What is the procedure/variables for the plate tectonics lab

The Theory of Plate Tectonics states that the crust of the Earth is composed of seven major

plates and numerous smaller plates. These plates “ride” on the hot plastic upper mantle called

the asthenosphere. This theory also says that most of these plates are in motion, creating

a variety of interactions at the plate boundaries. As plate boundaries, plates may converge,

diverge, or slip (lateral) past each other in a horizontal motion. In addition, some plates may

appear to be inactive.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
