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.
Answer:
2.256
Explanation:
This is a percent change problem. The CO2 emitted by a car using gas is 4.7 MMt per year. The CO2 emitted by a car using corn ethanol made from biomass is 52% less than 4.7 MMt.
Find 52% of 4.7 MMt:
0.52 × 4.7 = 2.444.
Subtract 2.444 MMt from 4.7 MMt:
4.7 − 2.444 = 2.256.
The solution is 2.256 MMt.
A spontaneous reaction is one that occurs without outside influence.
The presence of the receptor in a cell for a particular hormone decide whether the cell is able to respond to a hormone. Cells which do not have a receptor are not directly influenced by hormone.
