"Unfertilized eggs are stored in ootheca" is incorrect about a cockroach. The correct option is (4) Unfertilized eggs are stored in ootheca.
Explanation:
- Female cockroaches produce eggs and store them in an egg case called "ootheca".
- This egg case contains about 16 fertilized eggs which are divided into two rows with the arrangement of 8 eggs in each row.
- Thus, Unfertilized eggs are stored in the ootheca is incorrect about a cockroach.
