Passage III

As a living cell's surface area-to-volume ratio (S/V) increases, so does the cell's ability to exchange substances with its environment.

To model this exchange process, different-sized cubes of gelatin were immersed in a dye for 1 minute. Table 1 lists the edge length, surface area, volume, S/V, and per-cent volume of gelatin that was dyed.

Figure 1 shows the S/V of certain rectangular solids and spheres.

Figure 2 shows the volume of certain rectangular solids and spheres as a function of surface area.

Table 2 lists the diameter and surface area of 5 types of spherical ova (egg cells).

14. Ova with very large volumes tend to contain large amounts of nutrients that are used for growth by the embryo. Based on the information in Table 2 andFigure 2, which of the following ova most likely contain the greatest amount of nutrients?

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

In the question stem, it is given that the large egg cells contain more nutrients, so look at table 2. Among the options, Henova has the largest diameter, so it has the most nutrients
