Alleles of the gene that determines seed coat patterns in lentils can be organized in dominance series: marbled > spotted = dotted (codominant alleles) > clear a lentil plant homozygous for the marbled seed coat pattern allele was crossed to one homozygous farther spotted *tern allele. in another cross, homozygous dotted lentil plant was crossed to one homozygous for clear. an fl plant from the first cross was then mated to an fl plant from the second cross. a. what phenotypes in whet proportions are expected from this mating between the two f1types? b. what ere the expected phenotypes of the fl plants from the two original parental crosses?

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above

bru what tyep of qus is dis

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.
