The variables are
the number of dry cells connected end to end
the duration of the light bulb working</span><span />

Explanation:
do you mean
this question??
Experiment 1: A group of students tested to see if the acidity of water affected pea plant growth. The students followed a logical method and performed their experiment once, using control and experimental groups. Their results supported their hypothesis.
Experiment 2: A group of students tested to see if bacteria growth in water was affected by acidity. The students used control and experimental groups. They repeated their experiment several times and found the results were the same.
Which experiment most likely has greater reliability?
A. Number 1 because it follows a logical method
B. Number 2 because the experiment was repeated
C. Number 2 because the experiment was repeated and the results were always the same
D. Number 1 because it has control groups
