Passage I
In a study of fur pigmentation in deer mice, Peromyscus polionotus, scientists compared the brightness of the fur of mice from populations located different distance directly inland from a coastal site. Figure 1 shows 2 facial regions and the 2 body regions at which the fur of each mouse was evaluated (on a scale from 0 to 1.00) with respect to its brightness. Figure 1 also shows how, for each of the 4 regions, average relative brightness varied with inland distance.
Figure 2 shows how the average brightness of surface soil samples, given as the average percent relative reflectance, varied with inland distance.
6. Based on Figure 2, on average, was the surface soil at the coastal site lighter or darker than the standard that was used for the comparison?
Your Answer is
Correct Answer is J
Explanation
Through figure 2, it can be seen that the coastal site, that is, when the inland distance is 0 km, the ordinate reflectance is nearly 75&%;
The figure below shows that the comparison standard is 100%, so the coastal site 75% smaller and darker than standard
