[EX Q]: The dermis is the inner layer of skin. The dermis has blood vessels and nerve endings. The nerve endings explain why your skin is sensitive. You can sense pain, pressure, and temperature. You cut your finger and it starts to bleed. What has happened? If your skin bleeds, it means you have cut the dermis layer and damaged blood vessels. The cut really hurts. It hurts because of the nerve endings in this skin layer. The dermis also contains hair follicles and two types of glands. Hair follicles are structures where hairs originate. Each hair grows out of a follicle. Hair passes up through the epidermis. It then extends above the skin surface. Oil glands produce an oily substance. The oil is secreted into hair follicles. <sep>How is the dermis related to skin sensitivity?<sep>Because it is sensitive
[EX A]: No

[EX Q]: Do all plants live on the land? Some plants do live in the water. To do this, they have evolved special traits. Plants that live in water are called aquatic plants. Living in water has certain benefits. There is certainly plenty of water! The plant does not need special traits to absorb, transport, or conserve water. They do not need a large root system. They do not need a strong stem to hold up the plant. The plant uses the water for support. Dont think water plants have it easy, though. They also face challenges. Living in water isnt that easy. They do need some special traits to survive. It is tough for the plant to reproduce. Pollination by wind or animals cant happen under water. Sunlight cannot reach very far beneath the waters surface. Some aquatic plants have floating flowers and leaves. <sep>How is an aquatic plant held up?<sep>Roots
[EX A]: No

[EX Q]: Light rays strike a reflecting surface. They are then reflected back. You can predict the angle of the reflected light. Imagine a ball bouncing off a surface. Light can do the same thing. That is, assuming the surface is shiny. So how do you know where light will go after it strikes a shiny surface? It depends on how the light initially strikes the shiny object. Light does not always go straight toward a surface. Therefore, not all light bounces straight back. Sometimes, light can hit a surface at an angle. The angle at which it strikes the surface tells us how it will bounce off. While light is different to a ball, they react in a similar manner. Many sports rely on knowledge of reflection. Pool players know a lot about reflection. They take great care when they strike the pool ball. They need it to go to a certain place. They know the angle it will hit the side of the pool table. <sep>What information is useful to pool players when they strike a ball?<sep>they need to know how to strike a ball in soccer
[EX A]:
No
