Q: 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:
A: percent yield

Q: Answer the following question given this paragraph: One seismogram indicates the distance to the epicenter. This is determined by the P-and S-wave arrival times. If a quake is near the seismograph, the S-waves arrive shortly after the P-waves. If a quake is far from the seismograph, the P-waves arrive long before the S-waves. The longer the time is between the P-and S-wave arrivals, the further away the earthquake was from the seismograph. First, seismologists calculate the arrival time difference. Then they know the distance to the epicenter from that seismograph. Q: One seismogram indicates the distance to the what? Choices: - researchers - houses - the moon - epicenter A:
A: epicenter

Q: Answer the following question given this paragraph: Both flukes and tapeworms are parasites with vertebrate hosts, including human hosts. Flukes live in the host's circulatory system or liver. Tapeworms live in the host's digestive system. Usually, more than one type of host is required to complete the parasite's life cycle. Look at the life cycle of the liver fluke in Figure below . As an adult, the fluke has a vertebrate host. As a larva, it has an invertebrate host. If you follow the life cycle, you can see how each host becomes infected so the fluke can continue its life cycle. Q: Both flukes and tapeworms are parasites with what kind of host? Choices: - insect - trees - cells - vertebrate A:
A: vertebrate
