Compared with a smaller cell, a larger cell of the same shape has less surface area. a. the same surface-to-volume ratio. b. less surface area per unit of volume. c. a smaller average distance between its mitochondria and the external source of oxygen. d. a smaller cytoplasm-to-nucleus ratio.

less surface area per unit of volume

Explanation:

The surface area and volume of a cell vary with its size. A large cell has larger has a larger surface area compared to the smaller cell of the same shape. As the size of the cell increases, there is a greater increase in the surface area than that in the volume of the cell. This results in a lower surface area to volume ratio for a larger cell than that for a smaller cell of the same shape.

The surface area to volume ratio affects many vital processes such as diffusion of substances, heat exchange, etc. Cells maintain a smaller size to have a higher surface area to volume ratio which in turn increases the rate of diffusion of substances.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
