How often does the body perform cellular respiration?
a. once in the morning and once at night
b. only at night
c. continuously
d. only when the body runs out of atp

Ans. (C).continuously.

Cellular respiration can be defined as a metabolic process, which involves breakdown of carbohydrate molecules to produce energy in the form of ATP molecules. These ATP molecules release energy during chemical hydrolysis.

Cells present in body require a continuous supply of energy to preform all of metabolic reactions. Hence, cells perform cellular respiration continuously or constantly.

Thus, the correct answer is option (C).

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
