- ACows have sharp canines for tearing, tigers have flat molars for grinding.
- BCows have flat, broad molars for grinding plants, tigers have sharp canines for tearing meat.
- CCows have no teeth, tigers have all teeth sharp.
- DCows have teeth only in the lower jaw, tigers have teeth in both jaws.
Cows, as herbivores, have prominent flat, broad molars and incisors adapted for grinding tough plant material. Tigers, as carnivores, possess well-developed, sharp canines for tearing flesh and strong carnassial teeth for shearing meat.
