In ancient times, scientists believed that matter could be destroyed by burning or breaking. modern scientists believe that matter cannot be destroyed. what best accounts for these different opinions? a. scientists with varied backgrounds make different interpretations b. scientists come up with different hypotheses without enough evidence c. scientists believe in discarding all interpretations which were made in the past d. scientists propose different hypotheses to include all the scientific possibilities

A.scientists with varied backgrounds make different interpretations.

Explanation:

The scientists having knowledge of different aspects of scientific principles and skills can give different opinions to the situations. This is not necessary that the scientists working on modern technology will have the same opinion about the scientific research and innovations as that of the ancient scientists. Hence, they can make different opinions.

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.
