Being a plant biologist, I might have a different interpretation - there are whole sequences of the life cycle that are haploid. Maybe make the stem more specific?

# data[].attributes.body
This revision moves up the blooms level because they must really understand multiple aspects of the process. It also uses a lot of vocab. I agree with Carolyn though, be more specific about exactly what type of cell you are looking at!

I like the revision; the question set is a nice way to get at important concepts that we know are issues for students.

# data[].attributes.body
I like the T/F! I think it's a great way to pack lots of aspects of one topic into one question. These are still a lower level blooms question. Consider talking about where you might find it or what it might react to.

Honestly, I like both versions of the question. For me, the cognitive load of the original isn't bad, as it is essentially 4 consecutive T/F questions. (Molecule either is or is not a nucleotide.) However, I agree with others that the revised version lets you probe more than just structure recognition.

Nice rewrite! I am wondering if it is possible to get an application level T/F in this question, these seem to be mostly comprehension options (but maybe that's all is needed here).

# data[].attributes.headline
I can see the benefit of the revised version checking students' understanding of each option, rather than just finding the one that must be true and stopping there. So if that was the goal, good job! I might consider replacing some of the ATP's with "ATP production" or "ATP hydrolysis" as appropriate. For example, for the first T/F, ATP just sitting there in the cell doesn't dissipate free energy, but I think you're asking about the process of ATP production or ATP hydrolysis.

The wording in the stem implies that there are only 2 things to rank.  Should it be rank from 1 to 4?
This could be a multiple choice question if you gave them possible rankings and had them chose the correct one.
