Chapter 40, Problem 1SQ

Summary Introduction

Introduction: Most animals have excretory organs with a tubular structure. Body fluids enter into the one end of the tube. As these fluids enter through the tube, water and essential solutes leave the tube and return to the body fluid. Waste continues to the end of the tube and is eliminated from the body.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer:

Option c. is given as “Malpighian tubules”. It removes the nitrogenous waste.

Therefore, optionc. is correct.

Explanation of Solution

Reasons for the correct statement:

Malpighian tubules are tubular excretory organs that deliver nitrogenous waste and other substances to the waste-processing portion of the digestive tract.

Hence, optionc. is correct.

Reasons for the incorrect statements:

Option a. is given as “nephridia”. A nephridium takes up coelomic fluid, adjusts its content, and releases waste through a pore in the body wall.

Therefore, option a. is an incorrect answer.

Option b. is given as “nephrons”. Nephrons are tiny tubules present in the kidney that produce urine.

Therefore, option b. is an incorrect answer.

Option d. is given as “contractile vacuoles”. The contractile vacuole that is present in the cell involves in osmoregulation.

Therefore, option d. is an incorrect answer.

Hence, options a, b., and d. are incorrect answers.

Conclusion

An insect’s malpighian tubules deliver nitrogen-rich waste to its gut.
