Answer:
A
Explanation:
There is no much more to say than the letter A describes the process of facilitated diffusion.
The normal diffusion ocurres when the solute passes the membrane through the space of the double layer of phospholipids. Particles that are small and apolar can pass trough the membrane without problems.
For bigger or polar particles we need to use a protein system to help them pass into the cytoplasm. That's what we call Facilitated Difusion.
About the other options:
B) That's the explanation about active transport. That happen for every particle who is going against the gradient of concentration.
C) Again: if we are talking about diffusion, there is no energy needed.
D) The Water Molecules suffer the process os osmotic pressure. Water deslocates to the higher gradient of concentration - contraty what the other particles do.

Answer: doctor may be able to determine the cause by listening to your medical history and doing a physical exam. If necessary, they also can order a blood or urine test to help confirm a diagnosis, or a "culture test" of tissue to identify bacteria or viruses.
Explanation:
Answer: Spermatogenesis begins at birth and continues throughout a man's life.
The process in which
haploid spermatozoa develop from germ cells in the seminiferous tubules of the
testis is known as Spermatogenesis. Thus, the process of spermatogenesis start
with mitotic division of the stem cells that is located close to the basement
membrane of the tubules. However, a mature male gametes known as sperm but it
is commonly known as spermatozoa.
