This phylogenetic tree shows a relationship of all of these organisms. What trait is most likely found at 2? Select one: a. Have a backbone b. Have live offspring c. Made up of cells d. Live on land

A. have a backbone

Explanation:

You can simply use the process of elimination for this. We know that tuna have a backbone, so that is an option. We know they lay eggs, so B isn't an option. As far as C, every living thing is made up of cells, including the lamprey, so it isn't that. Finally, tuna don't live on land. The only one left is A.

a: the sheep and waste material both release carbon into the atmosphere.
