Two gases oxygen and nitrogen both of volumes 1dm*3 and 3.6dm*3 respectively. and mixed in a container. if the total pressure exerted by the mixture is 300pa. calculate the partial pressure of the two gases

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.
