Which task would be completed by an ecologist?
question 1 options:

explore the medicinal uses of nectar

inoculate cattle against infection

survey and classify mollusk fossils

test the effect of cyanide on algae

Innoculate cattle against infection.

Explanation:

Biologists work on both biotic and abiotic factors, such as cows and viruses that make the infection. A isn't right because it focuses on a material and not a biotic factor like the bees. C isn't right because that is what a paleontologist does, study fossils and other items that are of ancient age. D isn't right because that is what a toxicologist does, they test the harmfulness of certain materials on test objects.

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.
