SA:V refers to . The bigger the object the the SA:V

Cells have a SA:V because they are small which allows them to maintain 9. by moving necessary 10. in and out of the cell.

My

1. Surface area:volume ratio

2. Smaller

3. Large

4. Homeostasis

5. Substances

Explanation:

SA:V is used to connote Surface area to volume ratio. In biology, SA:V is the surface area per unit volume of a cell or surface. The importance of surface area:volume in cells cannot be overemphasized because it allows materials to be able to enter and leave the cell.

The bigger/larger the object or cell, the smaller the SA:V (Surface area to volume ratio). Cells in living organisms have a LARGE SA:V because they are small which allows them to maintain HOMEOSTASIS by moving necessary MATERIALS/SUBSTANCES in and out of the cell.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it
