1. how can darwin legitemately argue about the imperfection of the fossil record and then go on to show how the fossil record can be used to support evolution? 2. why are transitional species, such as the ancestors of modern whales or horses, crucial evidence for evolution? 3. even if a "rudimentary organ" actually has a function about which we observers are unaware (e. g., if vestigal pelvic bones of a whale may function to support gonads), why would it still provide excellent evidence in support of evolution by descent? pls ; ; ;

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds

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.
