How has technology been used to address issues to sewage

Biology
1 answer:
vfiekz [6]3 years ago
7 0
The answer is A, as most sewage treatment plants use bacteria to break down and remove nutrients. The main water pollution problem caused by sewage effluent is eutrophication, related to the release of nutrients into rivers and lakes. Nutrients such as nitrogen and phosphorus ions result in high algal growth. Some algal blooms release toxins, and algal blooms also disrupt the natural dissolved oxygen concentration cycles. Fish kills are often because eutrophication has resulted in anoxic conditions. 

Anyway, wastewater treatment plants utilise bacteria to facilitate nitrification or denitrification, which removes ammonia and nitrates/nitrites, respectively.

if a human cell with a chromosome number of 46 undergoes meiosis, what number of chromosomes will be in each daughter cell?
KiRa [710]

Explanation:

It's a piece of cake. Here we are provided with the information that a human cell with a chromosome number of 46, undergoes meiosis, what number of chromosomes will be in each daughter cell.

To solve this question first you must be aware about the word meiosis. Meiosis is a type of cell division. It's end product results in the formation of four daughter cells each having half the number of chromosomes as that of the parent cell.

Did you notice? That formed daughter cell will have half the number of chromosomes as that of the parent cell. Hence, 23 chromosomes will be in each daughter cell.
