Answer:
The impulse will not be transmitted
Explanation:
The nervous system sending a signal by triggering the action potential of the cell. To trigger the action potential, a certain threshold of membrane potential has to be reached. Acethylcholine is a neurotransmitter that can change the membrane potential, and if the number if enough will trigger an action potential.
If the number of acetylcholine is not enough, there will be no action potential triggered and the signal will not be transmitted. Since the signal won't reach the muscle, then muscle contraction will not happen.

As the wolf population increases, the need for food will increase, causing the wolves to hunt more hares, making the hare population decrease.
Answer:
Explanation:
Osmosis is the process in which the molecules of a solvent move from a region of low concentration to a region of higher concentration through a semi-permeable barrier.
While eating the chips, <u>the salt content from the chips makes the surrounding solution of the cells to have an increase in salt concentration causing an hypertonic solution</u>. An hypertonic solution is a solution that has more solute (salt) than the (solute in a) cell. <u>This increase in salt concentration around the cells causes the cells to release water to neutralize the high salt concentration in the solution around the cell (in order to maintain homeostasis)</u> which causes dehydration in the individual and hence making the individual to be thirsty. <u>The body attempts to maintain balance by passing this excess salt out of the body in the form of urine hence the reason for the dark colour in the urine </u>(because if the body doesn't rid itself of the high salt concentration, the cells could shrink and die as a result).
