Passage IV
Because amphibian eggs lack a hard outer shell, their DNA can be damaged by exposure to ultraviolet (UV) radiation in sunlight. Table 1 lists the egg-laying behavior of 7 amphibian species and the species’ relative ability to repair DNA damage caused by exposure to UV radiation.
Figure 1 shows the percent of eggs that survived to hatching in the lab for these 7 species after exposure to unfiltered sunlight or to sunlight from which the UV radiation had been filtered out.
Figure 2 shows predicted UV levels over time in 4 geographic regions that have amphibian populations.
22. According to the information in Table 1, for all the species shown, as the exposure of eggs to sunlight
increases, the relative ability to repair DNA damage generally:
Your Answer is
Correct Answer is G
Explanation
Looking at table 1, it is found that the more exposure of eggs to sunlight, the higher the relative ability to repair DNA damage
