Question: Passage: Intensity is defined to be the power per unit area carried by a wave. Power is the rate at which energy is transferred by the wave. In equation form, intensity I is. Answer: wave

Answer: Intensity is defined to be the power per unit area carried by a what?

Question: Passage: Telescopes on Earth all have one big problem: incoming light must pass through the atmosphere. This blocks some wavelengths of radiation. Also, motion in the atmosphere distorts light. You see this when you see stars twinkling in the night sky. Many observatories are built on high mountains. There is less air above the telescope, so there is less interference from the atmosphere. Space telescopes avoid problems from the atmosphere completely since they orbit outside the atmosphere. Answer: the atmosphere

Answer: Many observatories are built on high mountains to avoid interference from what?

Question: Passage: When water moves into a cell by osmosis, osmotic pressure may build up inside the cell. If a cell has a cell wall, the wall helps maintain the cell's water balance. Osmotic pressure is the main cause of support in many plants. When a plant cell is in a hypotonic environment, the osmotic entry of water raises the turgor pressure exerted against the cell wall until the pressure prevents more water from coming into the cell. At this point the plant cell is turgid ( Figure below ). The effects of osmotic pressures on plant cells are shown in Figure above . Answer: osmotic pressure

Answer:
What type of pressure may build up inside the cell when water moves into a cell by osmosis?
