instruction:
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.
question:
Question: Are fatty acid-amino acid conjugates essential for systemic activation of salicylic acid-induced protein kinase and accumulation of jasmonic acid in Nicotiana attenuata?
Answer: Our results reveal that N. attenuata specifically recognizes herbivore-derived FACs in damaged leaves and rapidly send out a long-distance signal to phylotactically connected leaves to activate MAPK and JA signaling, and we propose that FACs that penetrated into wounds rapidly induce the production of another long-distance signal(s) which travels to all systemic leaves and activates TPI defense.
answer:
yes


question:
Question: Is increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines associated with risk of autism?
Answer: In this study of MCO members, increasing exposure to antibody-stimulating proteins and polysaccharides in vaccines during the first 2 years of life was not related to the risk of developing an ASD.
answer:
no


question:
Question: Does an increased circulating blood volume prevent hypotension after pheochromocytoma resection?
Answer: Expansion of the CBV by alpha-blocker therapy was related to lower blood pressures after resection of the pheochromocytoma. Expansion of the CBV by an alpha blocker may have increased the elastance of blood vessels. Preoperative blood volume expansion does not preclude hypotension after tumour resection. Although the CBV value itself is not a predictor for hypotension after tumour resection, pulse dye-densitometry provides values of CO and CBV simultaneously, assisting in the management of volume resuscitation and/or the need for catecholamines.
answer:

no
