Gravity pulled materials together forming the planets in our solar system. The inner planets consist of dense material, such as iron, which was pulled to the center of the planets. Materials such as ice, liquid and gas formed the outer planets. Scientist identify this process as: Question 1 options:

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.
