For example, you could ask:

* "How do nerve cells and muscle cells function differently in the same organism even though they both contain genetic instructions?"

* "How do skin cells and blood cells function differently in the same organism even though they both contain genetic instructions?"

Once you provide the cell types, I can explain how they function differently despite having the same DNA.

The key is that cells express different genes, leading to the production of different proteins. These proteins are responsible for the unique structures and functions of each cell type.
