Answer:
Leave only the essential warning lights activated.
Explanation:
Emergency medical technician (EMT) is used for the health care providers in case of the emergency medical services. They respond quickly and provide medical facilities at the emergency situation.
During the accident, EMT can be called for the medical services. They can provide first aid, medicine to the injured individuals. The EMT leave only the important warning light at the accident spot so that other people may get alert about the situation.
Thus, the correct answer is option (D).
If the cell membrane did not allow nutrients to pass through, the nucleus would be unable to send out instructions. Additionally, the mitochondria is the powerhouse of the cell.
oh hello again, it is mentally impossible (unless you suffer severe brain/head injury) to forget everyone and everything. your brain is constantly taking mental photos of everyone and everything you see, you will always recognize someone you have seen a while ago even if its by the slightest. That probably wasn't my best wording, my brain is fried ☠.
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.
Ubuntu's solution to social problems is to understand that people cannot survive by simply obeying laws created or imposed by the state. Its solution to social order rests upon individual acceptance of common community norms and goals.
Through its emphasis on humanity, compassion and social responsibility, Ubuntu (“I am because we are”) has the potential to reduce conflicts between individual rights and public health, and might help governments gain community support for actions in emergencies.

Anecdotal evidence suggests that increased dependence on natural resources of families affected by HIV/AIDS will lead to overharvesting of certain species and decreased biodiversity and ecosystem health.
