Answer the following question given this paragraph: Metalloids such as boron have an outer energy level that is about half full. These elements need to gain or lose too many electrons for a full outer energy level to come about easily. As a result, these elements are not very reactive. They may be able to conduct electricity but not very well. Q: About how full is the outer energy level in metalloids? A:
****
A: half full

Answer the following question given this paragraph: Q: Both endotherms and ectotherms control what through behavioral responses to changes in the environment? A:
OPTIONS:
- sleep cycles
- hormones
- gas temperature
- body temperature
body temperature

Answer the following question given this paragraph: Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of 11 H, neutrons. Recall that the number of protons in the nucleus is called the atomic number (Z) of the element, and the sum of the number of protons and the number of neutrons is the mass number (A). Atoms with the same atomic number but different mass numbers are isotopes of the same element. When referring to a single type of nucleus, we often use the term nuclide and identify it by the notation A where X is the symbol Z X, 14 Often a nuclide is referenced 6 C. example, 146 C is called "carbon-14. Q: Atoms with the same atomic number but different mass numbers are called what? A:
OPTIONS:
- tropes
- organisms
- reactions
- isotopes

Answer: isotopes

Question: Answer the following question given this paragraph: Look at the scissors in Figure below . As you can see from the figure, scissors consist of two levers and two wedges. You apply force to the handle ends of the levers, and the output force is exerted by the blade ends of the levers. The fulcrum of both levers is where they are joined together. Notice that the fulcrum lies between the input and output points, so the levers are first-class levers. They change the direction of force. They may or may not also increase force, depending on the relative lengths of the handles and blades. The blades themselves are wedges, with a sharp cutting edge and a thicker dull edge. Q: Are scissors simple or compound machines? A:
OPTIONS:
- lever
- neither
- simple
- compound
Answer: compound

Small amounts of iodine are also needed for good health. In the U. S. , iodine is added to table salt to prevent iodine deficiencies. Does the salt you use contain iodine?. Q: What is added to alcohol and used as an antiseptic? A:
OPTIONS:
- chloride
- arsenic
- chlorine
- iodine
output: iodine

Problem: OPTIONS:
- arthritis
- headache
- sunburn
- heartburn
Q: Answer the following question given this paragraph: Have you ever experienced heartburn? Heartburn is actually a condition caused by stomach acid, rather something in your heart. The stomach produces HCl, which is a necessary component of digestion. However, excessive amounts of stomach acid can cause a great deal of discomfort. Various factors can cause the overproduction of acid, mostly related to the types (and amounts) of food and beverages that are being consumed. Caffeine and other oils in coffee (even decaf) will increase HCl production in the stomach. Smoking cigarettes and drinking alcohol also increase the formation of stomach acid. Q: What is a common condition caused by stomach acid? A:
Answer:
heartburn
