In "The Birth-Mark" by Nathaniel Hawthorne‚ the author floods the story with many forms of symbolism to show there is no true form of perfection on earth. Although trying to accomplish such a thing‚ Aylmer not only highlights his failures as a scientist‚ but also kills his beautiful wife. After many nights of gazing upon his wife’s porcelain face‚ slaying her heart with his disgusted looks‚ Aylmer convinces his wife Georgiana to let him conduct an experiment on the hand-shaped‚ rosy birthmark she

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

Photosynthesis Experiment Introduction Photosynthesis is a process used by plants‚ making inorganic molecules into organic molecules (food) using sunlight. Carbon dioxide + Water (mainly from rain) Glucose + Oxygen From this process‚ carbon dioxide comes from environment. Glucose‚ as a product is used to make energy for growth. Lastly‚ the oxygen is a waste product in this chemical reaction‚ which become part of the Earth’s atmosphere. At this experiment‚ carbon dioxide and water

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

Controlling Nature: A Losing Battle In the story “The Birthmark” by Nathaniel Hawthorne‚ science versus nature is an essential source of conflict. This theme becomes apparent through Alymer’s persistent desire to interfere with what is natural through his passion for science. This obsession becomes most apparent when Alymer attempts to change his wife Georgiana’s natural appearance. Soon after marrying her‚ Alymer is shocked by the smallest of imperfection‚ and expresses desire to remove it‚ as

“The Birth-mark” is a short story by Nathaniel Hawthorne. Hawthorne begins his story by introducing his main character Aylmer‚ who is a “man of science.” Aylmer leaves his laboratory to marry a woman‚ Georgiana‚ whom he fell in love with. The couple then marries. Aylmer begins to notice a birthmark in the center of Georgiana’s left cheek. The birthmark‚ according to Aylmer‚ is an imperfection. The birthmark is in the shape of a human hand‚ and is a rosy color. Georgiana has always liked her birthmark

The graph should show an increase in arbitrary units the further away from the light source the beaker is because the greater the distance from the light source‚ the lower the light intensity and so less photosynthesis

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in
