Answer the following question given this paragraph: A neon light produces visible light by electroluminescence. In this process, neon or some other gas gives off light when an electric current passes through it. Other halogen gases besides neonincluding krypton and argonalso produce light in this way. The word "OPEN" in the sign below is a neon light. It is a long glass tube that contains neon gas. When electricity passes through the gas, it excites electrons of neon atoms, and the electrons jump to a higher energy level. As the excited electrons return to their original energy level, they give off visible light. Neon produces red light. Other gases produce light of different colors. For example, krypton produces violet light, and argon produces blue light. Q: Neon, krypton and argon are examples of what kind of gases, which produce light by electroluminescence? Choices: - radiation gases - ionic gases - irradiation gases - halogen gases A:
(Answer)
halogen gases

Ques:Answer the following question given this paragraph: Still other pathogens are spread by vectors. A vector is an organism that carries pathogens from one person or animal to another. Most vectors are insects such as ticks or mosquitoes. They pick up pathogens when they bite an infected animal and then transmit the pathogens to the next animal they bite. Ticks spread the bacteria that cause Lyme disease. Mosquitoes spread the protozoa that cause malaria. Q: An organism that carries pathogens from one individual to another is called what? Choices: - germ cell - virus - host - vector A:

Ans:vector
Answer the following question given this paragraph: Cellular respiration and photosynthesis are direct opposite reactions. Energy from the sun enters a plant and is converted into glucose during photosynthesis. Some of the energy is used to make ATP in the mitochondria during cellular respiration, and some is lost to the environment as heat. Q: During photosynthesis, what is energy from the sun converted to after entering a plant? Choices: - Carbon - chloride - Proteins - glucose A:
glucose
