That question got me thrown off

Dominant

Explanation:

If both of the parents don't express the trait and the child does, then the pedigree is recessive.  According to Mendel's law, the recessive trait will only show if there are two recessive alleles.  If both of the parents of have the trait and their child does, that means that the parents are heterozygous.

If one of the parents have the trait and the child does or doesn't, then the pedigree is dominant.

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.

more words for this could be abiotic and biotic

abiotic: living organisms within an ecosystem

biotic: non-living organisms within an ecosystem
