Answer:
Hypotonic solutions are those with less solute (again read as higher water potential). Isotonic solutions have equal (iso-) concentrations of substances. Water potentials are thus equal, although there will still be equal amounts of water movement in and out of the cell, the net flow is zero.

Viruses are not made of cells, I believe.
I believe the answer is wave summation. They result when one wave of contraction is added to another. A 2nd contraction of the muscle occurs before relaxation of the first contraction is complete. When the stimuli is not strong to enable muscle contraction, it continues to add stimuli until the muscle contracts.
B. Hydrogen bonds make the positive sides of water molecules stick to each other
THE ELECTRON TRANSPORT CHAIN is responsible for releasing energy that is used to pump hydrogen ion. The energy which is released in form of electrons are passed through the electron transport chain and used to pump protons into the thylakoid compartment of the plant cell.
