Answer 1

Answer:

Hey, here's the answer

Explanation:

1) Catalase

2) True

3) The optical power of a lens is equal to the reciprocal of the focal length of the lens. P = 1/f. SI unit of power is dioptre (D) and that of focal length is metre (m). 1 D = 1 m −1

Please mark as brainliest, as this was a tough one.

Really appreciate it!
