Overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change soil erosion, poor air quality and undrinkable water.
<u>Answer</u>:
The enzyme activity decreases due to the denaturation of the enzymes.
<u>Explanation</u>:
Enzymes are built with proteins. Enzymes catalyze a reaction by binding to the substrate molecule in its active site. As temperature increases the rate of the enzyme activity increases because kinetic energy of the molecules get increases.
But when the temperature crosses approximately 37-40 degrees Celsius the structure of enzyme denatures due to breakage of its intra- and intermolecular bonds. The active parts of an enzyme changes and it can no longer bind to its substrate hence the enzyme activity decreases.
The role of the liver in waste removal is to filter urea out of the blood and into the bladder. Thus, option A is correct.

Answer:
Option A
Explanation:
As per the principle of intrinsic fitness, a person likes to work for his/her inner satisfaction driven by motivation within him/herself.
Thus, a young bird which feels an urge to produce chicks by mating each year will ultimately go outside to find his/her mate on their own and will produce chick every year. In an intrinsic behaviour the rewards achieved are internally self satisfying and thus a person need no assistance in achieving them on their own.
Thus, option A is correct.
