Answer the following question given this paragraph: What weighs about three pounds and contains up to 100 billion cells? The answer is the human brain. The brain is the control center of the nervous system. It's like the pilot of a plane. It tells other parts of the nervous system what to do. Q: Which organ is the control center of the nervous system? Choices: - the heart - the spine - the lungs - the brain A:
the brain

Answer the following question given this paragraph: Electricity and magnetism are inextricably linked. Under certain conditions, electric current causes a magnetic field. Under other conditions, a magnetic field can cause an electric current. A moving charged particle creates a magnetic field around it. Additionally, when a moving charged particle moves through a different magnetic field, the two magnetic fields will interact. The result is a force exerted on the moving charged particle. Q: Under certain conditions, electric current causes what type of field? Choices: - light - kinetic - seismic - magnetic A:
(Answer)
magnetic
Ques: Answer the following question given this paragraph: Introduction to Dynamics: Newton's Laws of Motion Motion draws our attention. Motion itself can be beautiful, causing us to marvel at the forces needed to achieve spectacular motion, such as that of a dolphin jumping out of the water, or a pole vaulter, or the flight of a bird, or the orbit of a satellite. The study of motion is kinematics, but kinematics only describes the way objects movetheir velocity and their acceleration. Dynamics considers the forces that affect the motion of moving objects and systems. Newton's laws of motion are the foundation of dynamics. These laws provide an example of the breadth and simplicity of principles under which nature functions. They are also universal laws in that they apply to similar situations on Earth as well as in space. Isaac Newton's (16421727) laws of motion were just one part of the monumental work that has made him legendary. The development of Newton's laws marks the transition from the Renaissance into the modern era. This transition was characterized by a revolutionary change in the way people thought about the physical universe. For many centuries natural philosophers had debated the nature of the universe based largely on certain rules of logic with great weight given to the thoughts of earlier classical philosophers such as Aristotle (384322 BC). Among the many great thinkers who contributed to this change were Newton and Galileo. Q: Whose laws of motion are the foundation of dynamics? Choices: - aristotle - einstein - bell - newton A:
Ans: newton

Answer the following question given this paragraph: Light with the longest wavelengths is called infrared light . The term infrared means "below red. " Infrared light is the range of light waves that have longer wavelengths and lower frequencies than red light in the visible range of light waves. The sun gives off infrared light as do flames and living things. You can't see infrared light waves, but you can feel them as heat. But infrared cameras and night vision goggles can detect infrared light waves and convert them to visible images. For a deeper understanding of infrared light, watch the video at this URL: http://www. youtube. com/watch?v=2--0q0XlQJ0 . Q: Light with the longest wavelengths is called what? Choices: - visible light - X-rays - UV light - infrared light A:
(A).
infrared light
Ques:Answer the following question given this paragraph: Q: Basidiomycetes do what to wood and other plant material? Choices: - evolve - revive - evaporate - decompose A:

Ans:decompose
Answer the following question given this paragraph: Destructive interference occurs when two waves combine and cancel each other out. This occurs when a peak in one wave lines up with a trough in the other wave. Q: What occurs when two waves combine and cancel each other out? Choices: - terrible interference - primitive interference - molecular interference - destructive interference A:
destructive interference
