If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH

Primitive‚ and the Perceptual Lens To say that any culture‚ region‚ or country is civilized or primitive is purely subjective to the person stating the opinion. Each individual‚ whether educated or uneducated‚ will have a different view on the definition of those two terms; a view that is influenced by the perceptual lens‚ or bias‚ that the individual has developed through various experiences over their lifetime. Nonetheless‚ how do subjectivity and the perceptual lens manipulate the

Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

Assignment 1 Perceptual Biases and Reducing Their Impact May 29‚ 2011 Biases‚ and more specifically‚ perceptual biases are a range of humanly inevitable techniques that are used by people to make sense of the behaviours‚ personalities‚ and attitudes of other people around them. These various techniques are generally the easy way out when we try to analyze an individual’s predisposition. However‚ because they are the easy way out‚ they cause us to receive only a limited and possibly inaccurate

In the early 1800s life in Ireland wasn’t easy‚ Irish citizens got by day to day by farming and relying on the potato. The potato was their main source of food and money. With out the potato the Irish would have nothing. No one was prepared for what was about to happen in 1845‚ the beginning of the Great Irish Potato Famine. The Irish Potato Famine was the worst tragedy in the history of Ireland. The outcome of the famine would result in hundreds of thousands dead‚ an failure of the economy

When presented with a situation one generally airs on the side of caution and chooses an answer or action that will make them fit in even though it is not their true opinion. The author introduces a specific type of conformity called perceptual conformism. Perceptual conformism

Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

There are four stages in the perceptual process: information attention and selection‚ organization of information‚ information interpretation‚ and information retrieval. Information attention and selection involves the screening of the vast amount of information bombarding a person to determine the information on which he/she will actually focus. Organization of information involves the use of schemas –– person‚ script‚ and person-in-situation –– to efficiently organize the information that is perceived

This was conducted through four different experiments. The first tested the effect of temperature on enzyme activity. The independent variable in the first experiment was the temperature of the solution of pH 7 buffer‚ potato juice‚ and the enzyme. The independent variable for the second experiment was the pH of the phosphate buffer. The independent variable for the third experiment was the enzyme concentration of the solution‚ and finally the independent variable of the
