Answer the following question given this paragraph: Chemical reactions in the real world don't always go exactly as planned on paper. In the course of an experiment, many things will contribute to the formation of less product than would be predicted. Besides spills and other experimental errors, there are usually losses due to an incomplete reaction, undesirable side reactions, etc. Chemists need a measurement that indicates how successful a reaction has been. This measurement is called the percent yield. Q: What is the term for proportion of amount of product actually produced in a chemical reaction versus predicted amount ? Choices: - calculus yield - decrease yield - percent impact - percent yield A:
percent yield

Answer the following question given this paragraph: Evolution means change over time. Darwin's theory of evolution says that organisms change over time ( Figure below ). Evolution is seen in the fossil record. It is seen in the way organisms develop. Evolution is evident in the geographic locations where organism are found. It is evident in the genes of living organisms. Evolution has a mechanism called natural selection . The organism that is best suited to its environment is most likely to survive. Evolution is described in the chapter Life on Earth . Q: Organism's changing over time is called? Choices: - generation - heterogenicity - variation - evolution A:
evolution
