Answer 1

Textbook Question

Chapter 24, Problem 1SA

All chordates have (a) _______ as embryos.

a. backbone

b. jaws

c. notochord

d. kidneys

Expert Solution & Answer

Summary Introduction

Introduction:

Embryo development is a crucial step for ensuring the survival of any species. Initial development is similar for both vertebrates and invertebrates. As the embryo continues to develop, the specific characteristics of the species emerge at different stages.

Answer to Problem 1SA

Correct answer:

All chordates have notochords as embryos. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Option c. is given as “notochord.”

As the embryo continues to develop, the ancestral characteristics are seen in the embryo and later specific characteristics of the species emerge at different stages. The nerve cord, notochord, postnatal tail, and pharyngeal slits are the four characteristics that are present in the chordates.

Reason for incorrect answer:

Option a. is given as, “backbone.”

Backbone is the property of vertebrates and all chordates are not vertebrates. So, the embryo of all chordates does not have a backbone. Hence, option a. is incorrect.

Option b. is given as, “jaws.”

Jaws are the characteristic feature of vertebrates and all chordates are not vertebrates. Hence, option b. is incorrect.

Option d. is given as, “kidneys.”

Kidneys are present in vertebral class under vertebrates and it is not the property of invertebrates and chordates include both vertebrate and invertebrates. Hence, option d. is incorrect.

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

Conclusion

The ancestral characteristics are visible during the development of the embryo and the presence of notochord is the characteristic feature of chordates both invertebrates and vertebrates. Thus, the correct option is c.
