In general, what is the relationship between degree of ecosystem fragmentation and the rate of edge effects?
select one:
the edge effects in an ecosystem are unaffected by fragmentation.
more ecosystem fragmentation leads to fewer edge effects.
the increase in edge effects results in a decrease in fragmentation over time. more ecosystem fragmentation leads to greater edge effects.

hi there!

explanation: nucleolus is a structure in the nucleus are ribosomes are made.

hope this you!

have a nice day! : )

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.

linnaeus is the father of taxonomy, which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
