What is the result of eutrophication?

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.

Explanation:

Recombinant DNA technology is a major DNA-based tool that opens a new age for modern biotechnology. With this technology, a gene or multiple genes can be identified, cut, and inserted into the genome of another organism. Using this technology, the first drugs of medical biotechnology were produced, namely human insulin.
