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.
This is due to the fact that the index of refraction of water is greater than air. This happens behind flat surfaces, such as your mask, a compact camera underwater housing, or a macro port. It does not happen when using a dome port.he colors disappear underwater in the same order as they appear in the color spectrum. Even water at 5ft depth will have a noticeable loss of red. For this reason, strobes are usually used to add color back to subjects.
