Answer the following question given this paragraph: (a) Two solutions of differing concentrations are placed on either side of a semipermeable membrane. (b) When osmosis occurs, solvent molecules selectively pass through the membrane from the dilute solution to the concentrated solution, diluting it until the two concentrations are the same. The pressure exerted by the different height of the solution on the right is called the osmotic pressure. The osmotic pressure of a solution is easy to calculate:. Q: When solvent molecules selectively pass through a membrane from a dilute solution to concentrated solution, what process is occurring? Choices: - plasmolysis - active transport - diffusion - osmosis A:
osmosis

Answer the following question given this paragraph: In science, a theory has been repeatedly shown to be true. A theory is supported by many observations. However, a theory may be disproved if conflicting data is discovered. Many important theories have been shown to be true by many observations and experiments and are extremely unlikely to be disproved. These include the theory of plate tectonics and the theory of evolution. Q: What does a theory need to be supported by? Choices: - facts - peer reviewed journals - scientists - many observations A:
(Answer)
many observations
Ques: Answer the following question given this paragraph: Most amphibians live in fresh water, not salt water. Their habitats can include areas close to springs, streams, rivers, lakes, swamps and ponds. They can be found in moist areas in forests, meadows and marshes. Amphibians can be found almost anywhere there is a source of fresh water. Although there are no true saltwater amphibians, a few can live in brackish (slightly salty) water. Some species do not need any water at all, and several species have also adapted to live in drier environments. Most amphibians still need water to lay their eggs. Q: Where do most amphibians live, salt water or fresh water? Choices: - aquariums - deserts - saltwater - fresh water A:
Ans: fresh water
(Q).
Answer the following question given this paragraph: Only a tiny fraction of Earth's freshwater is in the liquid state. Most liquid freshwater is under the ground in layers of rock. Of freshwater on the surface, the majority occurs in lakes and soil. What percentage of freshwater on the surface is found in living things?. Q: Most liquid freshwater is under the ground in layers of what? Choices: - forest - sand - soil - rock A:
(A).
rock
Ques:Answer the following question given this paragraph: Recall from the kinetic-molecular theory that gas particles move randomly and in straight lines until they elastically collide with either other gas particles or with one of the walls of the container. It is these collisions with the walls of the container that defines the pressure of the gas. Four variables are used to describe the condition of a gas. They are pressure , volume , temperature , and the amount of the gas as measured by the number moles . We will examine separately how the volume, temperature, and amount of gas each affect the pressure of an enclosed gas sample. Q: How many variables are used to describe the condition of a gas? Choices: - five - one - three - four A:

Ans:four
Answer the following question given this paragraph: Q: What is the process that breaks down rocks into smaller pieces? Choices: - erosion - bracing - bleaching - weathering A:
weathering
