Question

A protist has a surface area-to-volume ratio of 5:1. A human intestinal cell has a surface area-to-volume ratio of 2:1. Which of the following statements is true? The intestinal cell is more efficient at expelling wastes because it has a high surface area-to-volume ratio. The protist is more efficient at expelling wastes because it has a higher surface area-to-volume ratio. The intestinal cell is more efficient at procuring nutrients because it has a lower surface area-to-volume ratio. The protist is more efficient at procuring nutrients because it has a lower surface area-to-volume ratio.

Answer 1

The protist is more efficient at expelling wastes because it has a higher surface area-to-volume ratio.

Step-by-step explanation:

According to the given information, protists have more surface area to volume ratio as compared to a human intestinal cell. More surface area to volume ratio refers to the fact that more of the surface area of the organism is in contact with surroundings. A cell or organism with a greater surface exposed to surroundings has a higher rate of exchange of materials or heat with the outer environment. Having a greater surface area of the body exposed to the surroundings, protists are able to release the waste out of the body more efficiently as compared to the small intestine.
