Which of the following describes the epididymis? a. a tube that transports sperm to the urethra b. a vesicle that produces fluid and gives sperm nourishment and motility c. a gland that contributes fluid to semen d. a tube that stores and develops sperm cells from the testes

A tube that stores and develops sperm cells from the testes. Epididymis is a curved structure present on the posterior margin of each testes. Epididymis has three regions head, body, and tail. Near the top of testes is the head of epididymis that stores the sperm until it is matured. Maturation of sperm takes place in the body. The sperms are transported to ejaculatory duct by the tail region.

The correct option is (A)

answer is A..

tube that stores and develops sperm cells from the testes.

Explanation:

so whats the answer

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
