Isotonic, Hypotonic, and Hypertonic Solutions. Water moves readily across cell membranes through special protein-lined channels, and if the total concentration of all dissolved solutes is not equal on both sides, there will be net movement of water molecules into or out of the cell.
Answer:
because it comes from the everyday activities of many different people, such as fertilizing a lawn, using a pesticide, or constructing a road or building.
Explanation:
Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
Binocular vision. Binocular vision is vision with two eyes, and the main cue for depth perception associated with binocular vision is retinal disparity. ... The disparity (difference) between these two retinal images (retinal disparity) can be used as a cue for depth/distance.
