How does growing beans in a ziplock bag is faster than in a cup with soil ?

We kept our growing beans in a bag for about two weeks. By then a few of the bean plants grew so tall they started pushing up against the plastic baggie! After two weeks we pulled the paper towel out of the baggie to get a better look at the root systems and the growing stems.

Explanation:

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.

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.
