If you shine a laser pointer into an ice cube, which of the following properties will cause the laser light to bend as it enters the ice cube? a. scattering
b. refraction
c. absorption
d. reflection

The correct answer is (b) Refraction

When a beam of light is passed from one medium to another medium then the beam of light bends when it passes from one medium to other, this phenomenon is called as Refraction. This change can be determined by measuring the change in the wave speed and the initial direction of wave relative to the direction of the change in speed. Example: when a beam of light is passed through a prism, when a laser light is passed through a ice cube.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
