Under normal conditions, the tubular load of glucose (the amount/min that filters into the kidney tubules) is approximately 125

djverab [1.8K]

Answer:

0mg/min

Explanation:

Glycosuria is a disorder in which glucose is excreted in the urine despite its normal or low blood concentration.

Urine contains very small amounts of glucose, as the proximal bypassed tubule reabsorbs virtually all of the glucose, but if the patient has hyperglycemia that exceeds the renal reabsorption threshold (160 to 180 mg / min), there will be glycosuria. For this reason, we can conclude that if a person has a tubular glucose load equal to 125 mg / min. The amount of glucose in the urine will be approximately 0mg / min.

What are the base pairs for RNA?

shusha [124]

Answer:

${\boxed {\sf Adenine \ with \ Uracil}}$

$\boxed {\sf Cytosine \ with \ Guanine }}$

Explanation:

In RNA (ribonucleic acids), the nitrogen bases are:

Adenine
Guanine
Cytosine
<em>Uracil</em> (there is thymine in DNA, but not in RNA)

The bases pair like:

Adenine (A) with Uracil (U)

Cytosine (C) with Guanine (G)

So, the base pairs for RNA are <u>A with U </u>and <u>C with G</u>
