Problem: OPTIONS:
- freezes or boils
- disappears
- rises or vaporizes
- expands or contracts
Q: Answer the following question given this paragraph: Many thermometers measure temperature with a liquid that expands when it gets warmer and contracts when it gets cooler. Look at the common household thermometer pictured in the Figure below . The red liquid rises or falls in the glass tube as the temperature changes. Temperature is read off the scale at the height of the liquid in the tube. To learn more about measuring temperature, watch the animation "Measuring Temperature" at this URL: http://www. sciencehelpdesk. com/unit/science2/3. Q: How does the liquid in a thermometer respond to heat or cold? A:
Answer: expands or contracts

Problem:OPTIONS:
- oxid reactions
- morph reactions
- reflex reactions
- redox reactions

Answer the following question given this paragraph: In stoichiometry, quantities of reactants and/or products can be related to each other using the balanced chemical equation. The coefficients in a balanced chemical reaction are used to devise the proper ratios that relate the number of molecules of one substance to the number of molecules of another substance. Chemical reactions can be classified by type. Combination reactions (also called composition reactions) make a substance from other substances. Decomposition reactions break one substance down into multiple substances. Combustion reactions combine molecular oxygen with the atoms of another reactant. Oxidation reactions are reactions in which an atom loses an electron. Reduction reactions are reactions in which an atom gains an electron. These two processes always occur together, so they are collectively referred to as oxidationreduction (or redox) reactions. The species being oxidized it called the reducing agent, while the species being reduced is the oxidizing agent. Alternate definitions of oxidation and reduction focus on the gain or loss of oxygen atoms, or the loss or gain of hydrogen atoms. Redox reactions are easily balanced if the overall reaction is first separated into half reactions, which are individually balanced. Oxidation-reduction reactions are common in organic and biological chemistry. Respiration, the process by which we inhale and metabolize oxygen, is a series of redox reactions. In the absence of oxygen, redox reactions still occur in a process called anaerobic metabolism. Antioxidants such as ascorbic acid also play a part in the human diet, acting as reducing agents in various biochemical reactions. Photosynthesis, the process by which plants convert water and carbon dioxide to glucose, is also based on redox reactions. Q: What abbreviated form refers to oxidation-reduction reactions, which are part of respiration and photosynthesis? A:
****
A: redox reactions

Answer the following question given this paragraph: Angiosperms , or flowering seed plants, form seeds in ovaries. As the seeds develop, the ovaries may develop into fruits. Flowers attract pollinators, and fruits encourage animals to disperse the seeds. Q: What is the term for flowering seed plants? A:
OPTIONS:
- spores
- perennials
- gymnosperms
- angiosperms
angiosperms

Answer the following question given this paragraph: The vertebrate endoskeleton is made of bone and cartilage. Cartilage is a tough, flexible tissue that contains a protein called collagen. Bone is a hard tissue consisting of a collagen framework that is filled in with minerals such as calcium. Bone is less flexible than cartilage but stronger. A bony endoskeleton allows an animal to grow larger and heavier than a cartilage endoskeleton would. Bone also provides more protection for soft tissues and internal organs. Q: The vertebrate endoskeleton is made of bone and what tough, flexible tissue? A:
OPTIONS:
- cuticle
- collagen
- synovial tissue
- cartilage

Answer: cartilage

Question: Answer the following question given this paragraph: The vertebral column is the core of the vertebrate endoskeleton, or internal skeleton. You can see a human skeleton as an example of the vertebrate endoskeleton in Figure below . In addition to the vertebral column, the vertebrate endoskeleton includes:. Q: The vertebrate endoskeleton can also be called what? A:
OPTIONS:
- structural skeleton
- exoskeleton
- deep skeleton
- internal skeleton
Answer: internal skeleton

input: OPTIONS:
- solar
- humidity
- temperature
- heat Now, answer this question: Answer the following question given this paragraph: Q: What is another word for thermal energy? A:
