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.

the answer is b. glad to .

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
