Answer the following question given this paragraph: The goal of technology is to solve people's problems. Therefore, the problems of society generally set the direction that technology takes. Technology, in turn, affects society. It may make people's lives easier or healthier. Two examples are described in Figure below . Q: What generally sets the direction that technology takes? Choices: - local animals - local weather - random chance - problems of society A:
problems of society
Answer the following question given this paragraph: Metals are elements that are good conductors of electricity. They are the largest class of elements. Many metals are shiny, ductile, and malleable. They are also good conductors of heat. Almost all metals are solids are room temperature. Q: What is the largest class of elements? Choices: - organics - acids - oils - metals A:
metals
Q: Answer the following question given this paragraph: To the extent that behaviors are controlled by genes, they may evolve through natural selection. If behaviors increase fitness , they are likely to become more common over time. If they decrease fitness, they are likely to become less common. Q: To the extent that behaviors are controlled by what, they may evolve through natural selection? Choices: - rna - dna - mutation - genes A:
A: genes
Question: Answer the following question given this paragraph: There are many examples in the chemical world of changes in entropy. Phase transitions are one obvious example. When a substance makes a transition from the liquid state to the gaseous state, the particles have many more possible arrangements, because they are no longer confined to a specified volume in which they are close to each other; gas particles can move freely throughout their container. Vaporization represents an increase in entropy. In the opposite direction, a liquid loses entropy when it freezes to a solid. Because solids have very ordered structures, there are fewer possible arrangements of particles that would result in the properties associated with a solid. Q: The phase transition of a substance changing from a liquid state to a gaseous state is an example of what? Choices: - trichina - spirogyra - catostrophy - entropoy A:
Answer: entropoy

Answer the following question given this paragraph: Modern plants that live in water are called aquatic plants . Living in water has certain advantages for plants. One advantage is, well, the water. There's plenty of it and it's all around. Therefore, most aquatic plants do not need adaptations for absorbing, transporting, and conserving water. They can save energy and matter by not growing extensive root systems, vascular tissues, or thick cuticle on leaves. Support is also less of a problem because of the buoyancy of water. As a result, adaptations such as strong woody stems and deep anchoring roots are not necessary for most aquatic plants. Q: What type of plants do not typically require deep roots or woody stems? Choices: - surface plants - dry plants - bacterial plants - aquatic plants A:
**Answer**
aquatic plants
Q: Answer the following question given this paragraph: Pure substances, such as compounds, can be separated through chemical changes. Chemical changes change the chemical composition of a substance and can only occur through a chemical reaction. Q: What changes the chemical composition of a substance and can only occur through a chemical reaction? Choices: - carbon changes - Oxygen Changes - mineral changes - chemical changes A:
A: chemical changes
