A group of scientists placed four groups of icefish embryos (group of cells that will become a baby) into water tanks at various incubation (heat) temperatures. After 24 hours, they counted to see how many embryos developed normally and how many had some type of mutation damage. Their results are shown below.

What can scientists conclude about the effect of temperature on developing icefish embryos?

Which is the best explanation for why these cells perform different functions if their nucleus contains the same DNA?

How does DNA relate to gene expression and cell differentiation?
