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.
12. Based on Figure 2, the average metabolic rate for the Group W pythons was most likely greatest approximately how many days after they ingested their meal ?
Your Answer is
Correct Answer is F
Explanation
According to Figure 2, eating is on Day 3, and the Average metabolic rate is the Average oxygen consumption rate shown on the vertical axis (the concept of metabolism, which belongs to common sense), the highest is Day 5, so 5-3=2, choose F
