5 IRETIONS Read each question and choose the best answer. Then fill in the correct answer on your answer document. SMPLE SMPLE When a 10% hydrochloric acid solution is heated in an open test tube, the test tube should always be pointed so bubbles are visible at a 180º angle from the flame toward a ventilated area away from nearby people MSS = 40 g VOLUME = 20 ml The picture shows a cube that contains 20 ml of a solution. The solution has a mass of 40 grams. What is the density in g/ml of this solution? Record and bubble on the answer document. Page 3

6 1 Students in a biology class carefully measured out an amount of soil and placed it in an oven where it was heated to remove any water. Which of the following tools is best used to measure the mass of the water that was removed from the soil? Group F G H J Listing from simplest to most complex cells, organs, tissues, organ systems, organisms cells, tissues, organs, organ systems, organisms * tissues, cells, organs, organ systems, organisms tissues, organs, cells, organ systems, organism 2 Students in a biology class were divided into groups and asked to sequence the different levels of organization in multicellular organisms. Which group correctly completed the task? cm Images ourtesy of TE Page 4

7 3 Ingredients in food products are listed in order from the greatest amounts to the least amounts. elow are labels from four different brands of the same type cereal. If you needed a cereal low in added sugar, which one would you select? Nutrition Facts Ingredients: Whole Wheat Rice Wheat ran Raisins ates Sugar Vitamins Minerals Nutrition Facts Ingredients: Whole Wheat Wheat ran Raisins Rice Sugar ates Vitamins Minerals Nutrition Facts Ingredients: Whole Wheat Wheat ran Sugar Raisins Rice ates Vitamins Minerals Nutrition Facts Ingredients: Sugar Whole Wheat Wheat ran ates Raisins Rice Vitamins Minerals Page 5

8 Time istance Final Speed (s) (m) (m/s) The data in the table was from a lab activity to analyze the motion of a ball. The acceleration of the ball was F 1.5 m/s 2 G 5 m/s 2 H 10 m/s 2 J 15 m/s 2 5 soccer player kicks a soccer ball with his foot. If the force of his foot on the ball is considered the action force, what is the reaction force? The force that his other foot exerts on the ground. The force the ball exerts on his foot. The force on the hand of the person who catches it. The force of the ball on the air. 6 group of students are working together in the laboratory. Two group members each fill a test tube with a different clear liquid and place them in a test tube rack. The test tubes are not labeled, and soon the students realize that they don t know which is which. What should they do? F G H J omplete the lab activity and try to identify the substances from the results. Try to remember which test tube is which, and then label them. Smell and taste both liquids to identify them, and then label the test tubes. sk the instructor to dispose of both liquids and obtain new samples in labeled test tubes. Page 6

The amplitude of this wave is 2 m 4 m 6 m 8 m pplied force 8 The mechanical advantage of a simple machine, like the lever shown above, is a measure of how much the simple machine changes the force or distance of the input. The lever is balanced in the center like a seesaw, and a worker uses the lever to lift a heavy box. If you compare the weight of the box to the force the worker must apply and assume no friction, the mechanical advantage of this simple machine would be approximately F 3 G 2 H 5 J 1 Page 7

N Protein RN Protein RN N N RN Protein RN Protein N 12 Which of the following is a primary function of carbohydrates? F Storage of energy * G H J Transmission of genetic material cceleration of chemical reactions Transportation of molecules 10 Which of the following is an example of a prokaryotic organism? F G H J elery Horse acterium Mushroom 13 student designed an experiment using three Petri dishes that had been inoculated with bacteria commonly found in the mouth. The student placed 2 ml of three different concentrations of saltwater in each dish. What is the experiment being designed to answer? Which concentration of saltwater is best for fighting bacteria? How much saltwater is needed to kill bacteria? Which type bacteria is most affected by saltwater? o bacteria like one concentration of saltwater better than another? Massachusetts ept. of Education 11 The picture above shows a duck swimming in a lake. student sees an image of the duck in the water. What causes this image to form? iffused light Refracted light Reflected light * bsorbed light 14 The driver of a taxi stops to pick up a large family with many pieces of heavy luggage. ased on Newton's second law of motion, the driver should expect that the taxi will F G H J take longer to travel the same distance take longer to both accelerate and stop require less energy to keep moving develop more stopping friction Page 8

11 15 In an experiment, chickens were fed corn that contained a chemical marker in its proteins. The presence of the marker can be detected in organisms. Some of the chickens were eaten by wolves. Which of the following would be considered a valid conclusion from this experiment? The marker will only be found in the corn. The marker will only be found in the wolf's wastes. Wolves will have the marker, but chickens will not. oth chickens and wolves will have the marker. Page 9
