QveST [7]

Answer:

D. digestive and reproductive

Explanation:

Living system can be defined as the internal systems of organisms and how materials circulate within organisms.

Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.

Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.

Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc.

When a woman is pregnant, the part of her body systems that are involved in providing needed nutrients to her unborn child are the digestive and reproductive systems. During pregnancy, it is very important that mothers have good nutrition so as to keep themselves and their baby healthy.

The placenta which is normally formed during the embryonic stage, helps to take water, oxygen and nutrients from the blood, filter out any harmful substance and then transports them to the unborn baby through his or her umbilical cord.

Accurately 3 different ways that antiretroviral drugs can prevent virus formation.
natta225 [31]

Answer:

Three different ways in which antiretroviral drugs can prevent the formation of new viruses are:

  1. Inhibiting the reverse transcriptase enzyme in both nucleoside analogues and non-nucleoside analogues.
  2. Enzymatic inhibition of integrase enzymes.
  3. 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:

  1. <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>
  2. <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>
  3. <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.
