Helo! i was wondering if anyone could help me of these two questions for biology?

1) A 2) B

Explanation:

Enzymes are catalyst, meaning that they could be use in several reaction and they speed up any chemical reaction rate. So knowing this, when the animal have more enzymes it will react more quickly with the food, making it digest the food more quickly.

Hope the help, cheers

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
