Potato Chips Jacquelyn opens the yellow bag‚ feeling the smell of the chips engulf her. Then the memories come‚ forcing themselves to the front of her mind. Jackie returns from the kitchen with a bright yellow bag‚ brighter than the morning sun. She grabs the top between her fingers‚ the crackle of the bag alerts Jimmy of what she has. Jackie pulls apart the bag‚ feeling the rush of air towards her face. The smell of cholesterol engulfs her. She reaches in and pulls out one of the golden crisps

The Effect of pH on Enzyme Activity A piece of Solanum tuberosum (potato) was removed and mixed with distilled water in a blender. The resulting solution was filtered through multiple layers of cheese cloth to filter out the liquid by eliminating any large pieces in the solution. The solution created was catechol. Five different solutions were prepared as blanks with each test tube containing 6.0mL of a different pH (pH 4‚ pH6‚ pH7‚ pH8‚ pH10) of phosphate buffer‚ 1.0mL of the enzyme and 1.0mL of

which came from the potato juice. The function of an enzyme is to catalyze reactions in cells. The specific function of the enzyme in this experiment was to see if it affected the activity if it was exposed to different temperatures. A substrate is a material or substance which the enzyme acts. The substrate in our lab was hydrogen peroxide. Procedure For our experiment we used‚ three test tubes‚ nine milliliters of potato

Associated with Battery Disposal: Summary A significant component of our day to day lives is batteries‚ but what many do not know is that the disposal of batteries is actually equally as important. This is a job that is so imperative that‚ if not done correctly‚ can cause excessive harm to the environment and ourselves. The problem does not lie with the batteries per say‚ but the by-products and materials they are made of can become quite dangerous to us and our earth. The number of batteries that are

Seamus Heaney – ‘At a Potato Digging’ • Context • • The poem deals with two different potato harvests. One is the harvest from the present day that goes successfully and which delivers a rich crop. The second potato harvest looks back to the famine of 1845 when the crop failed and many people starved. Whilst the famine is no longer a threat‚ its ongoing fear remains and this can be seen in the use of religious language throughout the poem. For example‚ the bowed heads of the potato pickers suggest the

Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month‚ but if they didn’t have water to drink they will be dead within a week. Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s

Gonen Galor Battery Essay Batteries have proven to be the core of modern day technology‚ without batteries modern day technology and some electronics would have never existed. Nations that invest more in battery run technology tend to have a higher labor productivity rate. This is because battery powered electronics increase could potentially increase the productivity rate of labor and thus an increase in capital goods. Electronics have also been seen as the driving force of emerging economies

potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis‚ by finding the difference in weight before and after the potato has been set in a solution of water‚ sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel‚ potato cutter‚ and test tubes. Then we cut the potato using the
