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.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer:

All chordates have notochord 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, “both b and c.”

All chordates have notochord. However, all chordates do not possess jaws. 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.
