Which of the following describes the difference between Carbon−12 and Carbon−14? A. Carbon-12 has 12 electrons, 12 protons, and 12 neutrons; Carbon−14 has 14 electrons, 14 protons, and 14 neutrons. Both are radioactive isotopes. B. Carbon-12 has 6 electrons, 6 protons, and 6 neutrons; Carbon−14 has 6 electrons, 6 protons, and 8 neutrons. Both are radioactive isotopes. C. Carbon−12 has 6 electrons, 6 protons, and 6 neutrons; Carbon−14 has 6 electrons, 6 protons, and 8 neutrons. Only Carbon−14 is a radioactive isotope. D. Carbon−12 has 6 electrons, 6 protons, and 6 neutrons; Carbon−14 has 6 electrons, 6 protons, and 8 neutrons. They are not radioactive isotopes.

Let the ed50 of a recreational drug be defined as the amount required for 50% of a test group to feel high or get a buzz. if the ed50 value of ethanol is 470 mg/kg body mass, what dose would a 70 kg party goer need to quickly consume in order to have a 50% chance of getting a buzz? 235 mg 470 mg 32,900 mg 35,000,000 mg

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
