Adsorption Experiment This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption‚ absorption and sorption are. Adsorption is the accumulation of gases‚ liquids‚ or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption

The effect of alcohol concentration on the cell membrane Abstract: In this experiment I found out that as the concentration of the alcohol was increased so did the colour intensity of the solution. This is because the higher concentration of ethanol‚ results in more damage done to the cell membrane‚ resulting in leakage of red pigment from the cell. If the membrane is damaged more‚ more red pigment will leak out of the membrane and into the ethanol. Hypothesis: The higher the concentration

of the consequences of excessive drinking. After connecting with her‚ I wanted to know if alcohol concentration in spirits would affect the cells in the body. Thus‚ I decided to test my theory by adapting a class beetroot experiment to my investigation. The aim of this experiment is to investigate the effect of alcohol concentration on a biotic cell membrane. The human body cannot live long with damaged cells because they are the building blocks of life. Cell membranes are phospholipid bilayers meaning

- Quasi Experimental Design: If the researcher lacks control over the assignment of participants to conditions and does not manipulate the causal variable of interest‚ the design is quasi experimental. o Quasi Experiments do not have internal validity because participants are not randomly assigned to conditions and the researcher may have no control over the independent variable. - Basic Confounds in Quasi Experimental Design are : o History o Maturation (Emotional‚ Physical & Psychological)

The Milgram experiment The Milgram experiment came about by a Yale University psychologist by the name of Stanley Milgram. The experiment was to test how well the study participants were and the willingness of study participants to obey an authority figure who instructed them to perform acts that conflicted with what they thought was right. He concluded people obey either out of fear or out of a desire to appear cooperative even when acting against their own better judgment and desires. Stanley
