Which of the following types of carbon fixation is associated with plant stomata being open during the night? a. c3 b. c4 c. cam d. all of the above

CAM

Explanation:

Plants like cactus and pineapples uses Crassulacean Acid Metabolism (CAM) pathway to minimize photorespiration. These CAM plants at night open their stomata to diffuse CO2 into their leaves. CO2 is then fixed into oxaloacetate by PEP carboxylase which is a common step in C4 plants, oxaloacetate is then covert  into malate or any other organic compound.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
