Olenka [21]

This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution  would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.

Explanation:

The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.

A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.

A solution having lower concentration of solute than the cell cytoplasm is called the  hypotonic solution.

The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.

A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.

A cell placed in hypotonic solution  will undergo endosmosis of water  so it will gain water and its mass will increase.

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/
