Explanation:
Sorry if I'm wrong have a good one!
The 2 substances needed are ADP and NADP.
Okay, so overall, the unicellular (presumably bacterial) organisms are going to be the most similar when talking about genetic material as the genetic material doesn't have to code for as many proteins as it would in a multicellular organism. For example, in humans, our genome codes for every protein in every cell in every tissue in every organ in every system in your body. However, unicellular organisms have to code far less as they have a very limited amount of proteins that they actually have to form. You'll have some differentiation when it comes to diet, but overall, the answer should be organisms A and C.
Hydrogen atoms in compounds such as h2 and H2o are joined to the molecules with covalent bonds. This is where electrons are shared between the atoms in order to fill there valence shells.
As we mentioned before, hydrogen can only form one covalent bond because its 1s electron orbital holds a maximum of two electrons. Hydrogen can form either a polar covalent bond or a non polar covalent ( cause there is no electronegativity difference between the two molecules).
Water contain polar covalent bonds because the oxygen has a grater electronegativity than the hydrogen atom.
