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.

Ex Input:
Question: Are biphasic redistribution of muscarinic receptor and the altered receptor phosphorylation and gene transcription underlying mechanisms in the rat heart during sepsis?
Answer: The m2AChR in the rat heart was externalized from light vesicles to sarcolemma (overexpression) during early sepsis but internalized from surface membranes to intracellular sites (underexpression) during late sepsis. Furthermore, changes in the receptor phosphorylation and gene transcription are responsible for the biphasic redistribution and the altered expression of m2AChR in the rat heart during the progression of sepsis.

Ex Output:
yes

Ex Input:
Question: Is reorganization of Azospirillum brasilense cell membrane mediated by lipid composition adjustment to maintain optimal fluidity during water deficit?
Answer: Azospirillum brasilense is able to perceive osmotic changes by changing the membrane fluidity. This effect is offset by changes in the composition of membrane phospholipid and FA, contributing to the homeostasis of membrane fluidity under water deficit.

Ex Output:
yes

Ex Input:
Question: Is exercise training bradycardia largely explained by reduced intrinsic heart rate?
Answer: We did not find evidence that an increase in parasympathetic tone or a decrease in responsiveness to beta-adrenergic activity accounts for the reduction in resting heart rate with exercise training. We suggest that a decline in heart rate with training is most likely due to decrease in the intrinsic heart rate.

Ex Output:
yes
