Question

the forelimb of a chicken and a primate contain many of the same bones arranged in the same order. this is an example of
○ limb sharing.
○ tetrapodology.
○ homology.
○ similarity.
○ comparable limbs.

Explanation:

Homology refers to structures in different organisms that share a common embryonic origin, even if their functions differ. The forelimbs of a chicken and a primate have the same bone arrangement due to shared ancestry, which fits the definition of homology. Other options are incorrect: "limb sharing" and "comparable limbs" are not scientific terms; "tetrapodology" is the study of tetrapods, not the structure itself; "similarity" is too vague and not a specific biological concept for this context.

Answer:

homology.
