Rabbits, chickens, tortoises. and fish are equally related to each other.

Answer 1

To provide an accurate answer, I would need to see Figure 1, which shows the embryo development for the four organisms. However, based on typical patterns of vertebrate embryology, I can offer some general guidance on how to evaluate the statements:

A. This rests on the idea of phylogenetic relationships observed in embryonic stages. If chickens share more similarities in early embryonic development with tortoises compared to rabbits, this might be true, but any conclusion would require direct observation of the figure.

B. This statement seems unlikely, as vertebrates generally show varied levels of relatedness based on embryonic development stages. Typically, closely related organisms exhibit more similarities.

C. This is generally incorrect. Fish do share a common ancestor with other vertebrates, but whether the figure supports or contradicts this depends on specific details in the embryo illustrations.

D. If the figure illustrates significant differences in the embryonic development of fish and chickens relative to each other compared to other organisms, this could be a stickout conclusion.

Please refer to the specific details in Figure 1 to determine which statement can be best supported.
