1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer

Lab 2.1 – Identify Business Rules‚ Attributes‚ and Candidate Keys Step2 Are your patient records in a computer system already? How is patient info followed and updated? How do you process your reports? How do you separate the dropped patients from the ones still in the program? Do you classify patients by their health status? Step 3 Business Rules: The doctor must login to database and select patient’s records that he/she is seeing for that day. Front Office workers are able to view medical history
