There are choices for this question namely:
<span>movement of oocytes </span>
<span>movement of sperm if present </span>
<span>expelling of the fetus at delivery </span>
<span>all of the above
</span>
The correct answer is "all of the above". The smooth muscle layers in the female reproductive tract facilitates the movement of oocytes from the ampulla of the fallopian tube to the uterus. If sperm is present, the contraction of smooth muscle in the uterus will propel the sperm towards the fallopian tubes where it can fertilize the ovum. At delivery, uterine contractions (along with an adequate pelvis) facilitate the delivery of the fetus; without which the labor will be dysfunctional or prolonged and this is called dystocia.
All living cells need nitrogen to make nuclei acids, proteins, and other cellular constituents. Plants absorb nitrogen and put them into amino acids and proteins.
<span>In the light reaction, when electrons are transferred from photosystem 1 to photosystem 2, it goes through an electron transport chain. This ETC pumps protons into the thykaloid. Those protons diffuse out of the thykaloid through ATP synthase which energizes a phosphate group to bond to ADP. This creates ATP.</span>
Gamete production is a function of meiosis rather than a function of mitosis.
