Based on the information in the table, the best prediction about the amino acid sequences of the protein produced by flowering plants, cone-producing plants, and green algae is:
The amino acid sequences for flowering plants and cone-producing plants will be the most similar.
This prediction is supported by the fact that flowering plants and cone-producing plants share a more recent common ancestor (250 million years ago) compared to the common ancestor they share with green algae (500 million years ago). As a result, the amino acid sequences of the proteins produced by flowering plants and cone-producing plants are likely to be more similar to each other than to those of green algae.
