A team of biology students performed an experiment to test the effects of four different solutions on the volume of a raw chicken egg. Each raw chicken egg was identical in size. They were placed in four individual containers, holding four different solutions. Twenty-four hours later the following results we obtained. What is the test (independent) variable in this experiment?
Group of answer choices

The type of eggs used.

The mass of the eggs used

The different solutions

The final volume of the eggs.

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.

What is the difference between a substance "getting wet" and "being dissolved" in a liquid at the particulate level?
