Atlantic cod is a benthopelagic fish that is consumed primarily by humans. These are commercially known as codling. From the given choices, legal regulations and increasing reproductive capacity are both beneficial to the population of the cod. The water temperature is also likely to affect the population but not as much as overfishing does. Therefore, the answer is the first choice.
In C4 plants, photosynthesis is compartmentalized into two; light-dependent stage and light independent stage. The light-dependent stage occurs in the mesophyll cells of the leaf. Here, CO2 is fixed into oxaloacetate by PEP carboxylase enzyme. The oxaloacetate is then converted to malate that is then transported to bundle-sheath cells (around the leaf veins). The CO2 is then released from the malate and the gas molecule is subsequently fixed by RuBiSCO like in C3 plants. The biggest advantage of C4 photosytheis is that the wasteful process of photorespiration is greatly reduced.
