<u><em>NAD+ and H+ are not the same. </em></u>
NAD+ is an electron carrier. Reactions in metabolism oxidize food molecules and transfer those electrons (along with H+) to > NAD+ which is what forms NADH. Now, NADH is the reduced form of NAD+ and NAD+ is the oxidized form of NADH.
H+ on the other hand, is a proton. It is a hydrogen atom that lost it's electrons. So when you see NADH + H+, that means that the reaction removed 2 electrons and 2 H+ from the compound.
Answer:

Answer:
Polar Bears
Polar bears have white fur which helps aid in camouflaging against the snow. They also have small rounded ears that act as a shield letting no water in to freeze ear drums and reduce heat loss.
Black Bears
Black bears absorb heat through their black skin. Their thick fur and fat act as an insulation and their large bodies reduce heat loss.
They both use their large claws and teeth to catch prey and provide for themselves
Explanation:
If you need any other examples of adaptions of bears let me know because there are a lot I just added the main ones!
<span>A codon is a tree letter nucleotide sequence that represents
amino acids. A single amino acid can have more than one codon. The valine codon
can be one of the following: GTT, GTC, GTA, GTG. This is particularly useful
during the translation of mRNA into protein. </span>
