CHAPTER ONE 1.0 INTRODUCTION Flooding is one of the major environmental crises one has to contend of within the century. This is especially the case in most wetlands of the world. The reason of this is the general rise in sea level globally‚ due to global warming as well as the saturated nature of the wetlands in the Niger Delta. Periodic floods occur on many rivers‚ forming a surrounding region known as flood plain. Rivers overflow for reasons like excess rainfall. The good thing

Experiment 3: Soil pH measurement Introduction Aims The aims of the experiment were to determine the pH of a variety of soils which included sedentary‚ 3:2‚ sand‚ organic matter with the means of a pH meter at various soil water ratios and with or without calcium chloride. Method and Materials Samples of sedentary soil‚ 3:2 soil‚ sand‚ organic matter and compost‚ 100ml vials(x12)‚ bottle of distilled water‚ analytical balance‚ pH meter‚ 2 buffer solution of known pH‚ 0.25M calcium chloride

Red Cabbage Indicator Aim – To create a pH indicator out of a red cabbage solution and to construct a basic pH scale to determine the pH of unknown solutions. Materials - • red cabbage leaves • 250 mL beaker • hotplate or Bunsen burner‚ tripod‚ gauze mat and bench mat • 10 test-tubes – equal size • test-tube rack Methods - Part A: Making the indicator 1. Tear up one or two red cabbage leaves‚ and place them in the beaker with enough water so that the cabbage is just covered. 2. Heat the beaker

Does peaceful resistance to laws positively or negatively impact a free society? I believe that peaceful resistance has a positive effect on a free society. When someone is peaceful no harm is done to anyone nor to one’s own because there is nothing bad done from the person seen as disrespectful. A free society is only negatively affected by peaceful resistance when one side of a story is unpeaceful. In which case all the incidents recalled from this year‚ for example‚ would be the protestors

SLII The effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water

The effects of the corrective strategies which shall be deployed vis-àvis these 12 students shall also be observed. To this extent‚ the research unfolds within a phenomenological framework. The research‚ however‚ is not restricted to the phenomenological approach

more harm than good. Discuss both points of view. Many surveys and researches indicate that modern medicine has many benefits. In contrast‚ others argue that it causes more harm for human healthy life. This essay examines both positive and negative effects of Western medicine. There are some logical reasons proving that modern medicine provides more advantages for humans. Their treatment is based on high technological science‚ and then they do experiments on animals before applying on human bodies

How to overcome individual-level resistance to organizational changes Abstract Organization change is prevalent‚ we cannot avoid failure in working‚ it is just the question about sooner or later. When we met frustration‚we have to take steps to alter the environment.Thus‚ change in organization is a necessary result of standstill. However‚ where there is change‚ there is resistance to change. Lectures show that resistance of employees is always the largest barrier for the organization

Self-design Practical: The effect of pH on enzyme activity Rationale Amylase is an enzyme involved in the digestion system which catalyses the breakdown of starch into sugars. It is not only present in human saliva but also in the pancreas‚ where it hydrolyses dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. pH has an effect on the activity of all enzymes‚ including amylase. As the pH level increases‚ the enzyme
