individually incubated at temperatures of 5‚ 25‚ 37‚ 45 and 55°C for one week in an aim to distinguish the effect temperature has on growth and survival of the five different species. After one week they were observed for distinguishable changes by the turbidity showing an indication of bacterial growth‚ or the clarity an indication of no survival. The second part of the experiment was to examine the effect temperature had on the survival ability of the five bacteria mentioned above. One of the five bacterial

Water samples were also taken‚ and were tested for‚ conductivity‚ PH levels and Turbidity.

because of the failure to count and record the number of viable cells after a 24-hour incubation period. The measurement of absorbance may be used to analyze bacterial growth since the absorbance or the measure of the turbidity is directly proportional to the number of cells. Turbidity results from the deflection of light by bacterial cells present‚ thus‚ the more turbid the broth is‚ the more bacterial cells are present and the higher the absorbance reading is. There are four characteristic

Causes and mechanisms of water resources degradation Logging of forest Logging is the cutting‚ skidding‚ on-site processing‚ and loading of trees or logs onto trucks. Logging and the subsequent denudation of the forest cover increases surface runoff since there is less oppurtunity for rainwater to sink into the ground. .Retarded or supressed infiltration accelerates overland flow production‚hastening delivery of rainwater into streams and rivers‚ the oftentimes the water ends up as floodwater

for things to grow. The second test was testing the hardness‚ nitrates and nitrites‚ and the pH level of the creek. Reasons why we test this is because only certain levels of pH support life and water hardness and nitrates also affects growth. Turbidity test is where you fill a tube and measure how many inches till you can see the bottom of the tube. This test shows how dirty or clean the water is and how visible the water is. The last test was for dissolved oxygen within the creek and this one

EFFECTIVENESS OF BASIL ( Ocimum Basilicum Lamiaceace ) PLANT FOR URINARY TRACT INFECTION INTRODUCTION Background of the Study The care of Urinary Tract Infection (UTI) is a common costly problem in acute care and home care population. Many therapies have been made for the treatment. Despite this‚ the patient still suffer from pains when urinating and the financial burden. In the locality‚ Urinary Tract Infection was commonly experienced among teenagers due to lifestyle and diet. Nurses in the community

ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without
