Q: Which has more electrons, neon or fluorine? Read this paragraph and choose the correct option from the provided answers: Although neon has just one more electron than fluorine in its outer energy level, that one electron makes a huge difference. Fluorine needs one more electron to fill its outer energy level in order to have the most stable arrangement of electrons. Therefore, fluorine readily accepts an electron from any element that is equally "eager" to give one up, such as the metal lithium or sodium. As a result, fluorine is highly reactive. In fact, reactions with fluorine are often explosive, as you can see in the URL below. Neon, on the other hand, already has a full outer energy level. It is already very stable and never reacts with other elements. It neither accepts nor gives up electrons. Neon doesn't even react with fluorine, which reacts with all other elements except helium. Choices: - the same - fluorine - neither - neon A:
(Answer)
neon

Ques:Q: To solubilize the fats so that they can be absorbed, what organ secretes a fluid called bile into the small intestine? Read this paragraph and choose the correct option from the provided answers: A related mechanism allows us to absorb and digest the fats in buttered popcorn and French fries. To solubilize the fats so that they can be absorbed, the gall bladder secretes a fluid called bile into the small intestine. Bile contains a variety of bile salts, detergent-like molecules that emulsify the fats. Choices: - small intestine - stomach - spleen - gall bladder A:

Ans:gall bladder

Question: Q: When cardiac muscle contracts, the heart does what? Read this paragraph and choose the correct option from the provided answers: Cardiac muscle is found only in the walls of the heart. It is striated, or striped, because its muscle fibers are arranged in bundles. Contractions of cardiac muscle are involuntary. This means that they are not under conscious control. When cardiac muscle contracts, the heart beats and pumps blood. Choices: - cardiac arrest - irregular heartbeat - heart murmur - pumps blood A:
Answer:
pumps blood
