Question

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?

Answer 1

The 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 is because flowering plants and cone-producing plants share a more recent common ancestor (250 million years ago) compared to the common ancestor shared with green algae (500 million years ago). Similarity in amino acid sequences typically reflects the recency of a common ancestor, with more closely related organisms generally having more similar sequences.
