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.

As you get farther from the light source the amount of light drops exponentially, so mirrors 10 feet from a bulb may only receive 10 percent of the usable light energy so the reflection at this point will be a little less than 10 percent of the original power. Then this 10 percent reflected drops exponentially again.
