The key (for the host: fold this page back)
- B: alveoli. Each person has hundreds of millions of alveoli in their lungs.
- A: P waves. P stands for primary; the slower S, or secondary, waves arrive later.
- A: cardenolides. These toxins help keep monarchs safe from animals that might eat them.
- B: the epidermis. Below it is the dermis, which holds nerve endings, blood vessels and sweat glands.
- B: Mount Chimborazo. Earth bulges at the equator, and Chimborazo sits just one degree south of it.
- B: algae. The grooves run from the top to the bottom of each brownish-gray hair.
- A: tendons. When a muscle pulls, its tendon and the bone move along with it.
- A: the Mariana Trench. It is about 10,935 meters deep, in the western Pacific Ocean.
- A: 13. Unlike most lemurs, ringtails spend about 40 percent of their time on the ground.
- C: 🦇 A bat. A riddle: every clue fits only one of the three.
