Answer:False
Step-by-step explanation:
False. Earthworms have more than two sets of muscles inside their bodies. In fact, they have three main types of muscles:
1. Circular Muscles: These are also known as annular muscles, and they run in circles around the earthworm's body. When these muscles contract, the worm becomes longer and thinner.
2. Longitudinal Muscles: These muscles run along the length of the earthworm's body. When they contract, the worm becomes shorter and thicker.
3. Diagonal Muscles: These muscles are arranged diagonally between the circular and longitudinal muscles. They allow the earthworm to control its movement more precisely.
The coordinated action of these three sets of muscles allows the earthworm to move through the soil by alternating between contracting and relaxing its muscles, enabling it to burrow and crawl.
