A test for the presence of fructose in the semen is an easy indicator that can give a possible explanation to no sperm seen in the ejaculated fluid. A negative test would likely indicate which of the following rationals?

A)a reason can't be determined by a fructose test

B)there isn't a contribution from the seminal vesicles, so there is a possible obstruction in the upper portion of the reproductive tract

C)there is no contribution from the epididymis so there is a cellular malfunction so no sperm are produced

D)there isn't a contribution from the prostate gland, so there is a possible obstruction in the lower portion of the reproductive tract

B)there isn't a contribution from the seminal vesicles, so there is a possible obstruction in the upper portion of the reproductive tract

Explanation:

Seminal vesicles produce thick fluid that contains Fructose and other nutrients. The fluid from seminal vesicles constitute about 50-60% of total semen ejaculated. Since seminal vesicles are present in upper portion of the reproductive tract and there is no fructose detected so it is a possibility that there maybe the obstruction in the upper portion of the reproductive tract.

answer; i believe the correct answer is (sporophyte);

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
