An endotherm, also called as a warm-blooded organism, has the ability to generate heat internally. One advantage to being an endotherm, instead of an ectotherm, is that an endotherm can generate its own body heat. This kind of organism can create a favorable level of body heat that is independent of its environment. Endotherms include mammals and birds.
If you use more than one independent variable at a time, and will observe a change, you will not know which variable contributed to a changed result.
Fermentation
The electron transport chain gives off 32 ATP the kreb cycle gives off 2 and so does glycolysis. Fermentation happens in muscles or alcohol
Reaction. I hope this helped have a great day.
