Answer:
Ribonucleotides (RNA) and deoxyribonucleotides (DNA). See more details below, please.
Explanation:
Ribonucleotides are the nucleotides of the RNA (they have pentose, ribose and nitrogenous base, except for Thymine; they contain uracil). Deoxyribonucleotides are the nucleotides of DNA (they have pentose, deoxyribose and nitrogenous base, they have Thymine).
The subatomic particles/units that govern potential chemical reactions among elements are "electrons".

Answer:
B. similar to the cells just treated with the dye - 0% dead
Explanation:
According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.
Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.
A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead
It helps them stay safe from predators
