Question

5 small cells function more effectively, because as cells become larger their surface area to volume ratio. multiple choice increases. decreases. is cubed. is squared. stays the same

Explanation:

As cells grow larger, their volume increases more rapidly than their surface - area. The surface - area to volume ratio is calculated as $\frac{\text{Surface Area}}{\text{Volume}}$. With volume increasing at a faster rate, this ratio decreases. This is important for cell function as a higher surface - area to volume ratio allows for more efficient exchange of materials like nutrients and waste across the cell membrane.

Answer:

B. decreases
