It is an essential element for plant life, but when there is too much of it in water, it can speed up eutrophication (a reduction in dissolved oxygen in water bodies caused by an increase of mineral and organic nutrients) of rivers and lakes. Soil erosion is a major contributor of phosphorus to streams.
Answer:
d. carbohydrates
Explanation:
The products of this equation actually belong to carbohydrates.
Carbohydrates are known to be a large group of organic compounds which is seen in foods and living tissues. Carbohydrates usually contain hydrogen and carbon and are in the ratio 2:1. When broken down, it releases energy which animals use for work.
Two known common carbohydrates are the starch and cellulose. They are macromolecules and are also polymers. Their monomers are units of sugar (glucose). Carbohydrates have the general molecular formula C<em>m</em>(H2O)<em>n </em>(where <em>m</em> and <em>n </em>represent numbers).
Answer: The nervous system of human body is responsible for thermoregulation.
Explanation:
Thermoregulation is the process whereby an organism maintain its internal temperature despite changes in External temperature. The nervous system of human body is responsible for thermo regulation. The nervous system consist of nerves cells and fibres which send nerves impulses to the body parts. It comprises of central nervous system and peripheral nervous system. The centsl nervous system consist of brain and spinal cord while the peripheral nervous system consist of nerves. A part of the brain (central nervous system)called hypothalamus controls thermo regulation. When it senses a change in internal temperature of the body, its send signals to the organs, muscles, glands and nervous system , they respond differently so as to restore the body temperature to its normal one.
