Answer:
Humans have some stem cells, but those cells are not easily available to help with healing. Most other mammals are the same, so they aren't good at regeneration either. Amphibians and some fish have stem cells that are more easily available, and are usually pretty good at regeneration.
Answer:
Nitrogen and phosphorus pollution which causes the increase in population of phytoplanktons lead to the process called euthrophication.
Explanation:
Eutrophication occurs when there is excessive level of phosphorus and nitrogen in the water that leads to the increase in population of phytoplanktons or algal blooms. Algal blooms has a negative effect to the quality of water for it creates an environment suited for the growth of bacteria and thereby decreasing the supply of oxygen in water. This leads to death of fishes and aquatic life.
