A mouse is heterozygous at four different gene loci, with a genotype of AaBbCcDd. For each gene locus, the upper case letter represents the dominant allele and the lower case letter represents the recessive allele. These four allele pairs follow Mendel's principle of independent assortment. Knowing this, and assuming normal segregation of alleles during meiosis, complete the sentences with the correct terms.

geologic time scale (for gradpoint) =)

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
