Answer the following question given this paragraph: The amount of energy in molecules of matter determines the state of matter . Matter can exist in one of several different states, including a gas, liquid, or solid state. These different states of matter have different properties, which are illustrated in Figure below . Gasses have the most energy, and solids have the least energy. Q: What is determined by the amount of energy in molecules? Choices: - kingdom - radioactivity - momentum - state of matter A:
state of matter
Q: Answer the following question given this paragraph: Once a sand dune forms, it may slowly migrate over the land. The wind moves grains of sand up the gently sloping side of the dune. This is done by saltation. When the sand grains reach the top of the dune, they slip down the steeper side. The grains are pulled by gravity. The constant movement of sand up and over the dune causes the dune to move along the ground. It always moves in the same direction that the wind usually blows. Can you explain why?. Q: The migration of what familiar coastal landform involves saltation and gravity? Choices: - volcanos - lakes - rivers - sand dunes A:
A: sand dunes

Answer the following question given this paragraph: One end of each phospholipid molecule is polar, so it has a partial electric charge. Water is also polar and has electrically charged ends, so it is attracted to the oppositely charged end of a phospholipid molecule. This end of the phospholipid molecule is described as hydrophilic, which means "water loving. ". Q: Water is polar and has electrically charged ends, so it is attracted to the oppositely charged end of a phospholipid molecule, which is described by what term meaning "water-loving"? Choices: - aqueous - hydrophobic - cytosolic - hydrophilic A:
**Answer**
hydrophilic
