Answer the following question given this paragraph: A lens that causes the light rays to bend away from its axis is called a diverging lens. Ray tracing is the technique of graphically determining the paths that light rays take. The image in which light rays from one point on the object actually cross at the location of the image and can be projected onto a screen, a piece of film, or the retina of an eye is called a real image. Thin lens equations are. Q: What do you call a lens that causes the light rays to bend away from its axis? Choices: - optical lens - axilens - converging lens - diverging lens A:
diverging lens
Q: Answer the following question given this paragraph: recycling: Takes used items and materials and turns it into something new. For example, 98% of car batteries are recycled today. In the processing plant, the plastic materials are separated from the lead, so the plastic can then be used for many applications. Q: What term means taking used items and materials and turning them into something new? Choices: - reproducing - collecting - feeding - recycling A:
A: recycling

Answer the following question given this paragraph: Apocrine secretion accumulates near the apical portion of the cell. That portion of the cell and its secretory contents pinch off from the cell and are released. The sweat glands of the armpit are classified as apocrine glands. Both merocrine and apocrine glands continue to produce and secrete their contents with little damage caused to the cell because the nucleus and golgi regions remain intact after secretion. In contrast, the process of holocrine secretion involves the rupture and destruction of the entire gland cell. The cell accumulates its secretory products and releases them only when it bursts. New gland cells differentiate from cells in the surrounding tissue to replace those lost by secretion. The sebaceous glands that produce the oils on the skin and hair are holocrine glands/cells (Figure 4.11). Q: The sweat glands of the armpit are classified as these? Choices: - mucus glands - pineal glands - adrenal glands - apocrine glands A:
**Answer**
apocrine glands
