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.
I am guessing that the molecule type will try to take over the cell OR it will excrete to much waste for the cell to handle and the cell will die.
I am just guessing, but I hope this helps
Ok... This is a bit complicated but bear with me. In a female's body Estrogen and Progesterone are two of the major used to maintain the menstruation cycle. Gonadotrophic substances are an entirely different topic with it being the hormones FSH and LH (These hormones are released while an egg is in development in the ovaries).
Without going into even deeper specifics. Estrogen is used by the body signal to ovulate, as well as thicken the uterine walls... Progesterone is used to maintain the uterine walls "after" the egg is fertilized. What the pill is suppose to do is actually force a premature ovulation, which is why there is estrogen. The Progesterone's job as is maintain the uterine wall's endometrium to a low level and helps keep blood loss from a period at a minimum.
If you need clarification please feel free to question.
