Answer the following question given this paragraph: In 1905, the physicist Albert Einstein developed a new theory about electromagnetic radiation. The theory is often called the wave-particle theory . It explains how electromagnetic radiation can behave as both a wave and a particle. Einstein argued that when an electron returns to a lower energy level and gives off electromagnetic energy, the energy is released as a discrete "packet" of energy. We now call such a packet of energy a photon . According to Einstein, a photon resembles a particle but moves like a wave. You can see this in the Figure below . The theory posits that waves of photons traveling through space or matter make up electromagnetic radiation. Q: Einstein developed a theory about how electromagnetic radiation can behave as both a wave and what else? Choices: - energy - bacteria - sound - particle A:
(Answer)
particle

Answer the following question given this paragraph: Meningitis is an infection of the membranes that cover the brain and spinal cord. If you have meningitis, you are likely to have a fever and a headache. Another telltale symptom is a stiff neck. Meningitis can be caused by viruses or bacteria. Viral meningitis often clears up on its own after a few days. Bacterial meningitis is much more serious ( Figure below ). It may cause brain damage and death. People with bacterial meningitis need emergency medical treatment. They are usually given antibiotics to kill the bacteria. Q: Meningitis is an infection of the membranes that cover the brain and what else? Choices: - umbilical cord - notochord - liver - spinal cord A:
(A).
spinal cord
Ques:Answer the following question given this paragraph: All living things reproduce to make the next generation. Organisms that do not reproduce will go extinct. As a result, there are no species that do not reproduce ( Figure below ). Some organisms reproduce asexually ( asexual reproduction ), especially single-celled organisms, and make identical copies (or clones) of themselves. Other organisms reproduce sexually ( sexual reproduction ), combining genetic information from two parents to make genetically unique offspring. Q: What process do all species use to make the next generation? Choices: - separation - differentiation - variation - reproduction A:

Ans:reproduction
