Which one of the following statements is true?a)All organ system leve...
Statement: All organ system level animals have a tube within tube plan
Explanation:
- Organ system level animals are those that have specialized organs and systems working together to carry out various functions in the body.
- The tube within tube plan refers to the presence of two interconnected tubes in the body - the outer tube is the body wall and the inner tube is the gut or digestive tract.
- This arrangement allows for the specialization of different regions of the gut for different functions such as digestion, absorption, and elimination of waste.
Examples of animals with tube within tube plan:
1. Humans: The digestive system consists of the mouth, esophagus, stomach, small intestine, and large intestine, which form a continuous tube for the passage of food.
2. Earthworm: It has a long digestive tract with specialized regions for digestion and absorption.
3. Insects: They have a digestive system consisting of a foregut, midgut, and hindgut, each with specific functions.
Reasoning behind the true statement:
- All organ system level animals require a specialized digestive system to efficiently process and absorb nutrients.
- The tube within tube plan is an efficient and organized arrangement that allows for the separation of functions and enhances the digestive process.
- Therefore, it can be concluded that all organ system level animals have a tube within tube plan.
Conclusion:
Hence, the true statement is "All organ system level animals have a tube within tube plan" (Option A). This is because the presence of a specialized digestive system with a tube within tube plan is a characteristic feature of organ system level animals.

All organ system level animals have a tube within a tube plan involving two tubes or openings. This plan calls for two openings: one for food to enter the body (mouth), one for wastes to leave the body (anus). Aschelminthes are the first organisms to show this type of body plan.
