Answer: The bond of molecule AB is then best described as a covalent bond
Explanation: The bond molecule AB is covalent because the difference in their electronegativity is not very big
Answer: It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation). All four stages of photosynthesis are tightly coupled and controlled so as to produce the amount of carbohydrate required by the plant. All the reactions in stages 1 – 3 are catalyzed by proteins in the thylakoid membrane. The enzymes that incorporate CO2 into chemical intermediates and then convert it to starch are soluble constituents of the chloroplast stroma (see Figure 16-34). The enzymes that form sucrose from three-carbon intermediates are in the cytosol.
The answer to your question would be C. Also you put two "B"'s XD
Pinky , ur anwser is Nitrogen. Which is present in the atmosphere by 78%.
Thankyou.
