Five hundred million years ago, basaltic lava flowed in an area now known as monticello, the historic home of thomas jefferson. some of this rock has since re-crystallized under intense heat and pressure and then has been eroded by wind and rain. the order of the rock cycle in this case is best described as a) metamorphic, igneous, sedimentary. b) igneous, sedimentary, metamorphic. c) igneous, metamorphic, sedimentary. d) metamorphic, sedimentary, igneous.

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.

The identities of substances are the same before and after which type of change

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
