To identify the molecule that accepts CO2, Calvin and Bensons manipulated the carbon-fixation cycle by either cutting of CO2 or cutting off light from cultures of photosynthetic algae. They then measured the concentrations of various metabolites immediately following the manipulation. How would these experiments help identify the CO2 acceptor?A) CO2 acceptor concentration would decrease when either the CO2 or light are cut off. B) CO2 acceptor concentration would increase when either the CO2 or light are cut off. C) CO2 acceptor concentration would decrease when the CO2 is cut off, but increase when the light is cut off. D) CO2 acceptor concentration would increase when the CO2 is cut off, but decrease when the light is cut off.

CO2 acceptor will decrease when CO2 is cut off but will increase when the light is cut off.

Explanation:

This is so because algelae will grow well in presence of CO2 and darkness

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
