Answer the following question given this paragraph: A seismograph is a machine that records seismic waves. In the past, seismographs produced a seismogram . A seismogram is a paper record of the seismic waves the seismograph received. Seismographs have a weighted pen suspended from a stationary frame. A drum of paper is attached to the ground. As the ground shakes in an earthquake, the pen remains stationary but the drum moves beneath it. This creates the squiggly lines that make up a seismogram ( Figure below ). Q: What is used to record seismic waves? Choices: - transmitter - odometer - topometer - seismograph A:
seismograph

Answer the following question given this paragraph: Many hydrocarbons are cyclic and adopt specific three-dimensional structures that influence their physical and chemical properties. Q: Many hydrocarbons are cyclic and adopt specific three-dimensional structures that influence their physical and what properties? Choices: - liquid - electrical - radiation - chemical A:
(Answer)
chemical

Answer the following question given this paragraph: Sediments are small fragments of rocks and minerals. Pebbles, sand, silt, and clay are examples of sediments. Sedimentary rocks may include fossils. Fossils are materials left behind by once-living organisms. Fossils can be pieces of the organism, like bones. They can also be traces of the organism, like footprints. Q: What is the term for materials that have been left behind by organisms that once lived? Choices: - detritis - skulls - bones - fossils A:
(A).
fossils
Ques:Answer the following question given this paragraph: Geologists study earthquake waves to "see" Earth's interior. Waves of energy radiate out from an earthquake's focus. These are called seismic waves ( Figure below ). Seismic waves change speed as they move through different materials. This causes them to bend. Some seismic waves do not travel through liquids or gases. Scientists use all of this information to understand what makes up the Earth's interior. Q: What type of waves radiate energy out from an earthquake's focus? Choices: - Microwaves - abnormal - volcanic - seismic A:

Ans:seismic
Answer the following question given this paragraph: Inside the plasma membrane of prokaryotic cells is the cytoplasm. It contains several structures, including ribosomes, a cytoskeleton, and genetic material. Ribosomes are sites where proteins are made. The cytoskeleton helps the cell keeps its shape. The genetic material is usually a single loop of DNA. There may also be small, circular pieces of DNA, called plasmids (see Figure below ). The cytoplasm may contain microcompartments as well. These are tiny structures enclosed by proteins. They contain enzymes and are involved in metabolic processes. Q: What is inside the plasma membrane of a prokaryotic cell? Choices: - protoplasm - electron - alkaline - cytoplasm A:
cytoplasm
