Answer the following question given this paragraph: The epidermis is the outer layer of skin. It consists almost entirely of epithelial cells. There are no blood vessels, nerve endings, or glands in this skin layer. Nonetheless, this layer of skin is very active. It is constantly being renewed. How does this happen?. Q: Lacking blood vessels, nerve endings, or glands, the epidermis is the outer layer of what? Choices: - liver - brain - lungs - skin A:
(Answer)
skin
Ques: Answer the following question given this paragraph: Sebaceous glands produce an oily substance called sebum. Sebum is secreted into hair follicles and makes its way to the skin surface. It waterproofs the hair and skin and helps prevent them from drying out. Sebum also has antibacterial properties, so it inhibits the growth of microorganisms on the skin. Q: What kind of oily substance is secreted from sebaceous glands? Choices: - pus - Blood - progesterone - sebum A:
Ans: sebum

Answer the following question given this paragraph: Resistance is opposition to the flow of electric charges that occurs when electric current travels through matter. The SI unit of resistance is the ohm (named for the scientist Georg Ohm, whom you can read about below). Resistance is caused by electrons in a current bumping into electrons and ions in the matter through which the current is flowing. Resistance is similar to the friction that resists the movement of one surface as it slides over another. Resistance reduces the amount of current that can travel through the material because some of the electrical energy is converted to other forms of energy. For example, when electric current flows through the tungsten wire inside an incandescent light bulb, the tungsten resists the flow of electric charge, and some of the electrical energy is converted to light and thermal energy. Q: What term means opposition to the flow of electric charges that occurs when electric current travels through matter? Choices: - polarity - antagonism - diffusion - resistance A:
resistance
