In an experiment, a scientist notices that an enzyme’s catalytic rate decreases when the ph of the environment is changed. which of the following best summarizes the effect of ph on the enzyme? a.) ph changes the shape of the enzyme. b.) ph changes the atomic structure of the enzyme. c.) ph changes the ability of the enzyme to dissolve in water. d.) ph takes energy away from the enzyme, thus slowing it down.

D. Catalysts have extra energy to make certain chemical reactions start if the PH of the environment directly affects the catalytic properties of the environment then it might be using that energy to remain stable.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
