Answer the following question given this paragraph: Perhaps the most familiar example of corrosion is the formation of rust on iron. Iron will rust when it is exposed to oxygen and water. The main steps in the rusting of iron appear to involve the following (Figure 17.17). Once exposed to the atmosphere, iron rapidly oxidizes. anode: Fe(s) Fe 2+(aq) + 2e . Q: Iron will do what when it is exposed to oxygen and water? Choices: - become hot - expand - contract - rust A:
rust
Q: Answer the following question given this paragraph: and procaine. Not only do catalysts greatly increase the rates of reactions, but in some cases such as in petroleum refining, they also control which products are formed. The acceleration of a reaction by a catalyst is called catalysis. Q: Catalysts can greatly increase the rates of chemical what? Choices: - photosynthesis - decay - effects - reactions A:
A: reactions
Question: Answer the following question given this paragraph: Superposition refers to the position of rock layers and their relative ages ( Figure below ). Relative age means age in comparison with other rocks, either younger or older. The relative ages of rocks are important for understanding Earth's history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition. Q: Deeper layers of rock must be older than layers closer to the surface, this is the law of what? Choices: - erosion - diffraction - flux - superposition A:
Answer: superposition

Answer the following question given this paragraph: Today, fungi are no longer classified as plants. We now know that they have unique physical, chemical, and genetic traits that set them apart from plants and other eukaryotes. For example, the cell walls of fungi are made of chitin , not cellulose. Also, fungi absorb nutrients from other organisms, whereas plants make their own food. These are just a few of the reasons fungi are now placed in their own kingdom. Q: Fungi are no longer classified as what, possessing cell walls made of chitin rather than cellulose? Choices: - roots - eukaryotes - flowers - plants A:
(Answer)
plants
