question 14 (2 points)
of the following, the only unit that cannot be used to express volume is____

question 15 (2 points)
a testable prediction is a(n) ____

Explanation:

• For the first question, a derived unit is formed by combining other units. For example, in the SI system, speed (m/s) is derived from length (meters) and time (seconds).
• For the second question, kg is the SI - unit of mass, not volume. Liters (L), cubic centimeters (cm³), and milliliters (mL) are all units of volume.
• For the third question, a hypothesis is a testable prediction. An experiment is a procedure to test a hypothesis, an exercise is a general activity, and a variable is a factor that can change in an experiment.

Answer:

• Question 1: D. derived
• Question 2: A. kg
• Question 3: A. hypothesis
