To obtain a scan using the positron emission tomography technique, a patient is injected with (or ingests) a low and harmless dose of a short-lived radioactive glucose.
<h3>
What is Positron emission tomography?</h3>
This refers to a type of imaging technique which employs the use of radioactive substances in other to measure the metabolic activity of the cells of body tissues.
A scan using this technique is obtained by injecting the patient with a low and harmless dose of a short-lived radioactive glucose so that a picture of where the glucose being used in the body is visible and helps to detect cancerous cells etc.

Answer:
Different types of intercellular junctions, including plasmodesmata, tight junctions, gap junctions, and desmosomes. Plasmodesmata (singular form: plasmodesma) are intercellular organelles found only in plant and algal cells. Tight junctions are located within our body's epithelia. Epithelia is the plural of epithelium. Epithelium is a word that refers to the covering of the body's internal and external surfaces. This includes organs (such as skin), blood vessels, and cavities. Gap junctions are found in many places throughout the body. This includes epithelia, which are the coverings of body surfaces, as well as nerves, cardiac (heart) muscle, and smooth muscle (such as that of the intestines). Desmosomes are prominently found in cardiac muscle
The discovery of microRNAs (miRNAs) is one of the major scientific breakthroughs in recent years and has revolutionized the way we look at gene regulation.
<h3>
What is MicroRNAs ?</h3>
microRNA is the name of a family of molecules that helps cells control the kinds and amounts of proteins they make
- That is, cells use microRNA to help control gene expression. Molecules of microRNA are found in cells and in the bloodstream.
- The miRNA functions as a guide by base-pairing with target mRNA to negatively regulate its expression.

Answer:
<u>Ethanol prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u>
Explanation:
Ethylene glycol is an organic compound usually used in antifreeze solutions, solvents and cleaners.
It is abused during self-destruction and accidental intakes.
<u>In the body, ethylene glycol is acted upon by alcohol dehydrogenase and is converted into glycolate and oxalate.</u>
Glycolate and oxalate are both nephrotoxic/ kidney damaging substances. Oxalate precipitates calcium oxalate stones in the kidney. Ethylene glycol poisoning also causes high anion gap metabolic acidosis.
In order to prevent ethylene glycol poisoning, the patient is infused with ethanol, ethanol <u>prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u> In this way, ethylene glycol is not metabolized and the formation of nephrotoxic substances is prevented. Alcohol dehydrogenase instead reacts with ethanol to form acetaldehyde.
