Question

this boomslang snake is swallowing a frog. boomslang snakes can use their fangs to inject venom into their prey. but like other snakes, boomslang snakes do not have teeth that they can use to chew their food. instead, snakes swallow their prey whole. snakes have a flexible esophagus that helps them take in whole food. what can a snakes esophagus do? a snakes esophagus can tear whole prey into small pieces. a snakes esophagus can digest whole prey quickly. a snakes esophagus can stretch around whole prey and push the prey from the mouth to the stomach.

Explanation:

The text clearly states that snakes have a flexible esophagus that helps them take in whole food. This means the esophagus can stretch around the whole prey and push it from the mouth to the stomach. The first option is incorrect as snakes don't chew (no teeth for chewing), so the esophagus can't tear prey. The second option is wrong because the text doesn't mention digestion speed of the esophagus; it's about taking in (swallowing) whole prey.

Answer:

A snake's esophagus can stretch around whole prey and push the prey from the mouth to the stomach.
