Which substance is the solute?, Glass, Water, Sugar, Sugar solution, What is the main purpose of cell division in multicellular organisms?, To produce food, To help organisms grow and repair damaged tissues, To change cells into bacteria, To remove all chromosomes, A group of Grade 7 students wanted to investigate whether sunlight affects the growth of mung bean plants. They wrote the question, "How does the amount of sunlight affect the height of mung bean plants?" Which part of the scientific investigation does this represent?, Materials and Equipment, Results, Aim or Problem, Conclusion, Which microscope part is used to look through the microscope?, Objective lens, Stage, Eyepiece, Diaphragm, Which type of cell division produces two genetically identical daughter cells?, Meiosis, Mitosis, Sexual reproduction, Fertilization, Ben prepares powdered juice by mixing the powder with water. In this solution, the water acts as the _______., Solvent, Solute, Precipitate, Residue, A student accidentally left a bottle of water inside the freezer overnight. The next morning, the liquid had turned into solid ice. Which change of state occurred?, condensation, melting, sublimation, freezing, A student observes a green structure inside a plant cell. Which organelle is most likely being observed?, mitochondrion, nucleus, chloroplast, cell membrane, Which type of reproduction involves only one parent?, meiosis, asexual reproduction, fertilization, sexual reproduction, Before conducting an investigation, Lea listed a ruler, three beakers, water, soil, and mung bean seeds. Which part of the investigation is she preparing?, conclusion, materials and equipment, result, aim, During which stage of mitosis do chromosomes line up at the middle of the cell?, Prophase, Anaphase, Metaphase, Telophase, Carlo places blue litmus paper into vinegar. The paper turns red. What does this indicate?, Vinegar is a base., Vinegar is a salt., Vinegar is an acid., Vinegar is neutral., Which cell structure contains the genetic material and controls many cell activities?, nucleus, cell wall, cytoplasm, chloroplast, How many daughter cells are produced at the end of meiosis?, four, three, two, one, A student wants to change from low magnification to high magnification. Which microscope part should be rotated?, Stage clips, revolving nosepiece, base, arm, A farmer grows a new plant from a stem cutting of an existing plant. Which type of reproduction is this?, fertilization, asexual reproduction, meiosis, sexual reproduction, A student adds more and more salt to a glass of water. Eventually, some salt remains at the bottom. What does this indicate?, The solution has reached its solubility limit., The water has disappeared., The water has become a gas., The salt has become a solvent., Which microscope part holds the slide in place?, Stage clips, Eyepiece, Arm, Coarse adjustment knob, Which type of reproduction usually involves the joining of male and female gametes?, Binary fission, Budding, Sexual reproduction, Vegetative propagation, During a science activity, Josh carefully placed a paper clip on the surface of still water. The paper clip floated because the surface of the water resisted breaking. What property of liquids explains this observation?, Viscosity, Surface tension, Pressure, Boiling, Lea notices that sugar dissolves faster in hot water than in cold water. Which factor affected the dissolving process?, Pressure, Temperature, Color, Container size, During a microscope activity, students observe a cell structure that controls the movement of substances into and out of the cell. This structure is the cell wall., TRUE, FALSE, During an experiment, Kristoff followed a series of numbered instructions exactly as written to ensure accurate results. Which part of the investigation was being followed?, Results, Procedures, Aim, Conclusion, Which of the following is an example of asexual reproduction?, A human baby produced from sperm and egg, A flowering plant producing seeds after fertilization, A bacterium dividing into two cells, Two animals producing offspring, A cell needs energy to carry out its activities. Which organelle is mainly responsible for releasing usable energy from food?, Mitochondrion, Nucleus, Chloroplast, Cell membrane, A student observes a jelly-like material filling the inside of a cell. What is this material called?, Cell wall, Nucleus, Cytoplasm, Chloroplast, A student claims that evaporation and boiling are exactly the same because both produce water vapor. Which statement best corrects the student's idea?, Evaporation occurs only inside a closed container., Boiling happens only in cold water., Evaporation occurs at the surface, while boiling occurs throughout the liquid., Both occur only at the boiling point., A student tests a soap solution using red litmus paper. The paper turns blue. What can the student conclude?, The solution is salt., The solution contains no water., The solution is acidic., The solution is basic., Which of the following is a gamete?, egg cell, nerve cell, skin cell, plant cell, During a science activity, students used a globe to identify continents, oceans, and Earth's rotation. Why is the globe considered a physical model?, It uses mathematical equations., It only shows the movement of particles., It represents a real object in a smaller form., It explains ideas using words.
