Osmosis and Diffusion

The basic principles of Osmosis and Diffusion were tested and examined in this lab. We examined the percent increase of mass and molarity of different concentrations of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion, and in a biological context, we can simulate how water and particles move in and out of our own cells. Introduction Objective: 1.

Germs: Bacteria, Viruses, Fungi, and Protozoa

A virus is a small infectious agent that replicates only inside the living cells of other organisms. Viruses can infect all types of life forms, from animals and plants to bacteria and archaea.

This in turn can produce unnatural behavior and results that do not generalize to real life. This can be seen in experiment 2 when 12% of the control group reported seeing broken glass even though they were unaffected by the verb. This could be attributed to the leading question or to…...
