Which statement correctly explains why a fuel cell is a voltaic cell? it is composed of one oxidation half-reaction. it is composed of one reduction half-reaction. it transfers electrons from oxidation reactions to reduction. it requires either an anode or a cathode but not both. hurry up plzz! thx for ! for 50 points as well!

Effect of rotenone and antimycin a on electron transfer rotenone, a toxic natural product from plants, strongly inhibits nadh dehydrogenase of insect and fish mitochondria. antimycin a, a toxic antibiotic, strongly inhibits the oxidation of ubiquinol. (a) explain why rotenone ingestion is lethal to some insect and fish species. (b) explain why antimycin a is a poison. (c) given that rotenone and antimycin a are equally effective in blocking their respective sites in the electron-transfer chain, which would be a more potent poison? explain.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.

Is this correct if not can u correct me
