Answer 1

2 is the answer hope helped

Answer 2

Amphibians have eyelids and a tympanum is present instead of an ear.

• The tympanum is made up of nonglandular skin. It is located behind the eye.
• It does not process sound waves, it simply transmits them to the inner part of the amiphibian's ear.
• This inner ear is protected from the entry of water and other foreign objects.
• Amphibians have a regular set of eyelids. The bottom lid stays still and the upper lid blinks.
• Frogs also have a third eyelid that serves a different function.
