The correct Answer is:
To answer the question regarding the loop-like broad vessels without valves found in the 10th and 11th segments of an earthworm, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Structure**: The question specifies that we are looking for loop-like broad vessels located in the 10th and 11th segments of the earthworm's body. 2. **Characteristics of the Vessels**: The vessels mentioned are described as broad, loop-like, thin-walled, and non-pulsating. Importantly, they are noted to be without valves. 3. **Understanding Earthworm Anatomy**: In earthworms, the circulatory system consists of various vessels, including dorsal and ventral blood vessels, as well as other specialized structures. 4. **Specific Function of the Vessels**: The vessels in question serve a specific function in the circulatory system of the earthworm, particularly in the anterior part of the body. 5. **Correct Terminology**: Based on the characteristics and location of these vessels, they are specifically referred to as "anterior loops." 6. **Conclusion**: Therefore, the vessels located in the 10th and 11th segments of the earthworm, which are loop-like, broad, and without valves, are known as **anterior loops**. ### Final Answer: In earthworm, the loop-like broad vessels without valves found in the 10th and 11th segments are known as **anterior loops**. ---

There are two vessels. Each of them contains one moles of a monoatomic ideal gas. Initial volume of the gas in each vessel is 8.3 xx 10^(-3) m^(3) at 27^(@)C . Equal amount of heat is supplied to each vessel. In one of the vessels, the volume of the gas is doubled without change in its internal energy, whereas the volume of the gas is held constant in the second vessel. The vessels are now connected to allow free mixing of the gas. Find the final temperature and pressure of the combined gas system.

Three closed rigid vessels, A, B and C, which initially contain three different gases at different temperatures are connected by tube of negligible volume, without any energy transfer with surroundings. The vessel A contain 2 mole Ne gas, at 300 K, vessel 'B' contain 2 mole SO_(2) gas at 400 K and vessel 'C' contain 3 mole CO_(2) gas at temperature 500 K. What is the final pressure (in atm) attained by gases when all valves of connecting three vessels are opened and additional 15.6 kcal hear supplied to vessels through valve. The volume of A, B and C vessel is 2, 2 and 3 litre respectively Given :R =2 calorie/mol-K, C_(v)(Ne)=3//2R,C_(v)(CO)=5//2R and C_(v)(SO_(2))=3R
