ionic‚ polar or covalent will dissolve in it‚ therefore more reactions take place while in solution with water. Often in organisms substances must be in solution and water is the solvent. Plants can only obtain mineral salts in solution and human digestion will only dissolve soluble foods‚ meaning large starch molecules must be broken down into soluble sugars. Also many organisms living in water spend most of their time underwater‚ yet they require oxygen to respire‚ and as water is such a good solvent

GMOs are genetically modified organisms that are usually put in crops to make them bigger‚ tastier‚ or healthier. Though this sounds like a great idea there are extreme drawbacks. For instance GMOs are already increasing herbicide use in the U.S. by 26 percent since 1998 when the leaders of GMOs said that they would decrease herbicide use. This also means that more weeds are becoming resistant to herbicides and so GMOs are creating superweeds that are even harder to kill. With the constant spraying

PTLLS – Assignment 3 Analyse different ways in which you would establish ground rules with your learners‚ which underpin behaviour and respect for others. Within my area of teaching in counselling‚ establishing ground rules early on helps avoid group disruption. Gravells (2008:7) states ‘Without ground rules‚ disruption may occur and affect the learning of your group.’ There are many different types of ground rules that can assist in creating mutual respect from tutor to students and vice a

feedback in living organisms Negative feedback is a principle which is used by the body in order to return systems to its normal level; it does this by turning the corrective measures off. Homeostasis uses the principle of negative feedback in order to maintain a constant internal environment. There are a number of different examples of negative feedback such as thermoregulation‚ regulation of blood glucose and the regulation of water potential. The control of the heartbeat can also use negative feedback

Alvarez somehow reminds me the process of studying English. Unlike the author‚ I was born and grew up in a place far from the United States‚ Vietnam. Generally‚ English is our second language. Yet‚ the way we achieve it consisted of both similarities and differences. First of all‚ Vietnamese and Spanish use the same Latin alphabet that English does. However‚ in Vietnamese some special marks were added to make new characters. Some of my American friends thought it was easy for me to learn English because

#2) Both Winner and Joy explore the issue of technology and control. How would you compare their two views of current technological development? Focus the comparison on a specific technology‚ such as genetically modified organisms. Technology is always in need of control. You cannot have a world that technology is in control such as the movie Terminator‚ where technology takes over. Just like human beings there is always a need for control. Both Winner and Joy explore this topic; Joy believes

Managing and leading are two different ways of organizing people. The manager uses a formal‚ rational method whilst the leader uses passion and stirs emotions. William Wallace is one excellent example of a brilliant leader but could never be thought of as the manager of the Scots! Managers think incrementally‚ whilst leaders think radically. "Managers do things right‚ while leaders do the right thing." . This means that managers do things by the book and follow company policy‚ while leads follow

Energy Systems The ATP – CP system is primarily used for short duration exercises (about ten to twelve seconds) which involve a high intensity or explosive movements. Energy is stored within the chemical bonds between the Adenosine and the three phosphate molecules. Water is added in the chemical reaction‚ causing one of the bonds to break‚ which releases one molecule of energy from the phosphate. This molecule is used for the muscle contraction. The ATP then turns into ADP as it’s lost a phosphate

Discuss the Role of Hydrogen Bonding in living Organisms A hydrogen bond is an intermolecular bond and is formed when a charged part of a molecule having polar covalent bonds‚ forms an electrostatic attraction with a molecule of opposite charge‚ generally with fluorine‚ oxygen and nitrogen. Molecules having non polar covalent bonds do not form hydrogen bonds. Hydrogen bonds are classified as weak bonds as they are easily and rapidly formed and broken‚ however the cumulative effects of large
