54 points the solubility of sodium chloride is 35.9 g/100 g h2o at 20°c. 35.9 g of sodium chloride are added to 100 g of water, and all of it dissolves. another solution is made from the same amount of salt and the same amount of water. this time some solid remains undissolved. what factor could cause the difference? volume temperature beaker size solute purity

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.
