What happens to the lactase enzyme in someone suffering from lactose intolerance? A. The substrate lactose acts as an inhibitor to the lactase enzym
B. The body produces too much lactase enzyme
C. The lactase enzyme is shaped the wrong way and can't lock into place
D. The body produces too little lactase enzyme

choice D

Explanation:

The body produces too little lactase enzyme​.

Lactose intolerance occurs when your small intestine doesn't produce enough of lactase to digest milk sugar (lactose).

Lactose intolerance in adulthood is caused by gradually decreasing expression of the LCT gene after infancy, which occurs in most humans. LCT gene expression is controlled by a DNA sequence called a regulatory element, which is located within a nearby gene called MCM6.

Some individuals have inherited changes in this element that lead to sustained lactase production in the small intestine and the ability to digest lactose throughout life.

People without these changes have a reduced ability to digest lactose as they get older, resulting in the signs and symptoms of lactose intolerance.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
