reactants → products
Based on the Law of Conservation of Matter, describe the relationship between the mass of the reactants and the mass of the products.

Embryos of different species look very similar, which shows that the organisms share a ancestor.

Summarize possible ways in which phases of matter could combine to form a solution.

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.
