The term "biodiesel" sounds organic. but actually, to make biodiesel requires a very costly and complicated conversion process. other than money, what other costs limit the use of biodiesel today? a) biodiesel is not readily available today. b) biodiesel can be made from free vegetable oil. c) the plants needed to create biodiesel take up valuable land that could be used for other purposes. d) the carbon dioxide created burning biodiesel is cancelled out by the carbon dioxide used growing the plants.

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).

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
