The activity of an enzyme is affected by many factors, and each enzyme has an optimum temperature and pH at which its reaction rate is fastest, so when the pH drops to 2, the substrate (A) will no longer fit into the active site (C) because the enzyme has changed shape, as shown in option C.
The enzyme activities are influenced by changes in temperature and pH, so when there is any increase or decrease in these two factors, the shape of the enzyme will get affected, and hence the function gets affected too.
Hence, the activity of an enzyme is affected by many factors, and each enzyme has an optimum temperature and pH at which its reaction rate is fastest, so when the pH drops to 2, the substrate (A) will no longer fit into the active site (C) because the enzyme has changed shape, as shown in option C.

Answer:
C)
The substrate (A) will no longer fit into the active site (C) because the enzyme has changed shape.
Explanation:
b. more carbon in tress in temperate forests
c. rates of photosysnthesis are higher in temperate forests
Answer:
Option A, there is more carbon in the ground in temparate forests
Explanation:
In temperate forests the nutrients are mostly found in the soil including the carbon, while in case of tropical forests these nutrients (including carbon) are up taken by the trees and stored there itself. Now when the tropical forest trees are cut down the carbon reserves with in the trees is destroyed and released in the atmosphere. As per estimate the amount of carbon released by deforestation of tropical forest is much more disastrous than the gas emission of automobiles and industries in the current time.
Hence, option A is the correct choice of answer
Explanation:
When a farmer measures the depth of the soil to measure the saturation point of water in the soil and found that after 1.2 inches the soil is wet but after a week the saturated soil is found at 1.6 inches. There could be many reasons for this:
1. The crops could have utilized the water present in the topsoil.
2. The water has been evaporated from the soil due to farming practices if performed in that week.
3. The water could have percolated down as the soil could be highly porous.
4. The saturation of water depends on the physicochemical factors of soil also.
B. the secretion of acids and ammonia
C. reabsorption of organic molecules, vitamins, and water
D. regulating the rate of filtrate formation and controlling systemic blood pressure
The juxtaglomerular apparatus is responsible for D. regulating the rate of filtrate formation and controlling systemic blood pressure.
JGA regulates renal hemodynamics through the tubular glomerular feedback (TGF) mechanism. This causes macula densa cells to detect changes in tubular fluid flow and composition and induce changes in the diameter and renin secretion of afferent arterioles.
Renin is produced by juxtaglomerular cells, also known as granule cells. These cells resemble epithelium and are located in the media of afferent arterioles as they enter the glomerulus. Juxtaglomerular cells secrete renin in response to the Stimulation of beta-1 adrenergic receptors.

Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.
