Answer the following question given this paragraph: Gas molecules also exert pressure. Earth's atmosphere exerts pressure because gravity acts on the huge number of gas particles contained in the atmosphere, holding it in place. Pressure is also exerted by a small sample of gas, such as that which is contained in a balloon. Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon's inner walls. It is those collisions which keep the balloon inflated. If the gas particles were to suddenly stop moving, the balloon would instantly deflate. The Figure below is an illustration of gas particles exerting pressure inside a container. Q: What will happen if the gas particles inside an inflated balloon suddenly stop moving? Choices: - balloon falls - balloon bursts - balloon inflates - balloon deflates A:
balloon deflates

Answer the following question given this paragraph: Figure 7.2 Axial and Appendicular Skeleton The axial skeleton supports the head, neck, back, and chest and thus forms the vertical axis of the body. It consists of the skull, vertebral column (including the sacrum and coccyx), and the thoracic cage, formed by the ribs and sternum. The appendicular skeleton is made up of all bones of the upper and lower limbs. Q: The appendicular skeleton is made up of all bones of the upper and lower what? Choices: - organs - hemispheres - digestive tract - limbs A:
limbs

Answer the following question given this paragraph: Measurement is the process of making an observation in terms of a numerical scale and recording the value. Q: What is the process of making an observation in terms of a numerical scale and recording the value? Choices: - ambient - respiration - graduation - measurement A:
measurement

Answer the following question given this paragraph: Amines are capable of hydrogen bonding though their boiling points are generally a bit lower than the corresponding alcohol. Methylamine and ethylamine are gases at room temperature, while larger amines are liquids. As with other organic compounds that form hydrogen bonds, water solubility is reflected in the length of the carbon chains. Smaller amines are soluble, while larger ones are less soluble. Q: As with other organic compounds that form hydrogen bonds, water solubility of amines is reflected in the length of what? Choices: - hydrocarbon bonds - complex carbohydrates - nuclei chains - carbon chains A:
carbon chains
