Hello, sorry this is a little late.
I believe the correct answer to your question, "an animals long period of inactivity during winter is called what" would be Hibernation.
Hibernation is when some animals (examples would be bears, and wild rabbits) sleep throughout the entire season of winter, when the temperature is too cold for them. They spend time before hibernation usually stocking up food, and creating a warm place for them to stay.
Hope this helps, and have a great day! :)
Answer AND Explanation:
The seminal vesicle produces an alkaline fluid which contains nutrients for the spermatozoa. Near this point is situated the prostate gland whose secretion is alkaline to neutralise the vaginal fluids. It also activates the sperms. The cowper's' gland secretes alkaline fluid that neutralises the acidity along the urethra. All the fluids combine with the spermatozoa from the vasa deferentia to form semen.
Sebaceous glands.
Hope this helps!
