The answer is no cell wall. plant cells have cell walls and if animal cells had cell walls, we wouldn't be able to move as freely as we do.
Removing the layers that surround the oocyte is due to the action of 100 sperm, but one sperm will fertilize the oocyte.
<h3>How does the sperm fertilize the oocyte?</h3>
When sperm and an oocyte (egg) join, their nuclei fuse, resulting in fertilization. These reproductive cells combine to produce a diploid cell (zygote) since each is a haploid holding half of the genetic material required to become a human being.
The surviving capacitated sperm come into contact with the oocyte as it travels along the distal uterine tube and move toward it in response to chemical attractants secreted by the corona radiata cells. The sperm must get beyond the two protective layers to reach the oocyte itself.
The sperm first penetrates the corona radiata cells. The sperm then bind to receptors in the zona pellucida when they come into touch with it. This starts a process known as the acrosomal reaction, in which the sperm's acrosome, an enzyme-filled "cap," releases its reserve of digesting enzymes. These enzymes make it possible for sperm to get through the zona pellucida and reach the oocyte. Finally, a single sperm contacts sperm-binding receptors on the plasma membrane of the oocyte. The head and mid-piece of the "winning" sperm then enter the interior of the oocyte after the plasma membrane of that sperm fuses with the oocyte's plasma membrane.

Answer:
Flaccid paralysis.
Explanation:
Demyelinating disease may be defined as in which the protective layer of myelin sheath gets damaged. This causes the slow down or even stops the transfer of nerve impulse.
Flaccid paralysis is the neurologic condition that results in the reduced muscle tone due to damage in the nerves of the muscles. The contraction is inhibited in the flaccid paralysis. The demylination results in no contraction at all as occur in flaccid paralysis.
Thus, the answer is flaccid paralysis.
Answer:
The answer to the question is amplitude
Explanation:
This is the answer to the question because a month ago I took the quiz and I got the question. Amplitude doesn't relate.
Much more carbon will be present in the landscape, seeing as plants which absorb it have been removed in quite large quantities. A major avenue of carbon absorption has thus been removed. In addition, immense amounts of carbon will have been released into the air from the burning itself. This carbon, combined with the otherwise existing carbon that is now stuck in the atmosphere (with no trees to absorb it), will contribute to pollution.
