Q: If everything else stays the same in a system with a gas in it, and the gas gets warmer, what will happen to its pressure, generally? Read this paragraph and choose the correct option from the provided answers: Why does the pressure of a gas increase as it gets warmer? Particles of a gas are constantly moving and bumping into things. The force of the collisions is measured by pressure. Pressure is the amount of force exerted on a given area, such as pounds of force per square inch. When gas particles heat up and gain energy, they move faster. This causes more collisions and greater pressure. Therefore, heating particles of gas in a closed space causes the pressure of the gas to increase. Explore the behavior of gas particles at different temperatures at the following URL. Change the temperature of the gas and watch what happens to its particles. Choices: - it drops - it stays the same - it's eliminated - it increases A:
it increases

Ques: Q: Whether the organism is a bacterium, plant, or animal, all living things access energy by breaking down these? Read this paragraph and choose the correct option from the provided answers: The Energy Cycle Whether the organism is a bacterium, plant, or animal, all living things access energy by breaking down carbohydrate molecules. But if plants make carbohydrate molecules, why would they need to break them down, especially when it has been shown that the gas organisms release as a "waste product" (CO2) acts as a substrate for the formation of more food in photosynthesis? Remember, living things need energy to perform life functions. In addition, an organism can either make its own food or eat another organismeither way, the food still needs to be broken down. Finally, in the process of breaking down food, called cellular respiration, heterotrophs release needed energy and produce "waste" in the form of CO2 gas. In nature, there is no such thing as waste. Every single atom of matter and energy is conserved, recycling over and over infinitely. Substances change form or move from one type of molecule to another, but their constituent atoms never disappear (Figure 8.20). CO2 is no more a form of waste than oxygen is wasteful to photosynthesis. Both are byproducts of reactions that move on to other reactions. Photosynthesis absorbs light energy to build carbohydrates in chloroplasts, and aerobic cellular respiration releases energy by using oxygen to metabolize carbohydrates in the cytoplasm and mitochondria. Both processes use electron transport chains to capture the energy necessary to drive other reactions. These two powerhouse processes, photosynthesis and cellular respiration, function in biological, cyclical harmony to allow organisms to access life-sustaining energy that originates millions of miles away in a burning star humans call the sun. Choices: - lipid molecules - protein molecules - oxygen molecules - carbohydrate molecules A:
Ans: carbohydrate molecules

Q: Water leaves ponds and lakes through evaporation and also as what? Read this paragraph and choose the correct option from the provided answers: Ponds and lakes may get their water from several sources. Some falls directly into them as precipitation. Some enters as runoff and some from streams and rivers. Water leaves ponds and lakes through evaporation and also as outflow. Choices: - inflow - influx - mid flow - outflow A:
(A).
outflow

Ques:Q: Heat, electricity, or light might provide what necessary input to the process of decomposition? Read this paragraph and choose the correct option from the provided answers: Most decomposition reactions require an input of energy in the form of heat, light, or electricity. Choices: - source - material - food - energy A:

Ans:energy

Q: Do waves move faster when particles are close to each other or far away? Read this paragraph and choose the correct option from the provided answers: The speed of most waves depends on the medium through which they are traveling. Generally, waves travel fastest through solids and slowest through gases. That's because particles are closest together in solids and farthest apart in gases. When particles are farther apart, it takes longer for the energy of the disturbance to pass from particle to particle. Choices: - unaffected - far away - open - close A:
close
