Answer:
True
Explanation:
Denaturing is a process in which protein looses its shape. Due to loss of shape (structure), protein also looses its function. This change in shape is due to change in temperature or pH of the protein.
Due to high temperature the shape of active site gets distorted due to which it becomes non functional. Change in active site of enzyme will change shape of the enzyme and make it unfit for the substrate/reaction.
Nitrogen makes most of the atmosphere of the earth
They develop into the cell wall and cell membrane
Robin can have a ddt concentration of 444ppm while the ddt concentration of soil is 10 ppm. This happens due to biological magnification.
<u>Explanation:</u>
In biological magnification the concentration of toxic substances at successive trophic levels keeps increasing. Due to biomagnification, what starts out as a small concentration grows while moving to successive trophic levels. DDT is a pesticide which is used to kill pests that affect crops.
DDT used in farms gets deposited in the soil. From the soil it can reach various trophic levels. At each trophic level its concentration keeps increasing.
Robin is a bird that is a secondary consumer and thus belongs to the higher trophic level. Thus even if the DDT concentration is as low as 10ppm in the soil its concentration will keep increasing and can become a high value like 444ppm.
