Answer:
ribose and/OR deoxyribose
Explanation:
im not sure though, it might be wrong.
The basic components (depedent and indepedent variables) are the plants and altitude while the confounding variable is the 20 story building. Confounding variables affect the experiement variable and are mainly outside of the researcher’s control in the experiment. Ray cannot change the building but this variable can affect the depedent and indepedent variables and cause distorted or spurious results.
The knowledge gained will lead to further experimentation that could potentially result in a new use for the drug.
