1) explain how the surface area and volume of cells affect the rate of exchange of materials in and out of cells in multi cellular organisms.

The smaller the surface area of a cell the easier it is the allow nutrients to enter the cell and have wastes exist the cell quickly. less energy is used!

Cell division is important to single celled organisms because it allows the cells to reproduce. through cell division, cells make exact copies of themselves. when single celled organisms go through cell division, they make exact copies of themselves which is how they reproduce.

The moths will eventually become extinct
