ohm’s law
V=IR
difference between mitosis and meiosis
mitosis = results in two diploid cells. meiosis= 4 haploid cells
nitrogen fixation
making nitrogen in atmosphere usable. required to biosynthesize basic building blocks of plants, animals, and other life forms. animals and plants need nitrogen to build amino acids
