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.
Refraction can make things look closer than they really are. The difference in speed between light traveling through water and through air means that, from the surface, a 13-ft (4-m) pool appears to be just 10 ft (3 m) deep. Glass is another material that refracts light.It is used to make eyeglasses and other lenses.he difference in speed between light traveling through water and through air means that, from the surface, a 13-ft (4-m) pool appears to be just 10 ft (3 m) deep.
