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.

Question

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?

(1 point)
Responses

The amino acid sequences for flowering plants and green algae will be the most similar.
The amino acid sequences for flowering plants and green algae will be the most similar.

The amino acid sequences for all three organisms will have no similarities.
The amino acid sequences for all three organisms will have no similarities.

The amino acid sequences for flowering plants and cone-producing plants will be the most similar.
The amino acid sequences for flowering plants and cone-producing plants will be the most similar.

The amino acid sequences for all three organisms will be identical.

Answer 1

The correct prediction supported by the data in the table is:

The amino acid sequences for flowering plants and cone-producing plants will be the most similar.

This prediction is based on the fact that flowering plants and cone-producing plants share a more recent common ancestor (250 million years ago) than flowering plants do with green algae (500 million years ago). As a result, it is expected that the amino acid sequences for flowering plants and cone-producing plants would be more similar due to their more recent shared evolutionary history.
