Answer the following question given this paragraph: The behavior of the atoms, molecules, or ions that comprise the reactants is responsible for the rates of a given chemical reaction. Collision theory is a set of principles that states that the reacting particles can form products when they collide with one another provided those collisions have enough kinetic energy and the correct orientation. Particles that lack the necessary kinetic energy may collide, but the particles will simply bounce off one another unchanged. The figure below illustrates the difference. In the first collision, the particles bounce off one another and no rearrangement of atoms has occurred. The second collision occurs with greater kinetic energy, and so the bond between the two red atoms breaks. One red atom bonds with the other molecule as one product, while the single red atom is the other product. The first collision is called an ineffective collision , while the second collision is called an effective collision . Q: According to collision theory, particles that lack what kind of energy may collide, but the particles will simply bounce off one another unchanged? Choices: - elastic energy - residual energy - viscosity energy - kinetic energy A:
kinetic energy
Answer the following question given this paragraph: Other than insects, virtually no other animals can inhabit the airy world. Flying is a sure-fire way to escape from all but the quickest nonflying predators. Flying also gives birds a good view for finding food and mates. Q: What technique is used by insects and birds to find food, mates, and safety from predators? Choices: - playing - sleeping - mating - flying A:
flying
Q: Answer the following question given this paragraph: Q: When it is winter in the northern hemisphere the southern hemisphere experiences which season? Choices: - winter - autumn - spring - summer A:
A: summer
Question: Answer the following question given this paragraph: Q: What is the shortest phase of the sexual response cycle? Choices: - sexual stimulation - plateau phase - resolution phase - the orgasm A:
Answer: the orgasm

Answer the following question given this paragraph: The parts of the ears involved in balance are the semicircular canals . Above, the semicircular canals are colored purple ( Figure above ). The canals contain liquid and are like the bottle of water pictured below ( Figure below ). When the bottle tips, the water surface moves up and down the sides of the bottle. When the body tips, the liquid in the semicircular canals moves up and down the sides of the canals. Tiny hair cells line the semicircular canals. Movement of the liquid inside the canals causes the hair cells to send nerve impulses. The nerve impulses travel to the cerebellum in the brain along the vestibular nerve. In response, the cerebellum sends commands to muscles to contract or relax so that the body stays balanced. Q: The parts of the ears involved in balance are called what? Choices: - lobe canal - symmetrical canals - rectangular canals - semicircular canals A:
**Answer**
semicircular canals
Q: Answer the following question given this paragraph: Most of the elements we know about do not exist freely in nature. Sodium cannot be found by itself (unless we prepare it in the laboratory) because it interacts easily with other materials. On the other hand, the element helium does not interact with other elements to any extent. We can isolate helium from natural gas during the process of drilling for oil. Q: Sodium is an example of what sort of thing that cannot exist by itself in nature? Choices: - concept - compound - aspect - element A:
A: element
