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.

The light oils (like gasoline) tend to evaporate into the air, and if the spill is all light, the oil will disappear (into the air) by itself. Some of the oil mixes with the water forming an emulsion where everything mixes together because of the waves (think of shaking up a jar of oil and vinegar).
