Answer the following question given this paragraph: Smooth muscles and cardiac muscles are not attached to bone. Recall that these types of muscles are under involuntary control. Smooth muscle is responsible for the contractility of hollow organs, such as blood vessels, the gastrointestinal tract, the bladder, or the uterus. Like skeletal muscles, smooth muscle fibers do contract together, causing the muscle to shorten. Smooth muscles have numerous functions, including the following. Q: What kind of muscle is responsible for hollow organs contracting? Choices: - micro muscle - tough muscle - rough muscle - smooth muscle A:
smooth muscle

Answer the following question given this paragraph: In some ways, a collection of gas molecules represents the simplest form of matter. Because the individual molecules are so far apart, they have only fleeting interactions with one another. In contrast, molecules that have clustered together to form a liquid or solid are constantly exerting forces on each other. In fact, it is only because of these attractive forces that molecular solids and liquids exist at all. In this lesson, we will look at some of the ways in which molecules and ions attract one another to form solids and liquids. Q: In some ways, a collection of gas molecules represents the simplest form of what? Choices: - life - energy - protein - matter A:
matter
