Which observation BEST demonstrates Newton's first Law of Motion? A. A small rock thrown at a trashcan cannot knock it over, but a more massive rock thrown with the same
force at the same trashcan can knock it over.

B. A football thrown by an NFL quarterback has greater acceleration than a football you throw.

C. A book placed beside you in the back seat of a car slides to the floor as the car stops suddenly.

D. An astronaut weighs more on Earth than he does on the moon, but is mass does not change.

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

acceleration = 18/3 = 6 m/s per second.

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.
