Which nutrient can be used to produce energy in the absence of oxygen?
serg [7]
Answer;
Glucose
The nutrient that can be used to produce energy in the absence of oxygen is glucose.

Explanation;
Production of energy without using glucose is called anaerobic respiration. During this type of respiration less energy is released than the case of aerobic respiration. This is because the breakdown of glucose is incomplete. Anaerobic respiration produces an oxygen debt, which is the amount of oxygen needed to break lactic acid to carbon dioxide and water.

A potential cause of male infertility is a blockage of the vas deferens. The blockage could be due to the build up of scar tissu
Ilya [14]

Answer:

The type of treatment indicated to treat infertility due to blockage of the vas deferens is surgery to remove the obstruction (option C).

Explanation:

Blockage of the vas deferens is a known cause of obstructive azoospermia, which prevents the passage of sperm and causes infertility. This type of obstruction can be corrected by surgery, part of the treatment of infertility from this cause.

The vas deferens are in charge of conducting the sperm from the testicles to the ejaculatory ducts, which prevents these gametes from being expelled to fulfill their function in reproduction.

The other options are not correct because:

<em>     A. </em><u><em>Medication to stimulate sperm production</em></u><em> does not resolve the blockage. </em>

<em>     B. </em><u><em>Hormone therapy to increase testosterone </em></u><em>could be considered for infertility treatment, but the obstructive problem continues. </em>

<em>     D. </em><u><em>Semen implantation in the testes</em></u><em> does not exist as a medical treatment.</em>
