A cladogram is a chart which demonstrates cladistics. A branch point on a cladogram branches off from a common point in a cladogram, which shows that the two organisms share a common ancestor. Hope this helps! (:
Although in many regions of the brain—particularly those that give rise to nuclear cell groups—neurons migrate without the benefit of glial guides, migration along radial glial fibers is always seen in regions where cells are organized into layers, like the cerebral cortex, hippocampus, and cerebellum.
One: The cell is able to move material in and out of the cell
Two: It helps the cell maintain necessary conditions for life
I believe the answer is...a change in allele frequency over many generations!
Hope this helps!
