Q. Poison glands of snakes are homologous to
✅ Correct Answer: (D)
salivary glands of vertebrates
Explanation:
- Homologous structures are those that have a common evolutionary origin but may serve different functions.
- The poison glands of snakes evolved from salivary glands in vertebrates.
- In snakes, these glands have been modified to produce venom, which is delivered through specialized fangs.
- In other vertebrates, salivary glands primarily help in digestion and lubrication of food.
Thus, the poison glands of snakes are homologous to the salivary glands of vertebrates.
