Answer the following question given this paragraph: The central vacuole contains large amounts of a liquid called cell sap, which differs in composition to the cell cytosol. Cell sap is a mixture of water, enzymes, ions, salts, and other substances. Cell sap may also contain toxic byproducts that have been removed from the cytosol. Toxins in the vacuole may help to protect some plants from being eaten. Q: What is the liquid inside the central vacuole called? Choices: - cytoplasm - osmotic fluid - chloroplasm - cell sap A:
cell sap
Answer the following question given this paragraph: Metals are elements that are good conductors of electricity. They are the largest class of elements. Many metals are shiny, ductile, and malleable. They are also good conductors of heat. Almost all metals are solids are room temperature. Q: What is the largest class of elements? Choices: - organics - acids - oils - metals A:
metals
Q: Answer the following question given this paragraph: Consider a gigantic tub filled with water as shown below. A column of water with a cross-sectional area of 1.00 m 2 is designated. If we multiply the cross-sectional area by the height of the column, we get the volume of water in this column. We can then multiply this volume by the density of water, 1000. kg/m 3 , and get the mass of water in the column. We then multiply this mass by the acceleration due to gravity, , to get the weight of the water in this column. Q: What do you get by multiplying volume by the density of water? Choices: - velocity of water - temperature of water - weight of water - mass of water A:
A: mass of water
Question: Answer the following question given this paragraph: In general, for an electric charge to move from one position to another, there must be a difference in electric potential energy between the two positions. The difference in electric potential energy is called potential difference, or voltage . Voltage is measured in an SI unit called the volt (V). For example, the terminals of the car battery in Figure below have a potential difference of 12 volts. This difference in voltage results in a spontaneous flow of charges, or electric current. Q: The difference in electric potential energy which allows for an electric charge to move from one position to another is measured by what si unit? Choices: - ohm - joule - meter - volt A:
Answer: volt

Answer the following question given this paragraph: During metamorphism, a rock may change chemically. Ions move in or out of a mineral. This creates a different mineral. The new minerals that form during metamorphism are more stable in the new environment. Extreme pressure may lead to physical changes. If pressure is exerted on the rock from one direction, the rock forms layers. This is foliation . If pressure is exerted from all directions, the rock usually does not show foliation. Q: If pressure is exerted on the rock from one direction, the rock forms layers. this is called what? Choices: - protonation - stratification - sedimentation - foliation A:
**Answer**
foliation
Answer the following question given this paragraph: Increasing the temperature increases the average kinetic energy of the N2molecules. Q: Increasing the temperature of n2 molecules increases what energy of motion? Choices: - compression energy - residual energy - emotional energy - kinetic energy A:
kinetic energy
