Which of the following is incorrect regarding skeletal support system ...
Understanding Skeletal Support Systems
The skeletal support system varies significantly among different organisms, and option 'C' is incorrect regarding the features of snakes. Here’s an explanation of why this statement is inaccurate:
Earthworms' Liquid Skeleton
- Earthworms utilize a hydrostatic skeleton, where fluid-filled coelomic spaces provide support.
- This structure helps maintain body shape and enables movement through contraction of muscles against the liquid.
Skeletal Muscles Work in Pairs
- Muscles always function in antagonistic pairs; when one muscle contracts, the other relaxes.
- This mechanism is crucial for coordinated movement across various organisms, including humans.
Snakes and Their Movement
- The incorrect statement suggests that snakes have bristles on the undersurface for support, but this is not true.
- Snakes do not possess bristles. Instead, they rely on their flexible spine and scales for locomotion.
- Their movement involves slithering using muscle contractions and friction against the ground.
Birds' Hollow Bones
- Birds have evolved hollow bones with air-filled cavities, making them lighter for flight.
- This adaptation is essential for reducing body weight without sacrificing strength.
Conclusion
In summary, option 'C' is incorrect because snakes do not use bristles for movement; they depend on their unique anatomy and muscle coordination. Understanding these differences in skeletal systems helps appreciate how each organism adapts to its environment.
