Answer the following question given this paragraph: In eukaryotic cells, the nucleus divides before the cell itself divides. The process in which the nucleus divides is called mitosis. Before mitosis occurs, a cell's DNA is replicated. This is necessary so that each daughter cell will have a complete copy of the genetic material from the parent cell. How is the replicated DNA sorted and separated so that each daughter cell gets a complete set of the genetic material? To understand how this happens, you need to know more chromosomes. Q: The process in which the nucleus divides is called what? Choices: - meiosis - epistasis - cytokinesis - mitosis A:
mitosis

Answer the following question given this paragraph: Continental glaciers form in a central location with ice moving outward in all directions. Alpine glaciers form in high mountains and travel through valleys. Ice caps cover large areas. Q: Which type of glaciers form in high mountains and travel through valleys? Choices: - rocky glaciers - altitude glaciers - seaside glaciers - alpine glaciers A:
alpine glaciers

Answer the following question given this paragraph: Food Chains. These two food chains represent complex systems in nature. They make the systems easier to understand. These are simple conceptual models. Models of very complex systems are often based on mathematical equations or computer simulations. Q: What kind of tool, often based on mathematical equations or computer simulations, helps us understand complex systems? Choices: - levels - planes - panels - models A:
models
