Which of the following features enables the tapeworm to live successfully in the small intestine of human?
Answer Details
The feature that enables the tapeworm to live successfully in the small intestine of human is "Hook and suckers for strong attachment". Tapeworms are long, ribbon-like parasites that attach themselves to the walls of the small intestine using hooks and suckers on their head called scolex. These hooks and suckers enable the tapeworms to anchor themselves securely in the small intestine, where they can absorb nutrients from the food being digested. The other options listed are not correct because:
- Along neck for forming young proglottis: This is not a feature that enables tapeworms to live successfully in the small intestine. The proglottids are segments that contain both male and female reproductive organs and are produced by the tapeworm's neck, but they are not necessary for survival in the small intestine.
- The absence of segmentation and appendages: This is a general characteristic of tapeworms, but it is not what enables them to live successfully in the small intestine.
- Possession of flame cells for excretion: Flame cells are found in flatworms, but they are not specific to tapeworms and do not enable them to live successfully in the small intestine.
