Answer the following question given this paragraph: Fats may be either saturated or unsaturated. A saturated fat is a fat that consists of triglycerides whose carbon chains consist entirely of carbon-carbon single bonds. Therefore, the carbon chains are saturated with the maximum number of hydrogen atoms possible. An unsaturated fat is a fat that consists of triglycerides whose carbon chains contain one or more carbon-carbon double bonds . A fat with one double bond is called monounsaturated, while a fat with multiple double bonds is called polyunsaturated (see Figure below ). Q: What are the two types of fats? Choices: - thick and thin - full and empty - liquid and solid - saturated and unsaturated A:
saturated and unsaturated

Answer the following question given this paragraph: The muscular system consists of all the muscles of the body. Muscles are organs composed mainly of muscle cells, which are also called muscle fibers . Each muscle fiber is a very long, thin cell that can do something no other cell can do. It can contract, or shorten. Muscle contractions are responsible for virtually all the movements of the body, both inside and out. There are three types of muscle tissues in the human body: cardiac, smooth, and skeletal muscle tissues. They are shown in Figure below and described below. Q: What are muscle cells in the muscles called? Choices: - human fibers - use fibers - job fibers - muscle fibers A:
muscle fibers

Answer the following question given this paragraph: Q: Other than nitrogen, which nutrient most often limits marine production? Choices: - potassium - zinc - calcium - phosphorus A:
phosphorus

Answer the following question given this paragraph: Electrons are always added to the lowest energy level first until it has the maximum number of electrons possible, and then electrons are added to the next higher energy level until that level is full, and so on. The maximum number of electrons at a given energy level depends on its number of orbitals. There are at most two electrons per orbital. Q: Electrons are always added to which energy level first? Choices: - the highest - the second - the major - the lowest A:
the lowest
