The Law of Reflection states that light will always reflect
A. off a surface at the same angle it strikes the
surface.
B. off a surface at a greater angle than it strikes
the surface.
C. off a surface at different angles than it strikes
the surface.

A. off a surface at the same angle it strikes the surface.

Explanation:

The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi

So, if a wave hits a mirror at an angle of 36°, it will be reflected at the same angle (36°)

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
