Passage II
In the python (Python molurus), a species of snake, organ mass and metabolic rate may decrease between meals, conserving energy. Figure 1 shows, for a group of juvenile pythons (Group V), the average mass of the small intestine before and after each python ingested a single meal that had a mass equal to 25% of the python’s body mass. Figure 2 shows, for 4 groups of juvenile pythons (Groups W−Z), the average oxygen consumption rate, in milliliters of oxygen consumed per gram of body mass per hour (mL/g/hr), before and after each python ingested a single meal. Table 1 shows the relative mass of the meal ingested by the pythons in each group.
13. Suppose the average oxygen consumption rate of the Group V pythons had been determined 1 day after they ingested their meal. Based on Table 1 and Figure 2, the oxygen consumption rate would most likely have been:
Your Answer is
Correct Answer is B
Explanation
The python's body mass of Group V is 25%. According to Table 1, it can be seen that it is between Group Y and Z, so it should correspond to the value of Day 4 between the two in Figure 2, so it is B
