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.

The important organic molecule present in adipose tissue is lipid.
<h3>What are lipids?</h3>
Lipids are hydrophobic organic molecules that, having this characteristic, make them part of biological membranes. Lipids have various functions such as energy storage, signaling and as a structural component in membranes.
Lipids can be found as an energy reserve within adipose cells. When there is an excess of calories consumed, the body will store them, among other ways, as lipids within the adipose cells so that when there are moments of energy deficit these can be sent to the blood so that the cells use it as metabolic fuel.
Therefore, we can confirm that the important organic molecule present in adipose tissue is lipid.

Answer:
C. causes cell lysis
Explanation:
The slow release of the bacteriophage progeny from a bacterial host cell causes bacterial cell lysis and further kills the host cell which is the bacteria, this results to the liberation of progeny viruses which then infect new bacterial cells.
Only a type of bacteriophage called the filamentous bacteriophage reproduces without killing the bacterial host cell. The filamentous phages infect majorly gram negative bacteria.
