Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Q: Question: Is low serum bilirubin concentration a predictor of chronic kidney disease?

A: yes

Q: Question: Does expression of the pair-rule gene homologs runt , Pax3/7 , even-skipped-1 and even-skipped-2 during larval and juvenile development of the polychaete annelid Capitella teleta support a role in segmentation?
Answer: C. teleta eve, Pax3/7 and runt homologs all have distinct expression patterns and share expression domains with homologs from other bilaterians. None of the pair-rule orthologs examined in C. teleta exhibit segmental or pair-rule stripes of expression in the ectoderm or mesoderm, consistent with an independent origin of segmentation between annelids and arthropods.

A: no
