<u>Answer</u>: c natural selection - smaller guppies became less visible to predators d selective breeding - predators select prey based on preferred traits.
In nature, predators prefer larger individuals. They will provide sufficient nourishment, not only to compensate for the used energy during the hunt, but also to sustain the individual for a period of time. Smaller individuals are hunted only if they are infants and thus vulnerable and easily caught.
Thorugh the introduction of the predator, being small became evolutionary advantageous. Thus, large guppy where preyed upon and did not succeed in reproducing. However, small guppy survived and reproduced successfully, thus passing on their genes. The next generation will be composed by the offspring of the smaller fish.
<span>Melanin helps protect the skin against effects of the sun such as skin cancers and premature aging. In African American skin, melanin provides a sun protection factor (SPF) equivalent to 13.4 compared to 3.4 in white skin and thus the former have lower incidences of skin disorders associated with exposure to the sun.</span>
Answer is hypertonic.
The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is concern for all living things, especially in in organisms lacking cell wall, <em>Paramecium</em> is one such protozoan. It has specialized structures called contractile vacuoles. A contractile vacuole collects excess water from the cell and release it out, keeping the cell from lysing as it takes on water from extracellular environment which hypotonic (a lower osmolarity than the cell’s cytoplasm) as compared to hypertonic environment inside <em>Paramecium</em>.
