Diego is studying compost. He conducted an experiment to see how moisture levels affect the breakdown of organic materials in co
mpost piles. Diego found that adding 1 L of water per 10 kg of dry matter caused the compost to break down at the fastest rate, but adding more than 1 L caused decomposition to slow down. Which of the following questions do these results lead to? I. Why does adding more than 1 L of water per 10 kg cause decomposition to slow down? II. Does this ratio of water to dry matter hold true for all organic materials being composted? III. Why should anybody want to start a compost pile? A. I, II, and III B. I only C. I and II only D. II and III only
The study conducted is done only for people or organisations that either started a compost pile or who want to start a compost pile. Thus result III is not at all a valid question for the study conducted.
However, there can be question related to the result of experiments clarifying the quantity of additives used in the experiment for example why only 10 Kg of dry water, why not to add more than 1 L of water , why only water is to be added why not some other solvent etc. Thus question I is a valid question.
Also , question II is valid as it asks about expanding the scope of experiment from one type of organic material to all other type of organic matter in the compost.
There fore both question I and II are valid question and thus option C , is correct.
Similarly to their eukaryotic counterparts, bacterial chromosomes perform the complex task of efficiently compacting DNA while supporting gene regulation and proper DNA segregation. Chromosomes are thus shaped at multiple scales by a large number of proteins and DNA enzymes
