A science student observes that a dissolvable antacid tablet acts faster in relieving stomach pain when taken with warm water than when taken
with water at room temperature. Based on the observation, suggest a potential problem that can be studied. Also, list the dependent
independent, and controlled variables that can exist in such an investigation.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
