Answer:

The elements that are sources of water pollution are the following:

1. industrial waste

2. Increase in temperature

3. the use of pesticides in agriculture

4. deforestation

5.possible oil spills

2. Global warming also influences water pollution. If the temperature is increased, water sources decrease the amount of oxygen.

3. The use of fertilizers and chemicals for food production. These products are filtered by underground channels that end up in water networks.

4. Tree felling helps rivers dry out, and exposed roots cause sediments to occur under the ground and contamination of water sources.

5. The spills of crude oil and its derivatives. These spills are due to the poor transport of oil and the filtration of gasoline, which is stored in underground tanks; In some cases, these tanks are leaking and the contents are filtered to nearby bodies of water

The ovulatory phase is characterized by a surge in the luitenizing hormone (which stimulates the release of eggs) and follicle stimulating hormone with a decrease in the level of oestrogen and a gradual increase in the level of progesterone.

The luteal phase is characterized by a general decrease in the levels of luitenizing hormone and follicle stimulating hormone while oestrogen level may remain high.
