Question: Answer the following question given this paragraph: of pivot point, and so we choose the pivot point to simplify the solution of the problem. Second, the acceleration due to gravity canceled in this problem, and we were left with a ratio of masses. This will not always be the case. Always enter the correct forcesdo not jump ahead to enter some ratio of masses. Third, the weight of each child is distributed over an area of the seesaw, yet we treated the weights as if each force were exerted at a single point. This is not an approximationthe distances r 1 and r 2 are the distances to points directly below the center of gravity of each child. As we shall see in the next section, the mass and weight of a system can act as if they are located at a single point. Finally, note that the concept of torque has an importance beyond static equilibrium. Torque plays the same role in rotational motion that force plays in linear motion. We will examine this in the next chapter. Take-Home Experiment Take a piece of modeling clay and put it on a table, then mash a cylinder down into it so that a ruler can balance on the round side of the cylinder while everything remains still. Put a penny 8 cm away from the pivot. Where would you need to put two pennies to balance? Three pennies?. Q: What plays the same role in rotational motion that force plays in linear motion. A:
OPTIONS:
- efficiency
- frame
- fulcrum
- torque
Answer: torque

input with options: Answer the following question given this paragraph: Photosynthesis and cellular respiration are connected through an important relationship. This relationship enables life to survive as we know it. The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis :. Q: Which process acts as a natural complement for cellular respiration? A:
OPTIONS:
- glycolysis
- atherosclerosis
- absorption
- photosynthesis
output: photosynthesis

Q: Answer the following question given this paragraph: Adolescence includes the physical changes of puberty among other changes. Q: Puberty and other physical changes occurs during which stage of development? A:

OPTIONS:
- childhood
- infancy
- adulthood
- adolescence

A: adolescence

input: OPTIONS:
- intestines
- brain
- stomach
- mouth Now, answer this question: Answer the following question given this paragraph: The mouth also begins the process of mechanical digestion . Sharp teeth in the front of the mouth cut or tear food when you bite into it (see Figure below ). Broad teeth in the back of the mouth grind food when you chew. Food is easier to chew because it is moistened by saliva from the salivary glands. The tongue helps mix the food with saliva and also helps you swallow. After you swallow, the chewed food passes into the pharynx. Q: Where does mechanical digestion begin? A:
A:
output: mouth

Answer the following question given this paragraph: Fossils are the preserved remains of animals, plants, and other organisms from the distant past. Examples of fossils include bones, teeth, and impressions. By studying fossils, evidence for evolution is revealed. Paleontologists are scientists who study fossils to learn about life in the past. Fossils allow these scientists to determine the features of extinct species. Paleontologists compare the features of species from different periods in history. With this information, they try to understand how species have evolved over millions of years ( Figure below ). Q: What are the preserved remains of animals, plants, and other organisms called? A:

OPTIONS:
- skulls
- rocks
- basalt
- fossils

Answer: fossils

Q: Answer the following question given this paragraph: Lifecycle of Leukocytes Most leukocytes have a relatively short lifespan, typically measured in hours or days. Production of all leukocytes begins in the bone marrow under the influence of CSFs and interleukins. Secondary production and maturation of lymphocytes occurs in specific regions of lymphatic tissue known as germinal centers. Lymphocytes are fully capable of mitosis and may produce clones of cells with identical properties. This capacity enables an individual to maintain immunity throughout life to many threats that have been encountered in the past. Q: Characterized by a short lifespan, what begin with production in the bone marrow under the influence of csfs and interleukins? A:

OPTIONS:
- solutes
- pathogens
- erythrocytes
- leukocytes

A:
leukocytes
