Question

Chapter 33, Problem 1SQ

Summary Introduction

Introduction:

The vertebrates are the organisms that are characterized by the presence of the solid backbone which is a bony structure that extends from the neck to the abdomen. It is absent in the invertebrates which makes them easily distinguishable from the vertebrates.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer:

The unique feature regarding the circulatory system of vertebrates is that it is a closed circulatory system. The blood is confined in the blood vessels and is circulated from the heart to the body and reverse. The closed circulatory system is present in mammals and fishes. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

Option a. is given as, “closed circulatory system.”

The invertebrates have an open circulatory system in which the blood is present freely in the body cavity while in the vertebrates it is confined in the blood vessels

Reason for incorrect answer:

Option b. is given as, “two-chambered heart.”

The vertebrates can have two, three or four-chambered heart. The number of chambers in the heart is not the defining feature of vertebrates. Hence, option b. is incorrect.

Option c. is given as, “lungs.”

Not all vertebrates have lungs. The fishes respire through gills, and they are members of vertebrates. So, the presence of the lungs does not define the vertebrates. Hence, option c. is incorrect.

Option d. is given as, “all of the above.”

All vertebrates have only a closed circulatory system. Hence, option d. is incorrect.

Hence, the options b., c., and d. are incorrect.

Conclusion

The presence of a closed circulatory system is a unique character of vertebrates. The vertebrates contain blood vessels, capillaries and a pumping organ known as the heart in their circulatory system. Thus, the correct option is a.
