Explanation:
The length of the sperm in a few species is much larger or giant than the size of the animal-like observed in the <em>Drosophila bifurca.
</em>
In this fruit-fly, the tails of the sperm are too long which could be accounted for many reasons:
1. The sexual selection prefers the long tails over the small tail.
2. The large sperms can displace the small sperms in the female reproductive organ.
3. The female reproductive organ increases the promiscuity of the large sperms that is favour the large sperms over the small sperms.
I'm pretty sure that it's C. I'm not quite sure though.
Capsule is a structure present in prokaryotes but absent in eukaryotes.
<h3>What are prokaryotes? </h3>
Prokaryotes cells are cells that do not have structures bounded in a membrane. example include bacteria.
<h3>What are Eukaryotes?</h3>
Eukaryotes cells are organisms that have their nucleus and other organelles bounded in an enclosed membrane.
Prokayote e.g Some bacteria have capsules it is carbohydrates in nature and it enables the bacteria to attach themselves to the surface. This is not present in eukaryote cells.
Conclusively, Capsule is the structure present in prokaryotes but absent in eukaryotes.

First answer is correct. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.
