Q: What does burning wood release into the atmosphere? Read this paragraph and choose the correct option from the provided answers: Forests are also being destroyed. Trees may be cut down for their wood, or they may be burned to clear the land for farming. Burning wood releases more carbon dioxide into the atmosphere.

For example, cardiovascular and respiratory systems work together to provide the individual with oxygen and rid it of carbon dioxide. Choices: - maturation systems - digestive systems - heartbeat systems - organ systems A:

Ans:organ systems

Question: Q: What do cyclotrons use to cause particles to move in circular orbits? Read this paragraph and choose the correct option from the provided answers: Figure 33.8 Cyclotrons use a magnetic field to cause particles to move in circular orbits. As the particles pass between the plates of the Ds, the voltage across the gap is oscillated to accelerate them twice in each orbit. Choices: - layers field - occurs field - mixed field - magnetic field A:
Answer:
magnetic field
