If you were to take a pH reading and compare the intermembrane space to the mitochondrial matrix (inner part of mitochondria), what would you expect?

What happens when an ammeter is set up in a parallel connection with the part of the circuit where you want to measure current?

(a) The ammeter gets a correct reading.

(b) The ammeter damages the circuit's voltage source.

(c) The ammeter reverses the current flow through the circuit.

(d) The ammeter creates a short circuit.

Grade 9 Science experiment:

Experiment:  Compare brands of paper towels, to see which holds the most liquid. The independent variable in your experiment would be the brand of paper towel. The dependent variable would be the amount of liquid absorbed by the paper towel.

Come up with a problem, explain how you are going to control the experiment using a dependent variable, and use appropriate formats for displaying the observed and recorded data.
