Osmosis Essay

Plants require certain substances that are necessary for their survival. These requirements are carbon dioxide, water and mineral nutrients. Mineral nutrients are essential chemical element that are critical for plants to sustain life function and complete their life cycle (Uchida, 2000). These nutrients are classified into two groups micro a macro nutrients. Micronutrients are elements are used in very small amount these include boron, chlorine, cooper, iron, manganese and zinc. While…

Like any other engineering disciple, chemical engineers are deeply interested in bettering the world through innovation. They seek translate their knowledge in mathematics, science, economics and even social insight into actions, and aim to invent, design and construct new perspectives and concepts to tackle the problems we face in the world today. Many tend to associate the term ‘chemical engineer’ with huge process plants and chemical reactors. Whilst this is not an inaccurate reflection of a…

Introduction The kidney has an important role in the body. It regulates water and salt volume, and plasma pH of the body. The body helps maintain the balance of salt and water in the blood. This is done by three processes which are glomerular filtration, tubular reabsorption, and tubular secretion. The balancing of the pH is also as important for the human body. If the pH is well maintained and balance, it shows that the kidney is working properly in the body. Following…

The plasma membrane also known as the cell membrane is found in every cell. The cell membrane is around 7-10nm, making it difficult to view even with a transmission scanning electron microscope (it only shows a double black line), this means that no one knows exactly what the membrane looks like. All membranes have the same basic structure made up from phospholipids (fats). The membrane is made up of a phospholipid bilayer; consisting of a polar phosphate head and two fatty acid tails. The head…

Elizabeth Casey Lab Partners: Cara Hull, Erin Magennis, Claire Pfeffer Bio2300 Section 1 10/6/16 Dr. Henle Testing Effects of Glucose and Sodium Chloride on E.coli Cell Division Hypothesis: We hypothesized that if E.coli cells are grown in broth containing 1% 1M glucose, then they will divide more rapidly than they would without the glucose additive. Our independent variable was the glucose, and our dependent variable was E.coli cell density. Methods: This procedure was obtained from the…

The Consequences of Climate Change on Unindustrialized Countries In countries that lack industrialization, agriculture is a prominent economic sector. They provide raw material such as cotton, coffee, and wheat that are exported to more developed countries, which in turn provides consumer product. However, the market of agriculture is solely based on a consistent environment that is favorable for their respective crops. With the impending issue of climate change, the respective sector is most…

To make the play “Happy Valley” newly and currently relevant to a Lingnanian, or even to a Hongkongese, I would like to reset the last scene of the play in Hong Kong, to where Uncle Chester brings his wife and daughter back and stays at Tuppy’s home. In addition, by setting my new version of this scene on 1st July 2015 (after 18 years of the handover), I can highlight the persistence but also the loss of the Hongkongers, who are compelled to accept their citizenship without choice and any…

collecting ducts. The collecting ducts will transport urine back through the concentration gradient and back through the nephron loop. The walls of the collecting duct are permeable to water, not sodium. Through osmosis more water is drawn out. ADH determines the the permeability of the collecting ducts resulting in less urine secretion and more concentration. Less ADH results in less concentration of urine and more volume. Micturition, meaning urination. Once urine is produces as stated above…

Water is one of the most important complex and necessary molecules on earth. It is required for any organism 's survival and is vital for life processes. Its molecular structure enables it to have a chief advantage over other molecules. Its polarity and attraction to other types of matter enable water to be a perfect solvent used with detergent and soap. The range of water is expensive, available on earth as three different types. Despite the abundance of these molecules, many countries continue…

Right now, developing countries barely have water access. With the access to clean water; education, health, hunger, and poverty rates within every community will improve tremendously. In developing countries, children miss days and days at a time away from school because they spend most of their day searching for water or they have become ill from water-borne disease. With access to clean water, children can spend more time in the classroom than outside searching for water miles away from their…
