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.

1 Light traveling from a less dense to a more dense medium refract towards the normal. 2  This behavior is exhibited by light moving from air into water. 3  The greater the difference in density between the two media, the greater the refraction.4  The greater the incident angle, the greater the refraction.efracted light rays behave in the following ways: 1  Light traveling from a more dense to a less dense medium refract away from the normal. 2  This behavior is exhibited by light moving from water to air. 3  Light traveling from a less dense to a more dense medium refract towards the normal.
