This chart shows how organisms are classified by their characteristics.

Question

A diagram titled Classification of Animals shows a tree of images and names of animal ancestry. A diagram, labeled Classification of Animals, shows images of animals under different groups. From left to right, top to bottom: ● Classification of Animals to Vertebrates ○ Vertebrates to Warm-Blooded ■ Warm-Blooded to Mammals ● Mammals to bear, tiger, whale ■ Warm-Blooded to Birds ● Birds to ostrich, peacock, eagle ○ Vertebrates to Cold-Blooded ■ Cold-Blooded to Fish ● Fish to salmon, goldfish, guppy ■ Cold-Blooded to Reptiles ● Reptiles to turtle, crocodile, snake ■ Cold-Blooded to Amphibians ● Amphibians to frog, toad, newt ● Classification of Animals to Invertebrates ○ Invertebrates to With Jointed Legs ■ With Jointed Legs to with 3 pairs of legs ● With 3 pairs of legs to ant, cockroach, lady ■ With Jointed Legs to with more than 3 pairs of legs ● With more than 3 pairs of legs to scorpion, spiders, millipede ○ Invertebrates to Without Legs ■ Without Legs to Worm-like ● Worm-like to earthworm, leech ■ Without Legs to Not-worm like ● Not-worm like to fluke worm, tapeworm.

Based on this diagram, which two groups of organisms share the most similar DNA?

warm-blooded and cold-blooded

Answer 1

Based on the diagram provided, the two groups of organisms that share the most similar DNA are turtles and frogs. Both turtles and frogs are classified as cold-blooded vertebrates but belong to different classes (Reptiles and Amphibians, respectively).

While warm-blooded and cold-blooded organisms are categorized based on their physiological traits, their DNA may not be as closely related as those within the same taxonomic groups like turtles (Reptiles) and frogs (Amphibians).

Thus, the correct answer is turtles and frogs.
