Study the energy curve for the reaction A + B --> C + D. Which letter a. - e. represents the amount of activation energy needed for the enzyme catalyzed reaction?

answer; i believe that the correct answer is ; males are hemizygous for the x chromosome;

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

the correct answer was location c, because earth is tilted away from the sun at this time
