Compare Embryo Images Practice Test

Two embryo diagrams are shown for comparison across species. Each row shows a comparable developmental stage (Stage 1 and Stage 2). Use the visible evidence in the images to answer.

Which similarity between the embryos is supported by the evidence in the diagrams?

Two embryo images are shown for comparison across species. The embryos are at comparable early stages (Stage 1) and can be compared across species using visible features.

Based on the images, which similarity between the Stage 1 embryos is supported by evidence from the comparison?

Species labels: Species A (fish) and Species B (chicken).
