obesity percentages. Sucrose is the leading added sweetener in in the manufacture of foods in the Unites States and is the biggest source of fructose. Sucrose and high fructose corn syrup (HFCS) are metabolized identically and react the same way to insulin‚ leptin and ghrelin. Sucrose is indifferent from HFCS in causing obesity. Compared to glucose‚ sucrose is extracted directly from the liver while glucose goes directly to the bloodstream causing larger sugar spikes. HFCS and sucrose have an identical

After the seven days of quantitative and qualitative data collection‚ the results showed that the substances individually had a significant effect on their respective plant. Furthermore‚ the original hypothesis was shown to be accurate regarding the sucrose and caffeine receiving plants‚ and inaccurate in the case of the plant receiving carbonated water. To begin with‚ it is important to note the control plant experienced unusual results‚ as the plant had a sharp decrease in the quantity of blooms. However

The purpose of the egg crash is to design‚ build‚ test‚ and evaluate a landing pad to protect an egg from the collision of a hard surface falling from various heights. An individual should be able to describe the collision in terms of changing momentum‚ impulse‚ impact force‚ and impact time. All moving objects have a quantity of motion‚ otherwise known as momentum. Momentum of a moving object can be found by multiplying the mass of the object by the velocity. Because mass is measured in kilograms

AP Biology August 23‚ 2012 Egg Osmosis Lab Definition of osmosis: The diffusion of water across a selectively permeable membrane from high to low concentrations Hypothesis: If I place an egg in vinegar‚ then the outer layer of the egg is going to become slimy and look like rubber. It will also become larger and bubbles will form on and around the egg. Hypothesis: If I place an egg in corn syrup‚ then the egg will become small and the outer layer will not look like rubber any longer. Day one:

goal of winning the egg drop competition‚ our team had a more specific goal. That was to create a device that would not make any eggs crack. The problem‚ then‚ was to design a device with maximal padding to keep the eggs safe. We wanted to create something that even if one safety feature failed‚ others would kick in. Therefore‚ we were inclined to experiment with many different packing materials and bubble wrap types. We started out with three tupperware containers and three eggs. In each container

Biology Investigation: Effect of different concentrations of sucrose solutions on the mass of potatoes Research question Is the mass of potatoes going to be smaller or bigger in different sucrose concentration? Introduction Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

Shell - less egg is placed into a beaker of corn syrup‚ will there be any water going into or out of the egg and if the shell - less egg is placed in a beaker of distilled water will be any net flow of water going into or out of the egg. Hypothesis: If a shell - less egg is placed into a beaker of corn syrup solution‚ then there will be a net flow of water going into the egg because the water molecules will be small enough to pass through the membrane of the egg. If a shell - less egg is placed

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

Victoria Pham Marshall Malino Ethan Waugh Naked Egg Drop lab May 21‚ 2013 The purpose of the lab was to create a contraption that prevents an egg from breaking when dropped from about 18 ft. We made net out of yarn and lined the bottom of the box with cotton to soften the impact of the egg. Though the contraption didn’t work very well since the egg broke the moment it landed. Though we managed to calculate the amount of Potential energy at the start and how much kinetic energy it had when it
