Small sections of dna that have been sequenced can be assembled back into the original complete sequence by using dna ligase performing a modified pcr reaction looking for overlaps in the code using mitochondrial dna as a guide

is called echinoderms

explanation:

okay now i don't know this but for the pints nothing else to say bye

substitution is the answer in this case

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.
