Answer the following question given this paragraph: Global carbon dioxide emissions from fossil fuel consumption and cement production. The black line represents all emission types combined. The colored lines show emissions from individual fossil fuels. Q: Fossil fuel consumption is a major contributor to global emissions of what gas? Choices: - oxygen - carbon monoxide - methane - carbon dioxide A:
carbon dioxide
Answer the following question given this paragraph: Sugars are simple carbohydrates. Molecules of sugar have just a few carbon atoms. The simplest sugar is glucose (C 6 H 12 O 6 ). Glucose is the sugar that the cells of living things use for energy. Plants and some other organisms make glucose in the process of photosynthesis. Living things that cannot make glucose obtain it by consuming plants or these other organisms. Q: What is the sugar that the cells of living things use for energy? Choices: - insulin - sucrose - chlorophyll - glucose A:
glucose
Q: Answer the following question given this paragraph: The cell cycle is a repeating series of events, characterizing the life of a eukaryotic cell. Q: What does the cell cycle do? Choices: - only divide cells - create new cells - only reproduce cells - divide and reproduce cells A:
A: divide and reproduce cells
Question: Answer the following question given this paragraph: Forces between Molecules Under appropriate conditions, the attractions between all gas molecules will cause them to form liquids or solids. This is due to intermolecular forces, not intramolecular forces. Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Intermolecular forces are the attractions between molecules, which determine many of the physical properties of a substance. Figure 10.5 illustrates these different molecular forces. The strengths of these attractive forces vary widely, though usually the IMFs between small molecules are weak compared to the intramolecular forces that bond atoms together within a molecule. For example, to overcome the IMFs in one mole of liquid HCl and convert it into gaseous HCl requires only about 17 kilojoules. However, to break the covalent bonds between the hydrogen and chlorine atoms in one mole of HCl requires about 25 times more energy430 kilojoules. Q: Under appropriate conditions, the attractions between all molecules in what state will cause them to form liquids or solids? Choices: - soild - plasma - liquid - gas A:
Answer: gas
