Answer the following question given this paragraph: A person can live a normal, healthy life with just one kidney. However, at least one kidney must function properly to maintain life. Diseases that threaten the health and functioning of the kidneys include kidney stones, infections, and diabetes. Q: Stones, infections, and diabetes threaten the health and functioning of what paired organs? Choices: - tissues - lungs - arteries - kidneys A:
kidneys
Answer the following question given this paragraph: Q: When a plant has what deficiency, guard cells may lose turgor and close stomata? Choices: - cold - light - air - water A:
water
Q: Answer the following question given this paragraph: Radioactivity involves the release of particles and/or energy from the nucleus of an atom. Q: What is the release of particles and/or energy from the nucleus of an atom described as? Choices: - kinetic energy - momentum - temperature - radioactivity A:
A: radioactivity
Question: Answer the following question given this paragraph: The same principles govern the solubilities of molecular solids in liquids. For example, elemental sulfur is a solid consisting of cyclic S8 molecules that have no dipole moment. Because the S8 rings in solid sulfur are held to other rings by London dispersion forces, elemental sulfur is insoluble in water. It is, however, soluble in nonpolar solvents that have comparable London dispersion forces, such as CS2 (23 g/100 mL). In contrast, glucose contains five OH groups that can form hydrogen bonds. Consequently, glucose is very soluble in water (91 g/120 mL of water) but essentially insoluble in nonpolar solvents such as benzene. The structure of one isomer of glucose is shown here. Q: What type of solvents is glucose insoluble in? Choices: - alkaline - polar - acidic - nonpolar A:
Answer: nonpolar

Answer the following question given this paragraph: Ocean water is most polluted along coasts. That's because pollution usually enters the water from land. Oil spills also pollute ocean water. Q: Where would you find most pollution of ocean water? Choices: - midocean - poles - trenches - coastline A:
**Answer**
coastline
Answer the following question given this paragraph: The Arrhenius definition of acids and bases is somewhat limited. There are some compounds whose properties suggest that they are either acidic or basic, but which do not qualify according to the Arrhenius definition. An example is ammonia (NH 3 ). Its aqueous solution turns litmus blue, it reacts with acids, and displays all the other properties of a base. However, it does not contain the hydroxide ion. In 1923, a broader definition of acids and bases was independently proposed by Danish chemist Johannes Brnsted (1879-1947) and English chemist Thomas Lowry (1874-1936). A Brnsted-Lowry acid is a molecule or ion that donates a hydrogen ion in a reaction. A Brnsted-Lowry base is a molecule or ion that accepts a hydrogen ion in a reaction. A hydrogen ion is commonly referred to as a proton, and so acids and bases are proton donors and proton acceptors respectively according to the Brnsted-Lowry definition. All substances that are categorized as acids and bases under the Arrhenius definition are also defined as such under the Brnsted-Lowry definition. The new definition, however, includes some substances that are left out according to the Arrhenius definition. Q: Which type of substance is considered a proton donor in a reaction? Choices: - base - carbon - oxygen - acid A:
acid
