Answer the following question given this paragraph: The rate of evaporation depends only on the surface area of the liquid and is essentially constant. The rate of condensation depends on the number of molecules in the vapor phase and increases steadily until it equals the rate of evaporation. Q: The rate of evaporation depends only on the surface area of the liquid and is essentially constant. the rate of condensation depends on the number of molecules in the vapor phase and increases steadily until it equals the rate of this? Choices: - accumulation - condensation - absorption - evaporation A:
evaporation

Answer the following question given this paragraph: Figure 3.26 The beta chain of hemoglobin is 147 residues in length, yet a single amino acid substitution leads to sickle cell anemia. In normal hemoglobin, the amino acid at position seven is glutamate. In sickle cell hemoglobin, this glutamate is replaced by a valine. Q: A single amino acid substitution in hemoglobin leads to what disease? Choices: - crohn's disease - AIDS - down's syndrome - sickle cell anemia A:
(Answer)
sickle cell anemia
Ques: Answer the following question given this paragraph: A superheated liquid exists temporarily as liquid with a temperature above the normal boiling point of the liquid. When a supercooled liquid boils, the temperature drops as the liquid is converted to vapor. Conversely, a supercooled liquid exists temporarily as a liquid with a temperature lower than the normal melting point of the solid. As shown below, when a supercooled liquid crystallizes, the temperature increases as the liquid is converted to a solid. Q: When a supercooled liquid boils, the temperature drops as the liquid is converted to what? Choices: - carbon - solid - atoms - vapor A:
Ans: vapor

an allergen
Ques:Answer the following question given this paragraph: 4.4 Newton's Third Law of Motion: Symmetry in Forces There is a passage in the musical Man of la Mancha that relates to Newton's third law of motion. Sancho, in describing a fight with his wife to Don Quixote, says, "Of course I hit her back, Your Grace, but she's a lot harder than me and you know what they say, 'Whether the stone hits the pitcher or the pitcher hits the stone, it's going to be bad for the pitcher. '" This is exactly what happens whenever one body exerts a force on anotherthe first also experiences a force (equal in magnitude and opposite in direction). Numerous common experiences, such as stubbing a toe or throwing a ball, confirm this. It is precisely stated in Newton's third law of motion. Newton's Third Law of Motion Whenever one body exerts a force on a second body, the first body experiences a force that is equal in magnitude and opposite in direction to the force that it exerts. This law represents a certain symmetry in nature: Forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself. We sometimes refer to this law loosely as "action-reaction," where the force exerted is the action and the force experienced as a consequence is the reaction. Newton's third law has practical uses in analyzing the origin of forces and understanding which forces are external to a system. We can readily see Newton's third law at work by taking a look at how people move about. Consider a swimmer pushing off from the side of a pool, as illustrated in Figure 4.9. She pushes against the pool wall with her feet and accelerates in the direction opposite to that of her push. The wall has exerted an equal and opposite force back on the swimmer. You might think that two equal and opposite forces would cancel, but they do not because they act on different systems. In this case, there are two systems that we could investigate: the swimmer or the wall. If we select the swimmer to be the system of interest, as in the figure, then F wall on feet is an external force... Q: Newton's third law of motion describes what property of forces that means balance? Choices: - acceleration - magnetism - gravity - symmetry A:

Ans:symmetry
