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

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

Lesson Observation 1 Teacher’s name: Slusari Alexandra Observer’s name: Cebotari Tatiana Topic: Artisanship Date: 10 of April Number of students: 10 Class: VII “B” The lesson I have observed was on the topic “Artisanship”. At the beginning of the lesson the teacher put a clear set of aims to the pupils. She had a lesson plan which helped her to organize the lesson better. She used a lot of additional material. First of all at the beginning she involved pupils into the lesson by asking pupils

One of the life lessons I learned is to always be thankful for the people around me and not take them for granted. Unfortunately‚ many people‚ including myself‚ tend to not appreciate what we have until we lose them entirely. Then later‚ there might come moments in our lives when you miss someone so much that you just want to pick them out from your dream and hug them for real. Only then‚ it’ll be too late to go back. I did not experience these until my grandmother passed away. My grandmother

- 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)
