Ball P went twice as high as Ball NBall M went twice as high as Ball NBall P went two meters higher than Ball OBall N went two meters higher than Ball O 2 John wants to build a racetrack that will allow his toy cars to travel fast when force is applied? Which material should he use? Carpet, because friction will be highGravel, because friction will be highPlastic, because friction will be lowSandpaper, because friction will be low 3 A magnet is placed near a pile of steel paper clips. Which will MOST LIKELY occur? The magnet will provide a balanced force, causing the paper clips to spin in circles.The magnet will provide an unbalanced force, keeping the paper clips stationary.The magnet will provide a balanced force, pushing the paper clips away from it.The magnet will provide an unbalanced force, pulling the paper clips toward it. 4 If a 21. 7-kg ball located on a shelf 1. 6m above the ground... Which BEST describes the energy of the ball? Its energy is lost once it falls off the shelf.Its energy depends upon the speed the ball will travel.It has mechanical energy in the form of potential energy.It has mechanical energy in the form of kinetic energy. 5 As a roller coaster car travels down a hill, which type of change in energy allows it to speed up? Potential energy changing into heat energyPotential energy changing into kinetic energyKinetic energy changing into heat energyKinetic energy changing into potential energy 6 Which form of energy does a car's energy convert into mechanical energy? LightWindChemicalGravitational 7 Which type of energy is changed by plants into chemical energy? SolarNuclearThermalGravitational 8 How can an inclined plane make work easier? By increasing the amount of friction necessary for the taskBy increasing the effort necessary to raise an objectBy decreasing the effort necessary to raise an objectBy decreasing the efficiency of the task 9 Which occurs within a high-pressure system? The formation of tornadoesThe formation of hurricanesLarge clouds, as air risesCalm weather, as air sinks 10 How does the convection of air produce thunderstorms? By causing warm air to sink as cold air risesBy causing warm air to rise as cold air sinksBy causing both war air and cold air to riseBy causing both warm air and cold air to sink 11 Which BEST explains how the Coriolis effect influences weather conditions? It causes wind to rotate , forming tornadoes on EarthIt causes wind to move to the right in the Southern HemisphereIt causes winds to move to the right in the Northern HemisphereIt causes winds to follow a straight-line path around Earth. 12 Why is it important for th eU. S to monitor air pollution levels in other countries? Air pollution can improve the ozone layer amounts in the atmosphereAir pollution can travel to the U. S and affect people's healthThe U. S is the only country that can monitor air quality.The U, S has clean air and is able to help other countries. 13 How do an amoeba, euglena and paramecium compare? They use different structures for movementThe use different structures ot control cell activityThey all make their own food by photosynthesisThey all have eyespots to sense sunlight. 14 In a plant cell, it has a mitochondria, a nucleus, a vacuole and a chloroplast. Which organelle is used to transfer energy and can also be found in an animal cell? MitochodrionNucleusVacuoleChloroplast 15 The cell membrane is unable to work properly. How could this affect plant and animal cells? It could affect their ability to absorb sunlightIt could affect their ability to make proteinsIt could affect their ability to store waterIt could affect their ability to remove waste 16 Which Best summarizes organ systems? A group of organelles working together to perform a certain jobA group of tissues working together to perform a certain jobA group of organs working together to perform a certain jobA group of cells working together to perform a certain job 17 Which function summarizes the excretory system? It removes wasteIt collects oxygenIt attacks diseasesIt delivers nutrients 18 How do the respiratory and circulatory systems work together> The respiratory system takes in carbon dioxide, while the circulatory system delivers carbon dioxide to the cellsThe circulatory system takes in carbon dioxide, while the respiratory system delivers carbon dioxide to the cellsThe respiratory system takes in oxygen, while the circulatory system delivers oxygen to the cells.The circulatory takes in oxygen, while the respiratory system delivers it to the cells. 19 How does mitosis compare to meiosis? Mitosis produces 2 identical daughter cells, while meiosis produces sex cells with half the genetic informationMitosis produces sex cells with half genetic information, while meiosis produces 2 identical daughter cellsMitosis occurs only in single celled organisms, while meiosis only occurs in animalsMitosis only occurs in animals, while meiosis only occurs in single-celled organisms.
