Consider the genetic cross between two purple-flowered pea plants. in this example, heterozygous purple flowered parents could potentially produce offspring with white flowers. we say that the probability of producing white flowers, in this case, is 25%. what statement regarding this cross is not accurate?

a. it is possible to have offspring with only purple flowers and no white flowers.
b. in the population of offspring from this cross, there will be genetic variation.
c. random assortment of chromosomes produced gametes for either purple or white flowers.
d. among the offspring of this cross, the ratio of purple to white flowers will always be 3: 1

D.)

Explanation:

Among the offspring of this cross, the ratio of purple to white flowers will always be 3:1.

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.
