Nutrient uptake and diffusion of molecules into the bacterial cell become more efficient as the surface area-to-volume ratio

Increases

Explanation:

The relationship between the surface area-to-volume ratio and nutrient uptake and diffusion of molecules into the bacterial cell is direct because increase in one (surface area-to-volume ratio) leads to a corresponding increase in efficiency in the other (nutrient uptake and diffusion of molecules into the cell)
