Why does Uranus have a higher velocity at perihelion (closest to the Sun) than at aphelion (farthest from the Sun) *
1 point
less gravitational attraction from the Sun
more gravitational attraction from the Sun
more inertia from its long period of rotation
because of its 90-degree obliquity

Check the correct box to describe the periodic trends in electronegativity. electronegativity across a period: decreases. increases. electronegativity down a group: decreases. increases.

How do scientists think that gravity affected the formation of our solar system?

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.
