A researcher wanted to determine if a sample of DNA belonged to an animal, or plant, or bacteria, or fungi, or unknown organism. What gene would provide evidence that the DNa came from an animal cell? gene for synthesis of energy molecule ATP (B) gene for encoding the starch cellulose gene for production of the protein collagen (D) gene for production of peptidoglycan for cell wall Question 2 Starfish (an echinoderm) and jellyfish both have radial symmetry, but humans are more closely related to the starfish than jellyfish are. What evidence supports this? Humans have radial symmetry during most of their embryonic development Starfish undergo similar embryonic stages as humans during developmet (blastula, gastrula), and show bilateral symmetry in the larval stage, but later develop radial symmetry as adults. Jellyfish are always radially symmetrical. Jellyfish have bilateral symmetry, and also have triploblastic larvae Both starfish and humans have diploblastic development during embryonic stages..
