What color does purple yellow make? Purple and yellow mixed together can result in magenta or white, depending on the ratios. When you are mixing light, the mechanism is called additive color mixing, and is a bit different from how paint mixing works. Why does mixing red and blue make purple? What colors blend well […]

Which state is not a physical state of matter? There is water vapor above a pot of boiling water. That vapor (or gas) can condense and become a drop of liquid water in the cooler air. If you put that liquid drop in the freezer, it would become a solid piece of ice. No matter […]

How many chromosomes does meiosis start with? 46 chromosomes Are cells haploid after meiosis? By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes.
