Directional selection is a type of natural selection that favors one extreme phenotype over the mean or another extreme. Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution.
Stabilizing selection, also known as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of stabilizing selection is birth weigh in humans.
Disruptive selection is a type of natural selection that shows a preference toward the reproduction of genetic material at the extremes within a population.One of the most studied examples of disruptive selection is the case of London's peppered moths.

Answer: salt
Freshwater is defined as having a low salt concentration, usually less than 1%.
Explanation:
Freshwater refers to the bodies of water that contain very low levels of dissolved salts. So, freshwater are unique for their low salt content (about 0.5% of salt) compared to the sea water with high salt content.
Examples of freshwater include rivers and spring
A) Net movement in osmosis is from areas of higher water concentration to areas of lower water concentration. Net movement in diffusion occurs from areas of higher solute concentration to areas of lower solute concentration.
This happens so that both solution have roughly the same concentration
<span>The Food Safety Manuel dictates that you scrub your hands for about thirty seconds. Scrubbing refers to rubbing soap over your hands, not the entirety of handwashing. One must then place their hands under running water for a suggested twenty seconds. Dry your hands using a blow dryer or a paper towel. Do not touch the sink handle after scrubbing your hands!</span>
