Wolves have genes that give them a very powerful sense of smell much more powerful than humans, this is an adaptation by natural selection. The wolves that reproduced more offspring with a better sense of smell thereby increasing the frequency of those genes in the population that survived longer. Give an example of adaptations in other organisms that may have resulted from variations that were favored by natural selection.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.

the answer would be   10%
