Answer:

The answer is Catalase.

Explanation:

Cells have enzymes that help regulate chemical reactions. Enzymes need a substrate to act on. In this reaction, catalase is the enzyme that acts on hydrogen peroxide, the substrate, and breaks it down to water and oxygen. In this way, catalase protects the cells from the potential oxidative damages of hydrogen peroxide.

The correct answer is - They supply the energy needed for living processes.

Both the carbon and the nitrogen, are gases that are crucial for the survival of the organisms on the planet. They are mostly used by the producers in the ecosystems, as they need them to manage to perform their cycles, get nutrition, and of course energy. The producers are the basis of the ecosystems, so if they do not have a healthy supply of carbon and nitrogen, the ecosystems on the whole planet will collapse. The carbon and the nitrogen later go from one organism to another as the energy is transferred, and usually end up back into the atmosphere again.

Answer:

<h3>The Prokaryotic Cell</h3>

Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

Can someone atleast tell me which line is which so I can color code please
Olegator [25]

Answer:

See attached image

Explanation:

Action potential can be split into 5 phases (0-4), where phase 4 leads from one action potential to the next. Phase 0 is the line up and is known as depolarization, it is here where the action potential is triggered and fast Na channels will open. Next, is phase 1 called early repolarization which is the little bit at the beginning of the plateau-here the Na channels will close. Then you have the plateau phase where Ca channels are open at the beginning and close at the end. Then is phase 3 called repolarization which is the big slope down and here is where the normal transmembrane ionic concentration gradients are restored. Finally, phase 4 which is the resting phase occurs. There are many resources online if you need more details, here is a pretty good one: http://www.pathophys.org/physiology-of-cardiac-conduction-and-contractility/
