Answer the following question given this paragraph: One of the first uses of rockets in space was to launch satellites. A satellite is an object that orbits a larger object. An orbit is a circular or elliptical path around an object. Natural objects in orbit are called natural satellites. The Moon is a natural satellite. Human-made objects in orbit are called artificial satellites. There are more and more artificial satellites orbiting Earth all the time. They all get into space using some sort of rocket. Q: What is an object that orbits a larger object called? Choices: - asteroid - meteorite - comet - satellite A:
satellite
Answer the following question given this paragraph: Q: Lodgepole cones remain closed until exposed to what? Choices: - predators - precipitation - UV light - extreme heat A:
extreme heat
Q: Answer the following question given this paragraph: From the human point of view, natural resources can be classified as renewable or nonrenewable. Q: What are the two classifications of natural resources? Choices: - renewable and reusable - productive and nonrenewable - recyclable and reversible - renewable and nonrenewable A:
A: renewable and nonrenewable
Question: Answer the following question given this paragraph: There are some noticeable spikes on the BE / A graph, which represent particularly tightly bound nuclei. These spikes reveal further details of nuclear forces, such as confirming that closed-shell nuclei (those with magic numbers of protons or neutrons or both) are more tightly bound. The spikes also indicate that some nuclei with even numbers for Z and N , and with Z = N , are exceptionally tightly bound. This finding can be correlated with some of the cosmic abundances of the elements. The most common elements in the universe, as determined by observations of atomic spectra from outer space, are hydrogen, followed by 4 He , with much smaller amounts of 12 C and other elements. It should be noted that the heavier elements are created in supernova explosions, while the lighter ones are produced by nuclear fusion during the normal life cycles of stars, as will be discussed in subsequent chapters. The most common elements have the most tightly bound nuclei. It is also no accident that one of the most tightly bound light nuclei is 4 He , emitted in decay. Q: The most common elements have the most tightly bound __________. Choices: - quarks - membrane - atoms - nuclei A:
Answer: nuclei

Answer the following question given this paragraph: 22.1 Introduction Viruses are the smallest biological particle (the tiniest are only 20 nm in diameter). However, they are not biological organisms so they are not classified in any kingdom of living things. They do not have any organelles and cannot respire or perform metabolic functions. Viruses are merely strands of DNA or RNA surrounded by a protective protein coat called a capsid. Viruses only come to life when they have invaded a cell. Outside of a host cell, viruses are completely inert. Since first being identified in 1935, viruses have been classified into more than 160 major groups. Viruses are classified based on their shape, replication properties, and the diseases that they cause. Furthermore, the shape of a virus is determined by the type and arrangement of proteins in its capsid. Viruses pathogenic to humans are currently classified into 21 groups. Viruses can also attack bacteria and infect bacterial cells. Such viruses are called bacteriophages. Q: The shape of a virus is determined by the type and arrangement of proteins in its what? Choices: - enamel - anode - nuclei - capsid A:
**Answer**
capsid
Q: Answer the following question given this paragraph: Three unit cells of the cubic crystal system. Each sphere represents an atom or an ion. In the simple cubic system, the atoms or ions are at the corners of the unit cell only. In the face-centered unit cell, there are also atoms or ions in the center of each of the six faces of the unit cell. In the body-centered unit cell, there is one atom or ion in the center of the unit cell in addition to the corner atoms or ions. Q: In the simple cubic system, the atoms or ions are located in which part of the cell? Choices: - mitochondria - plasma - walls - corners A:
A: corners
