The independent variable in the hypothesis of an observed increased in sea turtle sickness once an increase in red tide can be seen would be the increase of red tide.
The reason for this is that red tide increases or decreases will happen independently of the amount of sea turtle sickness - therefore increasing sea turtle sickness will be dependent on the first variable. (independent one).
That would be catalysts.
Catalysts accelerate (speed up) chemical reactions without damaging itself. They do this by decreasing the activation energy of a chemical reaction.
Enzymes are a type of catalysts.
