Answer the following question given this paragraph: To prepare coal for use, the coal is first crushed into powder and burned in a furnace. Like other fuels, coal releases most of its energy as heat when it burns. The heat from the burning coal is used to boil water. This makes steam. The steam spins turbines, which creates electricity. Q: When does coal release most of its energy? Choices: - when forming - when compressed - when falling - when burning A:
when burning

Answer the following question given this paragraph: A: Humidity is a measure of the amount of water vapor in the air. When humidity is high, sweat evaporates more slowly because there is already a lot of water vapor in the air. The slower evaporation rate reduces the potential for evaporative cooling. Q: What is the measurement for the amount of water vapor in the air? Choices: - haze - ambient - saturation - humidity A:
(Answer)
humidity

Answer the following question given this paragraph: Cell Structure The cells of protists are among the most elaborate of all cells. Most protists are microscopic and unicellular, but some true multicellular forms exist. A few protists live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism. Still other protists are composed of enormous, multinucleate, single cells that look like amorphous blobs of slime, or in other cases, like ferns. In fact, many protist cells are multinucleated; in some species, the nuclei are different sizes and have distinct roles in protist cell function. Single protist cells range in size from less than a micrometer to three meters in length to hectares. Protist cells may be enveloped by animal-like cell membranes or plant-like cell walls. Others are encased in glassy silica-based shells or wound with pellicles of interlocking protein strips. The pellicle functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion. Q: What functions like a flexible coat of armor, preventing the protist from being torn or pierced without compromising its range of motion? Choices: - fimbriae - biofilm - endothelium - pellicle A:
pellicle
