Active transport is a process requiring energy in which a substance crosses the cell membrane.  When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.<span>

Answer:

Hypotonic solution

Explanation:

hypertonic solution is the one you get when the solute concentration of the water is higher than that of the cells.

isotonic solution is the one you get when the solute concentration of the cell and the water are the same.

hypotonic is the one that you get when the solute  concentration of the cell is higher than that of the waters.

Solute concentration being low reminds me of water. Hypo kind of sounds like hippo and hippos love water. You can use this to memorize the difference between hypertonic and hypotonic solutions.

sukhopar [10]

For an organism to be classified in the animal kingdom it is necessary for that organism to be eukaryotic and multicellular. In addition, he must not be able to produce his own food (he must be heterotrophic), and must eat by eating food taken from the environment.

To be classified in the dilo arthropoda, the organism must have an external skeleton, a segmented body and articulated legs.

To be classified in the insect class, the organism must have a separate body in the head, chest and abdomen, have two antennae, two pairs of wings and three pairs of legs.
