Nancy and Paul are designing an experiment to measure the amount of honey produced by each of the bee hives they keep. What should Paul and Nancy do to ensure a fair comparison between all the hives? Create a scale that can measure the density of the harvested honey.
Take pictures of the combs before and after they are removed from the hive.
Document the number of honey-making bees per hive.
Establish a standard unit and method for measuring the honey.

I am choosing between C and D.
Can I please have an explanation too if possible.

gold i'm pretty sure i might be wrong

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.

idk
