Edgar is stranded on an island surrounded by an ocean of salt water. he is thirsty, but he knows that it is a bad idea to drink salt water. how could edgar separate the salt out of the salt-water mixture?

Sea water is just water, with a higher mineral concentration (salt). Therefore, it is not healthy because minerals are good for us,but not in such concentrations. So that he can drink the water, he needs to somehow separate the salt from the water.

How?

He could use a process called distillation where he would boil the salt water, collect the vapor that comes out and condense it so that he can drink it.

If he was not in anisland though, I would've suggested other more scientifical but easier methods such as using reverse osmosis, which would only work on a lab or with special equipment.

Hope it helped,

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.
