Answer the following question given this paragraph: In a chemical reaction, the quantity of each element does not change; there is the same amount of each element in the products as there was in the reactants. This is because matter is always conserved. The conservation of matter is reflected in a reaction's chemical equation. The same number of atoms of each element appears on each side of the arrow. For example, in the chemical equation above, there are four hydrogen atoms on each side of the arrow. Can you find all four of them on each side of this equation?. Q: Matter is always conserved in what type of reaction? Choices: - developed reaction - Quick reaction - toxic reaction - chemical reaction A:
chemical reaction
Answer the following question given this paragraph: the bottom of the cell. In roots, a high concentration of IAA inhibits cell elongation. The effect slows growth on the lower side of the root, while cells develop normally on the upper side. IAA has the opposite effect in shoots, where a higher concentration at the lower side of the shoot stimulates cell expansion, causing the shoot to grow up. After the shoot or root begin to grow vertically, the amyloplasts return to their normal position. Other hypothesesinvolving the entire cell in the gravitropism effecthave been proposed to explain why some mutants that lack amyloplasts may still exhibit a weak gravitropic response. Q: In plants, a high concentration of iaa inhibits what? Choices: - Cell reproduction - same elongation - technology elongation - cell elongation A:
cell elongation
Q: Answer the following question given this paragraph: Complexing agents that tie up metal ions are also used as drugs. British Anti-Lewisite (BAL), HSCH2CH(SH)CH2OH, is a drug developed during World War I as an antidote for the arsenic-based war gas Lewisite. BAL is now used to treat poisoning by heavy metals, such as arsenic, mercury, thallium, and chromium. The drug is a ligand and functions by making a water-soluble chelate of the metal; the kidneys eliminate this metal chelate (Figure 19.31). Another polydentate ligand, enterobactin, which is isolated from certain bacteria, is used to form complexes of iron and thereby to control the severe iron buildup found in patients suffering from blood diseases such as Cooley's anemia, who require frequent transfusions. As the transfused blood breaks down, the usual metabolic processes that remove iron are overloaded, and excess iron can build up to fatal levels. Enterobactin forms a watersoluble complex with excess iron, and the body can safely eliminate this complex. Q: How does consuming enterobactin help our body? Choices: - builds excess iron - eliminates excess fat - eliminates excess oxygen - eliminates excess iron A:
A: eliminates excess iron
Question: Answer the following question given this paragraph: A refrigerator is an example of a cooling system. Another example is an air conditioner. The purpose of any cooling system is to transfer thermal energy in order to keep things cool. A refrigerator, for example, transfers thermal energy from the cool air inside the refrigerator to the warm air in the kitchen. If you've ever noticed how warm the back of a running refrigerator gets, then you know that it releases a lot of thermal energy into the room. Q: The purpose of any cooling system is to transfer what type of energy in order to keep things cool? Choices: - radiation - atmospheric - physical - thermal A:
Answer: thermal

Answer the following question given this paragraph: Acidophiles are organisms that "love" acids. They live in very acidic environments, such as acid mine drainage. They are also found near vents of volcanoes. The most acidophilic archaeans can thrive at negative pH values. No other organisms can survive in such acidic conditions. Q: Organisms that "love" acids are known as what? Choices: - acidophobes - acidic - acid heads - acidophiles A:
**Answer**
acidophiles
Q: Answer the following question given this paragraph: If the rocks on one or both sides of a fracture move, the fracture is called a fault ( Figure below ). Faults can occur alone or in clusters, creating a fault zone . Earthquakes happen when rocks break and move suddenly. The energy released causes an earthquake. Q: What is it called when multiple faults are located in close proximity to one another? Choices: - fog zone - crystal zone - solid zone - fault zone A:
A: fault zone
