The liver is at a #3 level of organization, an organ..which has a specific job to do in the body.
Although the actual questions are missing from your ask, here's how you can tell.
If the study will be messed up (added bias) through interaction with the subjects the study should be observational. For example if a biologists wanted to study the eating habits of wild birds in the tropics, they would need to do an observational study. if they did a controlled experiment, the birds will change their eating habits based on human interaction, thus making the study invalid.
If the study requires specific measurements, close monitoring, or contact and interaction with the subjects the study should be a controlled experiment. For example, if a scientist wanted to test out a new drug, the health of patients would need to be closely monitored.

The Golgi complex is responsible for taking proteins that have been built and essentially "shipping" them by putting them in fluid surrounded by lipid layer for transport. These transports are called vesicles. The Golgi complex is like a post office or pack-ship store that packages and sends the proteins out toward the membrane where they are then expressed to perform their various functions.</span><span />
