The Fleischmann’s glass frog (*Hyalinobatrachium fleischmanni*) exhibits a unique adaptation to evade predators during sleep. Researchers have found that while sleeping, the frog sequesters approximately 89 percent of its red blood cells within its liver. Because the frog's skin and muscles are translucent, hiding these pigment-rich red blood cells makes the frog's body nearly transparent, allowing it to blend seamlessly into surrounding leaves. Once the frog wakes up and becomes active, the red blood cells exit the liver and resume circulation throughout the body, restoring its typical color and activity levels.
Based on the text, what is true of a Fleischmann's glass frog when it is awake and active?
- AIt stores most of its red blood cells in its liver.
- BIt alters the pigment of its skin to blend into surrounding leaves.
- Its red blood cells exit the liver and circulate through its body.Cevap
- DIt becomes completely invisible to predators while moving.
Cevap
Its red blood cells exit the liver and circulate through its body.
The passage explicitly states that when the glass frog wakes up and becomes active, its red blood cells exit the liver and resume circulation throughout the body. Therefore, the option describing this process is directly supported by the text.
