Thick - 80%
a. the number of insects
b. the thickness of the exoskeleton
c. the survival rate of the insects

The independent variable in this study is **b. the thickness of the exoskeleton**.
This is the variable that the researcher manipulates or categorizes in order to observe its effect on the dependent variable, which in this case is the survival rate of the insects.
