jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including earth. on earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). hope this < 3
if a grape was put in hypertonic solution, water will move down the concentration gradient from high concentration (in the grape) to low concentration (the solution), causing it to shrink.
water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
hope this < 3
