IRISSAK [1]

Because of high blood pressure or from injury to the glomeruli.

<h3>Why do proteins typically not appear in urine samples?</h3>

There is protein in the blood, but healthy kidneys should only remove very little amounts (traces) of it through the filters into the urine (glomeruli). Protein loss in the urine is not typical.

<h3>What are the proteins found in typical urine?</h3>

You typically have a very small amount of protein in your urine. If your urine contains a lot of protein (proteinuria), your kidneys may be the source of the issue. Your kidneys are a set of organs that purify surplus water and waste from your blood to create urine.

insens350 [35]

Answer:

The correct option is <em>B) ultraviolet region, especially below a wavelength of 320 nm.</em>

Explanation:

Ultraviolet light carries an enormous amount of energy in it. It is invisible to the human eye. When UV light with enormous energy and wavelength lesser than 320nm, hits the DNA, it causes changes in the structure of the DNA. Mostly, it affects the thymine nitrogenous base regions and forms pyrimidine dimers. The structure of the DNA changes on all the sites where dimers form and hence, they cannot be properly transcribed.
