Answer: Normally, the invasive species can reproduce rapidly because their environment has no/lacks predators and pests.
They are haploid because they result from meiosis
Has a cell wall but lacks a well-defined nucleus and organelles, and its cytoplasm doesn't have much structure.
<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.
