Flowering plants have common ancestors with other plants and plant-like organisms. The table below shows the last common ancestor shared between flowering plants and two other types of organisms.
Last common ancestor with flowering plants
Cone-producing plants 250 million years ago
Green Algae 500 million years ago
A scientist compares the amino acid sequences of a protein produced by flowering plants, a cone-producing plant, and green algae.
What prediction about these sequences is supported by the data in the table?

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.
