Energy is stored in the covalent bonds between phosphates
The three stages of Action Potential are:
1. depolarization- Na+ channels open up inside of the membrane and becomes more positive than the RMP.
2. repolarization- The Na+ channels inactivating and K+ channels opening AP spike stops rising to which the membrane returns to RMP.
3. hyperpolarization- A few of the <span>K+ channels remain open and the Na+ channels reset inside of membrane becomes more negative than RMP.
Hope this helps!

Answer:
Rapidly and Accurately
Explanation:
As an example, eukaryotic human DNA replicates at a rate of 50 nucleotides per second.
Replication occurs so quickly because multiple polymerases<em>, or think: enzyme+polymer=polymerase,</em> can synthesize<em>, or combine or fuse,</em> two new strands at the same time by using each untwined strand from the original DNA double helix as a guide.
DNA replication is so much faster than bacteria replication because it's extremely difficult to replicate DNA accurately, as well as copying molecules that tightly complexed with histones in nucleosomes, which work together to form chromatin, which is the material that chromosomes are composed of, and it's further composed of protein (histones), DNA, and RNA.
Therefore, the reason for human cells taking significantly less time to replicate its genome is <u>accuracy</u>.
The cell membrane is made up of a phospholipid bilayer: a phosphate group attached to two fatty acids.
Answer:
A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it. The most likely materials are crystalline silicon, amorphous silicon, gallium arsenide and organometallics (soluble platinum).
