Why is it necessary for the genetic material in a cell to exist in chromatin form during normal cellular activity, and not in chromosome form? chromatin prevents genetic material from being broken off during replication. it requires more surface area in the cell to have the cells condense. condensing into chromosome form requires more energy than the cell has to exert. chromatin form allows the genetic code to be read and proteins to be made.

The sketch shows a rynchosaur, an extinct animal that is known only from fossils. there has been much debate about the classification of these creatures. some scientists suggest that they belong with primitive amphibians, and some think they are related to snakes and lizards.the data equally support both cases. which statement best explains how to draw a cladogram that includes the rynchosaur? draw the cladogram for amphibians. draw the cladogram for reptiles. draw two cladograms, both showing the traits, and leave it as a hypothesis. draw two cladograms, both showing the traits, and have scientists vote
