Which of the following best describes the transfer of phosphates and the impact on the environment and human health?
- phosphates decrease the growth of algae in surface water bodies, and an overpopulation of fish in surface water bodies occurs.
- detergents containing phosphates are carried from land to water by rain, contaminating drinking water and causing digestive problems in humans.
- leaky septic tanks transfer phosphates into the groundwater and are converted into nitrites in the human body, which are poisonous and could be fatal for infants.
- nitrates increase the amount of organic substances in water and lowers the amount of dissolved oxygen, killing fish.

d.

explanation:

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.

explanation:

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
