What statement about enzymes and pH is true? A Most enzymes require a very acidic environment to function well.

B Most enzymes require a very basic environment to function well.

C Enzymes are unaffected by changes in pH levels.

D Enzymes require a specific range of pH values to function.

D. Enzymes require a specific range of pH values to function.

Explanation:

Enzymes function the best in a neutral pH, rather than in very acidic or basic environments.

Enzymes are very affected by changes in pH levels because they perform much better in neutral environments.

telophase and anaphase

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
