Joshua Annan Biology Section-04 Diffusion and Osmosis December 14‚2012 Alexis‚ Adiba‚ Elliot and Joey Purpose: The purpose of this lab is to get a better understanding of osmosis and diffusion in molecules. We will do this by studying different solutions and how they move through the permeable membrane. Hypothesis: The three different possible predictions were the lab were that the mass would stay the same‚ the mass will increase‚ or the mass will decrease

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise

Osmosis and Diffusion During the past few weeks in my Ag Biology class we have been learning about and reviewing both osmosis and diffusion. We did two different labs‚ one on osmosis; the other on diffusion. The first lab we did was our diffusion lab. We learned that diffusion is moving something from an area of high concentration to a low concentration. We were showed that Mio and other flavor drops perform diffusion when put in water as an example. For the lab part we put a mixture of starch

Science Research Paper: “Potato Battery” I. Problem a. Main Problem This study aims to prove whether fruits and vegetables are good reserves of electricity. The potato‚ known for its high Phosphoric Acid and Sulfuric Acid‚ has been as our chosen fruit to prove and conduct our answers upon the accessibility of fruits and vegetables as an effective renewable energy source. b. Sub-Problems To further provide extra and specific information‚ the researchers have decided to add the following

Group 2 Science Investigatory Project I Title: Potato Battery II Objective: We only need a potato‚ a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails

The History of the Potato Chip One of the most recognizable snack foods is the potato chip. Who can resist this thin slice of potato‚ fried into a crisp then salted? Potato chips are delicious and very popular. They satisfy the taste buds of many by hitting all the essential characteristics of a good treat. They are convenient‚ easily found‚ salty‚ greasy‚ and come in a wide variety of flavors. It is hard to believe their invention was a mistake. When George Crum‚ a Native American chef in Saratoga

Polypeptides‚ better known as proteins‚ carry out nearly all of a cell’s functions. A protein is made up of at least one or more amino acid polymers. The necessity of proteins for life is unequivocal‚ not only do they help to form the structures of cells but they act as enzymes in reactions of the body1. Enzymes are biological catalysts that lower the amount of activation energy needed in carrying out biochemical reactions1. Enzymes are responsible for almost every reaction that occurs in a cell

POTATO INTO BATTERY Abstract a.Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode. c. Result It did go well and the potato did give voltage to the equipment (clock) However‚ the

liver and potato. They provide a site where reactants can be brought together to react. These reactants are called substrates that fin into the enzyme. The changing of heat‚ surface area‚ chemicals‚ and pH will denature the shape of the enzyme‚ not allowing it to do its function. Testing on peroxidase- an enzyme- will be done on an animal enzyme (chicken liver) and a plant enzyme (potato). For testing Hydrogen Peroxide (H2O2) will be poured over the enzymes. When the enzymes in the potato or liver

When the peroxide was added to the potato and steak extract‚ 0 mm of foam layer was formed. And when peroxide was added to the liver extract‚ it created the most foam layer thickness which was 68 mm of foam. When temperature and foam thickness were determined‚ the results indicated 0 mm of
