Answer the following question given this paragraph: Pressure and temperature are directly proportional at a constant volume. Q: Pressure and ________ are directly proportional at a constant volume? Choices: - heating - precipitation - speed - temperature A:
temperature
Q: Answer the following question given this paragraph: The concentration of hydronium ions in a solution is known as acidity. In pure water, the concentration of hydronium ions is very low; only about 1 in 10 million water molecules naturally breaks down to form a hydronium ion. As a result, pure water is essentially neutral. Acidity is measured on a scale called pH , as shown in Figure below . Pure water has a pH of 7, so the point of neutrality on the pH scale is 7. Q: What is the scale on which acidity is measured? Choices: - m - hp - g - ph A:
A: ph
Question: Answer the following question given this paragraph: Compound machines generally have lower efficiency but greater mechanical advantage than simple machines. Q: What type of machines generally have lower efficiency but greater mechanical advantage? Choices: - calculation machines - simple machines - radical machines - compound machines A:
Answer: compound machines

Answer the following question given this paragraph: Superior Rotation and Inferior Rotation Superior and inferior rotation are movements of the scapula and are defined by the direction of movement of the glenoid cavity. These motions involve rotation of the scapula around a point inferior to the scapular spine and are produced by combinations of muscles acting on the scapula. During superior rotation, the glenoid cavity moves upward as the medial end of the scapular spine moves downward. This is a very important motion that contributes to upper limb abduction. Without superior rotation of the scapula, the greater tubercle of the humerus would hit the acromion of the scapula, thus preventing any abduction of the arm above shoulder height. Superior rotation of the scapula is thus required for full abduction of the upper limb. Superior rotation is also used without arm abduction when carrying a heavy load with your hand or on your shoulder. You can feel this rotation when you pick up a load, such as a heavy book bag and carry it on only one shoulder. To increase its weight-bearing support for the bag, the shoulder lifts as the scapula superiorly rotates. Inferior rotation occurs during limb adduction and involves the downward motion of the glenoid cavity with upward movement of the medial end of the scapular spine. Q: Inferior rotation occurs during limb adduction and involves the downward motion of what? Choices: - choroidal cavity - pelvic cavity - dialysate cavity - glenoid cavity A:
**Answer**
glenoid cavity
