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

Journal #4 I am reading “To Kill a Mockingbird” by Harper Lee and I am on page 304. So far this part of the book is the trial of Tom Robinson.

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

pleasant‚ fruit-like odors and are the chemicals responsible for the odors and flavors of many fruits (oranges‚ bananas‚ pineapples) and flowers. In most cases‚ such natural products get their properties from a mixture of organic compounds. In this experiment you will prepare two esters of o-hydroxybenzoic acid‚ more commonly known as salicylic acid. One of the esters‚ acetylsalicylic acid‚ is aspirin‚ the common analgesic. We will synthesize aspirin by mixing salicylic acid with acetic anhydride. The

Jackie Kennedy presented a new convention of glamor and appeal to the First Lady lifestyle. Jackie’s elegant style aided her refurbishment of the White House public rooms.

On the 30th of December‚ 2016‚ I watched the TED talk of Ken Robinson‚ british author and public speaker. He explains his view on the role of creativity in children‚ providing his opinion that creativity is just as important in education as literacy‚ and that you grow out of creativity‚ not into it. Specifically he claimed that education eradicates creativity. As he said‚ “I believe this passionately‚ that we don’t grow out into creativity‚ we grow out of it. Or rather‚ we get educated out of it

Would you put an innocent man in jail? Back in the 1960’s if you were black it didn’t matter. This is why Harper Lee’s novel To Kill A Mocking Bird exaggerates that Tom Robinson is not guilty but convicted for his color. Also Harper lee expresses that the jury is flawed clearly. Being convicted causes Tom to lose his innocents literally. This is the theme that Harper Lee is trying to get across. While Tom loses his innocence so does Jem Finch mentally. Jem thinking that justice will always be served

- 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)
