Answer:
Polyploid cells have more than 2 sets of each chromosome. Hope that helped! :)
Answer:
What Keene High school students are you reading about? And what scientist are you talking about? If you had given more information I would have helped. Anyways, just look at what it says in the book that the scientist did, and what the Keene high school students did. And see what they both have in common.
Fish poop.
Tropical white beaches get their pearly white color from the excrement of fish far off of the coast which eat coral and other things that reside on the ocean floor. When they eat they swallow some sand into their mouths as well, and process it with the food they just ate. Their stomachs can't really digest the sand, tiny minute rocks essentially, and thus turn their color white. Or the rock forming the sand can be naturally pigmented a whitish tone as well.
Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.
