Which statements about the phylogenetic tree are true? select all that apply?

The question is not complete, here is the completed part gotten from other website.

Mammals and turtles are more closely related than are lungfishes and sharks. Hagfishes, lungfishes, and frogs have lobed fins.

Lancelets and coelacanths are more closely related than are chimaeras and coelacanths.

Organism (a) is a common ancestor of all chordates.

Descendants of organism (d) have limbs with digits. birds and ray-finned fishes have a notochord and jaws.

rays and frogs have vertebrae. organism (c) is a common ancestor of lampreys and lungfishes?

The correct options are;

Mammals and turtles are more closely related than are lungfishes and sharks.

Descendants of organism (d) have legs.

Rays and frogs have a vertebral column.

-Birds and ray-finned fishes have a notochord and jaws

Explanation:

This is because phylogenetic tree is a branching diagram that entails different evolutionary relationships that occur between organisms or biological species having common decent or ancestors and showing similar and differences in their genetic characteristics or traits. It shows how species evolved from their ancestors.
