The cell cycle produces daughter cells that select one:

a. are genetically identical to the parent cell (assuming no mutation has occurred).

b. have the same number of chromosomes as the parent cell but not the same genetic content.

c. have a random assortment of maternal and paternal chromosomes.

d. have the same number of chromatids as the parent cell had chromosomes.

e. none of the above.

burning fossil fouls really decrease the carbon in the atmosphere so b

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.
