The kidneys secret renin‚ which activates the angiotensin-aldosterone pathway. 3. Regulation of the pH of the blood: The kidneys excrete H+ ions (hydrogen atoms that lack their single electron)‚ into urine. At the same time‚ the kidneys also conserve bicarbonate ions

Miscanthus is a perennial‚ rhizomatous‚ giant grass that was originated from East Asia and now distributed worldwide. This subtropical plant has C4 photosynthetic pathway and can be grown in warm seasonal weather. These perennial rhizomatous grasses are promising energy crops due to their high productivity‚ low nutrient requirements‚ ecosystem services and great potential for C mitigation (Lewandowski et al.‚ 2003a;

because there is no reference dose of magnesium stated by the US EPA (2002) and RAIS (2011) as the copper and manganese. Table 3.2 in the Chapter 3 showed the RfD of copper and manganese. The HQ result for the copper and manganese by the soil exposure pathways is in Table 4.11 and 4.12. If HQ equal or less than 1 indicates no adverse human health effects are expected to occur and HQ more than 1 indicates likely adverse health effects to occur.(Man et al.‚ 2010).

INTRODUCTION: Badminton requires a high level of energy to quickly move around the court‚ deliver effective shots and sustain a match. Knowing how this energy is generated is crucial.All other things being equal‚ the player with more stamina will most likely win a match in baminton. This is because while good stroke skills‚ effective shot placements and fast footwork are important characteristics in a good player‚ fitness is necessary in executing and sustaining these movements for the duration of

CHAPTER 4: ENZYMES Enzymes are biological catalysts. There are about 40‚000 different enzymes in human cells‚ each controlling a different chemical reaction. They increase the rate of reactions by a factor of between 106 to 1012 times‚ allowing the chemical reactions that make life possible to take place at normal temperatures. They were discovered in fermenting yeast in 1900 by Buchner‚ and the name enzyme means "in yeast". As well as catalysing all the metabolic reactions of cells (such as respiration

Introduction: Each student was given unknown bacteria and was instructed to perform a variety of experimental tests that would help to identify their bacteria. During the process of identification‚ the unknown bacteria was added to many different testing medias using aseptic technique. They are as follows: lactose fermentation on eosin methylene blue (EMB)‚ TSI (Triple Sugar Iron agar)‚ Phenol

The metabolic response to prolonged starvation Early stage of prolonged starvation Starvation occurs when the body has a severe lack of nutrients needed to survive. The body has ways of adapting to periods without food‚ for example overnight it needs to survive without any additional nutrients whilst asleep. The body however also has ways of adapting for as long as long as 5-6 weeks (Garber‚ 1974). Therefore‚ looking at the metabolic state during starvation is over a long time period. The body

Biology‚ is the study of living things. In biology there are many branches that all contribute to life. Those branches of life aid each other’s function to maintain their function. In photosynthesis and aerobic cellular respiration energy is being produced to cycle carbon between the functions. There is the function of maintaining life‚ helping aid chemical reactions‚ using the cell to help aid reation. All of these recycling processes help creates energy that is then in return used to aid their
