Answer the following question given this paragraph: Q: What are the layered rocks that form when certain prokaryotes bind thin films of sediment together? Choices: - stalagmites - quartzes - stalactites - stomatolites A:
stomatolites

Answer the following question given this paragraph: In normal faults , the hanging wall drops down relative to the footwall. Normal faults are caused by tension that pulls the crust apart. This causes the hanging wall to slide down. Normal faults can build huge mountain ranges in regions experiencing tension ( Figure below ). Q: What makes up most of the inside of a plant? Choices: - star tissue - animal tissue - mitochondria - ground tissue A:
ground tissue

Answer the following question given this paragraph: A balanced chemical equation provides a great deal of information in a very succinct format. Chemical formulas provide the identities of the reactants and products involved in the chemical change, allowing classification of the reaction. Coefficients provide the relative numbers of these chemical species, allowing a quantitative assessment of the relationships between the amounts of substances consumed and produced by the reaction. These quantitative relationships are known as the reaction's stoichiometry, a term derived from the Greek words stoicheion (meaning "element") and metron (meaning "measure"). In this module, the use of balanced chemical equations for various stoichiometric applications is explored. The general approach to using stoichiometric relationships is similar in concept to the way people go about many common activities. Food preparation, for example, offers an appropriate comparison. A recipe for making eight pancakes calls for 1 cup pancake mix, 3 cup milk, and one egg. The "equation" representing the preparation of 4 pancakes per this recipe is 1 cup mix + 3 cup milk + 1 egg 8 pancakes 4 If two dozen pancakes are needed for a big family breakfast, the ingredient amounts must be increased proportionally according to the amounts given in the recipe. For example, the number of eggs required to make 24 pancakes is 24 pancakes . Q: What provides the identities of the reactants and products involved in the chemical change? Choices: - electron shells - genome sequence - atomic numbers - chemical formulas A:
chemical formulas

Answer the following question given this paragraph: An enzyme is an organic catalyst produced by a living cell. Enzymes are such powerful catalysts that the reactions they promote occur rapidly at body temperature. Without the help of enzymes, these reactions would require high temperatures and long reaction times. The molecule or molecules on which an enzyme acts are called its substrates. An enzyme has an active site where its substrate or substrates bind to form an enzymesubstrate complex. The reaction occurs, and product is released:. Q: An enzyme is an organic catalyst produced by what? Choices: - DNA - the liver - amino acid - living cell A:
living cell
