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.
It speeds up. Air and water are both media (plural form of medium). Each one of them has a different speed of light. As the incident ray passes from air to water, it refracts to be closer to the normal. A refraction occurs when there is a change in the speed of light.A change in the speed of light occurs when there is a change in media. In this case the media is changed from air to water.hen light passes from air to water, glass or plastic, the light ray Refracts meaning it bends towards the medium (The middle) â¦ . However this is only the case when the second material the light passes through is denser than the original.
