Thyroid Gland Pituitary Gland
1,366 wordsAccording to the American Thyroid Association, millions of Americans (especially women) suffer from a thyroid disorder, and many of them dont even know it. In fact, thyroid disorders occur much more often than even many doctors realize. The butterfly-shaped thyroid is in the neck, its two wings wrapped around the windpipe just below the Adams apple. This vitally important gland normally weighs less than an ounce, but it can have an enormous impact on your health. Think of it as your bodys metabo...

Thus the eyes develop a staring quality and they may tend to bulge outwards (Korte 1994). This appearance is due to changes in the nervous control of the upper eyelid and usually disappears as the hyperthyroidism is controlled (Epps 1995). These changes may occur in hyperthyroidism due to any cause, and is not specific to Graves disease (Foley 1993). There are three main methods in treating hyp...

Hydrogen Peroxide Wastewater Treatment
965 wordsThere are many reasons why we need to treat our water, and there are also many different ways we can treat our water. Water is very important to our survival. Regulations are set so that our water is healthy for us to drink. Without those regulations there could be things in our water to cause us to be sick. Some problems in parts of the country are heavy metals. One of the best ways to see if you have heavy metals in your water is to have a lab test your water. Turbidity can also be a problem. ...

Permeable Membrane Semi Permeable
781 wordsOsmosis is the flow of water through a semi permeable membrane that blocks the transport of salts or other solutes through it. It is also defined as the net movement of water from an area of high concentration to a region of low concentration. Osmosis is a fundamental effect in all biological systems. When two water volumes are separated by a semi permeable membrane water will flow from the side of low solute concentration to the side of high solute concentration. If external pressure is applied...

Gram Positive And Negative Bacteria
828 wordsGram Positive and Gram Negative Bacteria It is a well-known fact that bacterial cells, like plant cells, are surrounded by a cell wall. However, few people know that their cell walls are quite different. Bacterial cell walls are made up of polysaccharide chains linked to amino acids. At the same time, plant cell walls are made up of cellulose, which contains no amino acids. In the same way, bacterial cell walls themselves differ from one another. Scientists distinguish two types of bacteria cell...

These are the most abundant elements in living organisms. These elements are held together by covalent bonds, ionic bonds, hydrogen bonds, and disulfide bonds. Covalent bonds are especially strong, thus, are present in monomers, the building blocks of life. These monomers combine to make polymers, which is a long chain of monomers strung together.

Rate Of Reaction Bunsen Burner
2,301 wordsFor this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...
