The ginger root is from the plant zingiber officonate. It is from the same plant family as tumeric‚ a commonly used cooking spice. It has many uses in cooking and homeopathic medicine. Ginger root is grown in warmer climates‚ and used in landscaping as well as harvested in bulk. Ginger root is an herb. Ginger root is also known as several other names including amomum zingiber‚ ardraka‚ cochin ginger‚ gingembre‚ gan-jiang‚ sheng-jiang‚ and black ginger. First cultivated in South Asia and

Understanding ion permeability is vital to knowing how it establishes a membrane potential‚ and how it eventually leads to the contraction of muscle cells. This was done using crayfish tail muscles. Lateral and medial tail muscles from the tail of a crayfish were excised. These muscles were then placed into solutions with different types of ion concentrations. Usage of different ion concentrations was necessary in practicing how to measure resting membrane potentials accurately. Measurements with

Damage of Beet Cell Membranes Caused by Different Temperatures Resulting in Betacyanin Leakage By: Trevor Sandum‚ Lab 2‚ March 9‚ 2013 Introduction: A red pigment called Betacyanin located in the vacuole of the beet cells is released when the membrane is damaged (Danyk‚ 2013). The membrane is necessary for sustainability of the cell’s life‚ it separates the cell from the outside environment‚ and is responsible for diffusion‚ exocytosis and endocytosis‚ and transport. It

Investigating the Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents‚ for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must

1.0 Summary This experiment is conducted to determine the liquid permeability of porous media. The apparatus used in the experiment is the liquid permeameter. The liquid used in this experiment is water. Three membrane samples of different thickness (0.1‚ 0.2‚ 0.3 cm) are used as the porous media. The determination of the permeability is carried out using elevated pressure test. Each sample is tested for 5 times at different values of pressure gradient which are 5‚ 10‚ 15‚ 20 and 30 psi. In order

Introduction In the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them) because they

Root of Greed Money is the fuel‚ the pursuits to the things we need like food‚ education‚ medicine‚ and our well-being. We as human beings want and desire those things which are far from our grips‚ but are only attainable with the exchange of money. In this case acquiring items like guns and other goods‚ the exchange is not of money‚ but humans. People do imaginable things to acquire it by lying‚ stealing‚ and even murder.
