Answer 1

Hello! I hope these answers are right. For Q1, it should be a barb fish, and for Q2, it'd be a newt. :3

Step-by-step explanation:

For Q1, the barb fish seems to be the correct answer because among fish and (i believe) most other vertebrates, pharyngeal arches are developed structures which support their gills; along with gill and branchial arches! :>

For Q2, the newt is the correct answer, as a newt is a chordate. Many chordates develop postanal tails in the embryonic stage; it's just a characteristic of them!

I hope this helped! :D
