the phospholipid bilayer:
1. allows certain substances in and out of the cell
2. allows the water in the cell to stay in and the water outside to stay out.
Answer: The means for transmission of disease-causing microorganism is provided by the direct or indirect contact.
Microorganisms can cause disease only once they are transferred to the body. The disease causing microorganisms are termed as pathogens which are transmitted by several ways such as from skin to skin, by nuclei droplets, through blood and body fluids or via air. In vector transmissions the disease is carried by the parasitic insects via animals, air borne transmission occurs when microorganisms move through air or the dust particles, droplet transmission occurs by coughing, sneezing or talking by the person who is infected while indirect transmission occurs by physical contact or by touching contaminated objects.

An alternative approach to this experiment would be the use of Spectroscopy. Instead of trying to visualize and guess the fraction with the most intense color, the exact fraction could be found with Spectroscopy. A range of fractions that are the most intense are measured with the absorbance value for each one. The fraction with the highest absorbance value will be the most intense fraction.This method guarantees that the <span>correct retention volume is recorded.</span>
