Q: Answer the following question given this paragraph: The human eye can distinguish only red, green, and blue light. These three colors are called the primary colors of light. All other colors of light can be created by combining the primary colors. Look at the Venn diagram below . Red and green light combine to form yellow light. Red and blue light combine to form magenta light, and blue and green light combine to form cyan light. Yellow, magenta, and cyan are called the secondary colors of light. Look at the center of the diagram, where all three primary colors of light combine. The result is white light. You can explore the colors of visible light and how they combine at this URL: http://www. phy. ntnu. edu. tw/oldjava/color/color_e. html. Q: Which three colors are called the primary colors of light? Choices: - red, blue, yellow - black, white, red - blue, green, violet - red, green, blue A:
A: red, green, blue

Q: Answer the following question given this paragraph: The brain stem is the smallest of the three main parts of the brain. It lies directly under the cerebrum. The brain stem controls basic body functions, such as breathing, heartbeat, and digestion. The brain stem also carries information back and forth between the cerebrum and spinal cord. Q: What is the smallest main part of the brain? Choices: - the cortex - the claw - the cerebellum - the stem A:
A: the stem

Q: Answer the following question given this paragraph: Extending from the upper corners of the uterus are the two fallopian tubes. Each tube reaches (but is not attached to) one of the ovaries. The ovary end of the tube has a fringelike structure that moves in waves. The motion sweeps eggs from the ovary into the tube. Q: What pair of tubes that extends toward the ovaries features a fringelike structure that sweeps eggs inside? Choices: - golgi apparatus - ovarian tubes - vas deferens - fallopian tubes A:
A: fallopian tubes

Q: Answer the following question given this paragraph: Regardless of whether reactions are exothermic reactions or endothermic reactions , they all need energy to get started. This energy is called activation energy . Activation energy is like the push you need to start moving down a slide. The push gives you enough energy to start moving. Once you start, you keep moving without being pushed again. Activation energy is defined as the energy that must be overcome in order for a chemical reaction to occur, or the minimum energy required to start a chemical reaction. The concept of activation energy is illustrated in Figure below . Q: What do you call the energy that must be overcome in order for a chemical reaction to occur, or the minimum energy required to start a chemical reaction? Choices: - expression energy - phase energy - kinetic energy - activation energy A:
A: activation energy
