Question

organisms with very similar proteins are more closely related than organisms with less similar protein structures. what type of evidence is this?○ embryology○ molecular○ anatomical○ fossilquestion 6 10 ptswhy would a platypus (mammal) and a duck (bird) have a bill for their mouths?○ because of convergent evolution.○ because of biogeography.○ because of anatomical similarities.○ because of divergent evolution.

Explanation:

For the first question: Proteins are molecular-level structures, so using protein similarity to determine relatedness is molecular evidence. Embryology focuses on embryonic development, anatomical on physical body structures, and fossil on preserved remains, which do not apply here.
For the second question: Convergent evolution occurs when unrelated species develop similar traits due to adapting to similar environments/niches. Platypuses and ducks are not closely related, but their bills evolved for similar feeding needs. Biogeography focuses on species distribution, anatomical similarities are a result not a cause here, and divergent evolution produces different traits from a common ancestor, which does not fit.

Answer:

1. Molecular
2. Because of convergent evolution.
