Based on Figures 2 and 3, which information explains how DNA is used to make specialized cells and tissues within the sea star?
Select all that apply.

Stem cells arise from smooth muscle cells.

Cells from the central disk can become any other type of cell.

When Gene 1 is on and Gene 2 is off, the cell becomes a nerve cell.

Smooth muscle cells regenerate new arms using mitosis and meiosis.

When Gene 1 is off and Gene 2 is on, the cell becomes a tube foot cell.
