Given four hypothetical taxa, construct a tree in which Taxon G is more closely related to Taxon L than to Taxon A, but all three of these taxa are more closely related to each other than Taxon F. The most obvious way to determine the evolutionary relationship of organisms (i.e. their phylogenetic tree) is compare morphological similarities
At this time, the concept of index of refraction should be discussed on relative terms. When a substance bends light more than another, it is said to have a higher index of refraction. Oil has a higher index of refraction than water or air.Assessment: Students' responses to key concepts and their responses to additional examples.t this time, the concept of index of refraction should be discussed on relative terms. When a substance bends light more than another, it is said to have a higher index of refraction. Oil has a higher index of refraction than water or air.
The index of refraction for red light in water is 1.331 and for blue light is 1.340. If a ray of white light enters the water at an angle of incidence of 83(, what are the underwater angles of refraction for the blue and red components of the light?7.. A light ray is partially reflected and partially refracted at a boundary between two media, the upper one having index of refraction n, the lower one having index of refraction n(, as shown in the figure.
