Remember that a controlled variable is a variable that stays the same thoughout the experiment.
it wouldn't be a. because two different wires were used
the final length of the wax would be your dependent variable, so it wouldn't be c.
the thermal conductivity is the independent variable so it isn't d.
the original length of the wax was the same for both.
So B is your answer.
C clouds
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals
Mendel observed phenotypic traits during the cross of pea plants. Subsequently, he noted each trait had only two forms.
<h3>Mendel's Experiments</h3>
Mendel crossed pure-breeding pea plants, and then he crossed hybrid generations, as well crossed the hybrid progeny back to parental lines.
From these crosses, Mendel observed the descendence and then formulated a series of inheritance principles.
Mendel noted traits can be divided into dominant and recessive phenotypic characteristics.
Dominant characteristics were inherited in an unaltered manner after hybridization of true breeding [plants.
