Answer:
An action potential has several phases; hypopolarization, depolarization, overshoot, repolarization and hyperpolarization. ... The overshoot value of the cell potential opens voltage-gated potassium channels, which causes a large potassium efflux, decreasing the cell's electropositivity.

The correct answer is 2.
The scientific knowledge is constantly growing. The main advantage of the scientific method is that nothing is absolutely true and unquestionable.
With each new hypothesis and experiment, scientists get a little bit closer to the truth about the natural world. Some parts of the scientific knowledge stand through time and new experiments only confirm them. But often, the new research finds new aspects or disproves parts of the previous finds, so the understanding of that phenomenon changes.
One thing that separates us from the other animal classifications is that we have hair, everywhere! :D The next major difference is the fact that mammals don't lay egg's, we give birth to live creatures. Those are the 2 biggest things that distinguish us from them.

Answer: Mitochondria
Explanation: Mitochondria is an organelle responsible for cellular respiration which is the break down of Simple sugars into carbon dioxide,water,ATP( adenosine trisphosphate).
It has a double membrane,known as the power House of the cells found in the cytoplasm of most Eukaryotic organisms.The number of Mitochondria found in an organism varies according to the Oxygen requirements of that organism. In human liver contains about 2000 Mitochondria,the Red blood cells do not contain Mitochondria.
At 5.0 they start to die off so that means 5.5 is where they are dead
