When light is refracted, the degree of bending is determined in part by?

Refraction happens when there is a bending of path of a light wave as it passes across the boundary separating two media and the degree of bending is determined in part by the total change in velocity as the light passes from one medium to the other. In addition, the change in speed experienced by a wave when it changes medium can result in a number of beautiful optical effects. 

not sure but try c two haploid cells

explanation:

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
