Explain what friction, corollas, and a low pressure gradient does to an air parcel. Please give the shortest answer you can give. I’ll give brainliest.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
