It was hypothesized that if the animal was larger‚ then it would have larger hemoglobin. It was thought that larger mammals would need more oxygen-rich hemoglobin to support healthy function. This lab did not support this hypothesis. The results in table 1 displayed that the hemoglobin of all mammalian samples traveled about the same distance. This trend can be seen in graph 1 as the mammalian hemoglobin samples migrated the same distance. Because the proteins traveled around the same distance it

Scandals have broken in both the 2005 Indonesia food scare and 2007 Vietnam food scare regarding the addition of formaldehyde to foods to extend shelf life. After a four-year absence‚ in 2011 Indonesian authorities have again found some foods with formaldehyde being sold in markets in a number of regions across the country

separation of the two conductors. The dielectric constant of the non-conductor is also affecting the capacitance. FIGURE 1 Capacitor symbol For an ideal capacitor‚ the capacitor current iC is proportional to the time rate of change of the voltage across the capacitor: Where C is the proportionality constant and is known as capacitance. (b) Inductor Inductor is an electrical passive device for storing energy in the form of magnetic field. In its simplest from‚ It consists basically consists

Microbiology Osmosis Lab Report Lab Experiment 9 Osmosis Introduction Kinetic energy is present in cells and its this energy that causes the cells to move. Diffusion causes cells to move from a higher concentration to a lower concentration. Osmosis is a diffusion that allows movement of water through a selectively permeable membrane. Osmosis occurs until it reaches equilibrium‚ or when the concentration on each side is the same. This is called an isotonic solution. A solution with differing

A. Avril Crayfish Lab Report November 9‚ 2012 Dr. Marvin Results: Figure 1. Firing Rate of Tonic Receptor in Response to Stretch. The correlation between Firing Rate and Stretch of the slow adapting crayfish receptor for four different sets of data is represented in this figure. The recordings are taken at stretches of 2‚ 4‚ 6‚ 8‚ and 10 mm of the crayfish tail. The best fit lines for the different sets of data are as follows: Ali and Emily- Linear best fit line‚ Dave and Laura- Exponential

by using the application of membrane have become highly demand in various industries. In this newly separation process ‚ the membrane function as a semi-permeable barrier and the separation process occur by the membrane controlling the rate of movement of various molecules between two liquid phases ‚ two gas phases or a mixture of a gas phase and liquid phase. In industries‚ many companies have high demand on both quality and quantity of water for production. Membrane process can be used to separate

Practical 2.1- The Effect of Temperature on Membranes Objective To investigate the effect of temperature on membrane structure Introduction Beetroot Pigments Beetroots contain Betalains which are the red pigments present in the cell vacuole. Betalains are soluble in water and they contain nitrogen. Betalains extracted from beetroot is commonly used as food dye because it is not known to cause any allergic reactions.

between‚ necessary units called cells are constantly keeping your body in a living condition. Robert Hooke is who identified and named cells. “He thought that the small ‚ simple units looked like the bare prison cells. His work launched a new frontier in scientific exploration that led to modern cell theory; all living things are made of cells‚ cells are the basic units of structure and function in all living things‚ and all cells come from the reproduction of existing cells.” (Moulton‚ 2004).
