Question

Segmentation of Earth Worm is very to:

• A. 10-20
• B. 5-10
• C. 100-150
• D. 150-200

Hint:

The segmented body of an earthworm plays a critical role in its movement, with each segment containing muscles that contract and expand to help propel the worm through soil.

Answer 1

The Correct Option is C

The earthworm exhibits metameric segmentation, which means its body is divided into a series of segments, with each segment containing similar organs and structures. This segmentation is crucial for the earthworm’s locomotion and other functions.
Typically, an earthworm has 100-150 segments along its body.
10-20 segments would be too few for an adult earthworm.
5-10 segments would also not reflect the characteristic segmentation in a mature earthworm.
150-200 segments would be larger than what is typically found in most earthworm species.

Thus, 100-150 segments is the typical number of segments found in an earthworm.
