You can read about generators and how they work in the chapter "Electromagnetism. ". Q: Through a process called electromagnetic induction, generators change what energy form of a spinning turbine to electrical energy? Choices: - potential - seismic - electric - kinetic A:
(Answer)
kinetic
Ques: Answer the following question given this paragraph: Symbiosis is a close relationship between two species in which at least one species benefits. Q: What is a close relationship between two species in which at least one species benefits? Choices: - endosymbiosis - parasitism - morphogenesis - symbiosis A:
Ans: symbiosis
(Q).
Answer the following question given this paragraph: The stratosphere contains a layer of ozone gas. Ozone consists of three oxygen atoms (O 3 ). The ozone layer absorbs high-energy UV radiation. As you can see in Figure below , UV radiation splits the ozone molecule. The split creates an oxygen molecule (O 2 ) and an oxygen atom (O). This split releases heat that warms the stratosphere. By absorbing UV radiation, ozone also protects Earth's surface. UV radiation would harm living things without the ozone layer. Q: What is the name for the stratospheric gas layer that protects living things from uv radiation? Choices: - carbon layer - atmospheric layer - toposphere - ozone layer A:
(A).
ozone layer
Ques:Answer the following question given this paragraph: You generally can't see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below. Q: What does the geiger counter detect? Choices: - vibration - convection - moisture - radiation A:

Ans:radiation
Question: Answer the following question given this paragraph: Spinal Cord Development While the brain is developing from the anterior neural tube, the spinal cord is developing from the posterior neural tube. However, its structure does not differ from the basic layout of the neural tube. It is a long, straight cord with a small, hollow space down the center. The neural tube is defined in terms of its anterior versus posterior portions, but it also has a dorsalventral dimension. As the neural tube separates from the rest of the ectoderm, the side closest to the surface is dorsal, and the deeper side is ventral. As the spinal cord develops, the cells making up the wall of the neural tube proliferate and differentiate into the neurons and glia of the spinal cord. The dorsal tissues will be associated with sensory functions, and the ventral tissues will be associated with motor functions. Q: The spinal cord develops, cells making up the wall of the neural tube proliferate and differentiate into what? Choices: - membrane and glia - muscles and glia - jelly and glia - neurons and glia A:
Answer:
neurons and glia
