You have two wires made of two different metals (metal A and metal B). Both wires are the same thickness and length. In one circuit, you use the metal A wire. In another identical circuit, you use the metal B wire. The metal A wire gets hot, while the metal B wire does not. Explain.

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.
