Q: Telescopes use which kind of lenses to enlarge images? Read this paragraph and choose the correct option from the provided answers: Like microscopes, telescopes use convex lenses to make enlarged images. However, telescopes make enlarged images of objectssuch as distant starsthat only appear tiny because they are very far away. There are two basic types of telescopes: reflecting telescopes and refracting telescopes. The two types are compared in the Figure below . They differ in how they collect light, but both use convex lenses to form enlarged images. You can learn more about telescopes and how they evolved in the video at this URL:. Choices: - crystalline - spherical - concave - convex A:
convex

Q: What force explains why objects may float in water? Read this paragraph and choose the correct option from the provided answers: What explains buoyant force? Recall from the earlier lesson "Pressure of Fluids" that a fluid exerts pressure in all directions but the pressure is greater at greater depth. Therefore, the fluid below an object exerts greater force on the object than the fluid above the object. This is illustrated in Figure below . Buoyant force explains why objects may float in water. No doubt you've noticed, however, that some objects do not float in water. If buoyant force applies to all objects in fluids, why do some objects sink instead of float? The answer has to do with their weight. Choices: - warm force - cool force - gravity force - buoyant force A:
buoyant force

Q: Q: A few earthquakes take place away from plate boundaries, these are called what? Read this paragraph and choose the correct option from the provided answers: The remaining 5% are scattered around other plate boundaries. A few earthquakes take place away from plate boundaries. These are intraplate earthquakes. Choices: - outer earthquakes - deformation earthquakes - distant earthquakes - intraplate earthquakes A:
A: intraplate earthquakes

Question: Q: What is water vapor density known as? Read this paragraph and choose the correct option from the provided answers: saturation vapor density given in the table. Strategy To solve this problem, we need to break it down into a two steps. The partial pressure follows the ideal gas law,. Choices: - density - thickness - ambiance - humidity A:
Answer: humidity

Q: Mammalian lungs are located in what cavity, where they are surrounded and protected by the rib cage, intercostal muscles, and chest wall? Read this paragraph and choose the correct option from the provided answers: 39.3 | Breathing By the end of this section, you will be able to: Describe how the structures of the lungs and thoracic cavity control the mechanics of breathing Explain the importance of compliance and resistance in the lungs Discuss problems that may arise due to a V/Q mismatch Mammalian lungs are located in the thoracic cavity where they are surrounded and protected by the rib cage, intercostal muscles, and bound by the chest wall. The bottom of the lungs is contained by the diaphragm, a skeletal muscle that facilitates breathing. Breathing requires the coordination of the lungs, the chest wall, and most importantly, the diaphragm. Choices: - ventral - abdominopelvic - dorsal - thoracic A:
**Answer**
thoracic

Q: What will happen if the gas particles inside an inflated balloon suddenly stop moving? Read this paragraph and choose the correct option from the provided answers: Gas molecules also exert pressure. Earth's atmosphere exerts pressure because gravity acts on the huge number of gas particles contained in the atmosphere, holding it in place. Pressure is also exerted by a small sample of gas, such as that which is contained in a balloon. Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon's inner walls. It is those collisions which keep the balloon inflated. If the gas particles were to suddenly stop moving, the balloon would instantly deflate. The Figure below is an illustration of gas particles exerting pressure inside a container. Choices: - balloon falls - balloon bursts - balloon inflates - balloon deflates A:
(Answer)
balloon deflates
