And today i'll be helping you with the fourth problem of the chapter 29 problem set.
00:07
And this is asking which of the following is not a characteristic of a vertebrate.
00:11
So how i'd approach this is i would try to list all of the characteristics or traits.

I'm just putting abbreviation, so i don't have to write at all.
00:40
And then they have internal organs...
