infection of the host cell.</em>
The most effective treatments against HIV infection involve the use of two or more types of antiretroviral drugs.
Answer:
Gradient.
Explanation:
Psychology may be defined as the field of biology that mainly deals with the study of the mind, behavior and social aspect of the individual. The one who is expertise in the psychology is known as psychologist.
The psychological gradient shows the unequal or difference in the physical pressure or chemical difference between the two points. This might also the difference in the mental activity and its response in the different actions like reading, writing and at its conclusion.
Thus, the answer is gradient.
Answer:
Why is a healthy body image important? Women with a positive body image are more likely to have good physical and mental health. Girls and women with negative thoughts and feelings about their bodies are more likely to develop certain mental health conditions, such as eating disorders and depression.
Explanation:
The Serous Membrane is known to have layers of simple squamous epithelium. It occur in pairs because by pairing, it helps the serious membrane to perform its function as the two moist layers make it even easier for organs to move without friction.
- The Serous Membrane as a layer of simple squamous epithelium on a thin layer of areolar connective tissue. It often occur in pairs called parietal and visceral layer.
- The parietal layer is wall layer and helps lines a some key portion of the wall of the ventral body cavity while the visceral layer helps to lines organs in the cavity
Conclusively, we can say parietal and visceral moist layer helps in create lines in the body cavity.
