Answer the following question given this paragraph: Some life scientists mainly do lab research. Other life scientists, like the botanist in Figure below , work in natural settings. This is called fieldwork . Whether in the lab or the field, research in life science can be dangerous. It's important to be aware of the risks and how to stay safe. Q: When scientists work in natural settings rather than a lab, it is called what? Choices: - outside work - extracurricular activity - exploratory - fieldwork A:
fieldwork
Q: Answer the following question given this paragraph: Most geological activity takes place at plate boundaries. But some activity does not. Much of this intraplate activity is found at hot spots. Hotspot volcanoes form as plumes of hot magma rise from deep in the mantle. Q: Most geological activity takes place where? Choices: - high altitudes - ocean floor - center of plates - at plate boundaries A:
A: at plate boundaries
Question: Answer the following question given this paragraph: Enthalpy changes also occur when a solute undergoes the physical process of dissolving into a solvent. Hot packs and cold packs (see Figure below ) use this property. Many hot packs use calcium chloride, which releases heat when it dissolves according to the equation below. Q: When a solute dissolves into a solvent what is that called? Choices: - solubility - viscosity - mixing - enthalpy A:
Answer: enthalpy
