Q: What is the common name of mixtures of hydrocarbons that formed over millions of years from the remains of dead organisms? Read this paragraph and choose the correct option from the provided answers: Fossil fuels are mixtures of hydrocarbons that formed over millions of years from the remains of dead organisms. They include petroleum (commonly called oil), natural gas, and coal. Fossil fuels provide most of the energy used in the world today. They are burned in power plants to produce electrical energy, and they also fuel cars, heat homes, and supply energy for many other purposes. You can see examples of their use in Figure below . Choices: - fossil record - renewable resources - non-renewable fuel - fossil fuels A:
fossil fuels

Q: What influences the types of plants and animals that inhabit a specific biome? Read this paragraph and choose the correct option from the provided answers: Climate influences the types of plants and animals that inhabit a specific biome. Choices: - carbon - Water - cooling - climate A:
climate

Q: Q: Virtually every task performed by living organisms requires this? Read this paragraph and choose the correct option from the provided answers: Introduction Virtually every task performed by living organisms requires energy. Energy is needed to perform heavy labor and exercise, but humans also use energy while thinking, and even during sleep. In fact, the living cells of every organism constantly use energy. Nutrients and other molecules are imported into the cell, metabolized (broken down) and possibly synthesized into new molecules, modified if needed, transported around the cell, and possibly distributed to the entire organism. For example, the large proteins that make up muscles are built from smaller molecules imported from dietary amino acids. Complex carbohydrates are broken down into simple sugars that the cell uses for energy. Just as energy is required to both build and demolish a building, energy is required for the synthesis and breakdown of molecules as well as the transport of molecules into and out of cells. In addition, processes such as ingesting and breaking down pathogenic bacteria and viruses, exporting wastes and toxins, and movement of the cell require energy. From where, and in what form, does this energy come? How do living cells obtain energy, and how do they use it? This chapter will discuss different forms of energy and the physical laws that govern energy transfer. This chapter will also describe how cells use energy and replenish it, and how chemical reactions in the cell are performed with great efficiency. Choices: - solids - mineral - metals - energy A:
A: energy

Question: Q: How many times does the height of the largest wave increase with each level? Read this paragraph and choose the correct option from the provided answers: Richter scale magnitudes jump from one level to the next. The height of the largest wave increases 10 times with each level. So the height of the largest seismic wave of a magnitude 5 quake is 10 times that of a magnitude 4 quake. A magnitude 5 is 100 times that of a magnitude 3 quake. With each level, thirty times more energy is released. A difference of two levels on the Richter scale equals 900 times more released energy. Choices: - 20 times - 100 times - 5 times - 10 times A:
Answer: 10 times
