Fill half their plate with fruits and vegetables
Answer:B---You will need to hold your head completely still during the examination
Explanation:
A CT scan of the brain is a diagnostic imaging procedure that uses special X-rays measurements to produce cross sectional images of the brain so as to provide an extra detailed information or data about brain tissue and structure concerning issues related to injuries or diseases of the brain.
During a brain CT, the X-ray beam moves in a circle around the body,and the scanner of the Ct SCAN xray starts to rotate around the body detecting the marked brain's tissues and then transmits the data to the computer. The computer will transmit the data fed into it into an image containing information that can interpreted by the radiologist.
One important procedure amongst others is to remain very still during the procedure so as to allow the right view to be captured by the scanner.
One possibility is that they broke a bone in their ankle, but there are probably others.
The main difference between a fruit and vegetable is what part of the plant it comes from.
A fruit is scientifically defined as “the mature ovary of a flowering plant that is edible.” The fruit is the ovary, the seed or seeds it encloses, and any parts associated with the ovary.
There is no precise/scientific definition for vegetable, but the basic definition is “the edible root, tuber, leaf, stem, seed or flower of a plant.” A vegetable is a plant or that part of a plant which is edible, and does not necessarily have a role in the plants reproductive cycle.
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.
