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.

Input: Consider Input: Question: Do gene expression and genetic analysis reveal diverse causes of recessive self-compatibility in Brassica napus L?
Answer: The recessive SC in eight accessions is caused by the loss of function of BnSCR-7 and BnSCR-6 in pollen. Translational repression contributes to the recessive SC in three accessions, whose SRK and SCR genes were expressed normally and had identical CDSs to BrS-29 or BoS-15. SI in 11 F1 hybrids relies on the expression of BnSCR-1300 rather than SRK genes. Other factor(s) independent of the S locus are involved in recessive SC. Therefore, diverse causes underlie recessive SC in B. napus, yielding insight into these complex mechanisms.

Output: yes


Input: Consider Input: Question: Do divergent growth strategies between red algae and kelps influence biomechanical properties?
Answer: We propose that divergent patterns in the distribution of material properties along blades may have different consequences for the performance of kelps and red algae. The positioning of younger tissues at the blade base for kelps may enable these species to attain larger body sizes in wave-swept habitats.

Output: yes


Input: Consider Input: Question: Are protective effects of N-acetyl-L-cysteine and platelet activating factor inhibition linked to intercellular adhesion molecule-1 expression after intestinal ischemia and reperfusion injury in rats?
Answer: The protective effect of NAC and the PAF inhibitor Lexipafant in intestinal I/R injury is not due to a decreased expression of ICAM-1.


Output: no
