Teeth in Amphibians are(a) Homodont, Pleurodont, Diphyodont(b) Thecodont, Heterodont and Diphyodont(c) Homodont, Pleurodont and Polyphyodont(d) Homodont, Thecodont, and Polyphyodont

The correct answer is: (c) Homodont, Pleurodont, and Polyphyodont

Here’s the detailed explanation:

Homodont: Amphibians typically have teeth that are uniform in shape, meaning they are homodont. This means all their teeth are similar, unlike in mammals where teeth may vary in shape (incisors, canines, molars).

Pleurodont: Amphibians usually have pleurodont teeth, meaning the teeth are attached to the inner side of the jaw. This is in contrast to thecodont teeth (where the teeth are set in sockets), which are found in mammals and some reptiles.

Polyphyodont: Amphibians are polyphyodonts, meaning they continuously regenerate or replace their teeth throughout their lives. Unlike humans, who are diphyodont (have two sets of teeth), amphibians can replace their teeth multiple times.

Thus, the correct combination of characteristics for amphibian teeth is homodont, pleurodont, and polyphyodont.
