Passage I

The whitefly Bemisia argentifolii is an insect that has 3 distinct life stages: egg, nymph ( juvenile), and adult. A study examined the effects of external temperature on the duration of each of the 3 life stages of B. argentifolii and on egg production by adult female B. argentifolii. Figure 1 shows, for each of 5 external temperatures, the average duration of each life stage. Figure 2 shows, for each of the 5 temperatures, the average number of eggs produced per female per day during the first 7 days of adult life.

3. Consider the statement “The temperature that resulted in the shortest average duration of the egg stage was also the temperature that resulted in the longest average duration of the adult stage.” Is this statement consistent with the results shown in Figure 1 ?

Answer and Explanation

Your Answer is

Correct Answer is D

Explanation

According to Figure 1, it can be seen that the minimum value of the egg stage is at 30°C, and the maximum value of the adult stage is at 20°C, which is consistent with D
