Cats normally have a total of 18 toes, 5 on each front paw and 4 on each back paw. but some cats express the dominant phenotype for polydactyly, which results in the development of extra toes on one or more paws. jake, a canadian tabby cat, has 28 toes and is recognized by the guinness book of world records as the cat with the most toes. suppose that jake mates with a female cat, lucy, who has 18 total toes. over several years, they have multiple litters and a total of 16 kittens (10 males and 6 females). the total number of toes on each kitten ranges from 21 to 25.if we use the letter p to represent the polydactyly gene, what is jake's genotype? a. ppb. ppc. ppd. you cannot determine jake's genotype from this information

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.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
