Q: Answer the following question given this paragraph: A: Variables might include factors relating to the ramp or to the object. An example of a variable relating to the ramp is its steepness. An example of a variable relating to the object is the way it movesit might roll or slide down the ramp. Either of these variables could be manipulated by the researcher, so you could choose one of them for your manipulated variable. Q: An example of a variable relating to the ramp is its what? Choices: - color - mass - weight - steepness A:
A: steepness

Q: Answer the following question given this paragraph: When gas molecules bump into things, it creates pressure. Pressure is greater when gas molecules occupy a smaller space, because greater crowding results in more collisions. This explains why decreasing the volume of a gas increases its pressure. Q: Decreasing the volume of a gas and keeping everything else the same will cause its pressure to change in what way? Choices: - heat up - decrease - lower - increase A:
A: increase

Q: Answer the following question given this paragraph: The plasma membranes of cells that specialize in absorption are folded into fingerlike projections called microvilli (singular = microvillus). This folding increases the surface area of the plasma membrane. Such cells are typically found lining the small intestine, the organ that absorbs nutrients from digested food. This is an excellent example of form matching the function of a structure. People with celiac disease have an immune response to gluten, which is a protein found in wheat, barley, and rye. The immune response damages microvilli, and thus, afflicted individuals cannot absorb nutrients. This leads to malnutrition, cramping, and diarrhea. Patients suffering from celiac disease must follow a gluten-free diet. Q: People with celiac disease have an immune response to what, which ultimately leads to malnutrition, cramping, and diarrhea? Choices: - fish - lactose - seeds - gluten A:
A: gluten
