In Felix County, the population of slugs has tripled.  Laura, who lives in the area, heard that salt may work to exterminate them.  To test this, she will use different amounts of kosher salt on the species of slug Slime slimosis.  All the slugs will be 10 days old and will weigh 10 grams.  To make sure the slugs will die from their exposure to salt and not because of other variables she also decides to observe 5 slugs that will not be exposed to the salt.  What is the independent variable?
a)
Amount of slugs
b)
The species Slime slimosis
c)
