The concentration level of heavy metals (Pb, As, Cu and Fe) were assessed in five boreholes waters from Ikono Urban. Atomic Absorption Spectrometer was used to analyze the water samples. The results showed that Pb ranged from 0.15±0.040 – 0.40±0.094 mg/L; As, 0.05±0.008-0.10±0.041 mg/L; Cu,...
This paper presents the electrochromic (EC) characteristics of nickel oxide (NiO) nanoflakes array prepared by chemical bath deposition (CBD) method with different ammonia concentration. Prepared NiO films have porous structure with 2-dimensionally networked nanoflake arrays. The addition of aqueous ammonia significantly affects the growth of...
Introduction Biology may be a scientific study of life within which we examine the essential components to living things and their key habits to survival. to grasp this process, we first have a look at the organism’s cell. The cell was discovered and derived because...
Abstract The purpose of this experiment was to determine the concentration of glucose in an assortment of drinks – Coke, Gatorade, and a sucrose solution. This was achieved through the use of a spectrophotometer to measure the absorbance of NADPH, which is directly linked to...
Abstract The purpose of this experiment was to investigate the glucose concentration in popular drinks coke and Gatorade and to identify how a changing environment can impact the hydrolysis of sucrose. This was examined by a series of mutli- enzymatic reactions of glucose resulting in...

Abstract One of the key contributors to the exponentially growing obesity pandemic is the increased consumption of sugar-sweetened beverages such as soft drinks, energy drinks and fruit juices (Malik et al., 2010). In this experiment, a spectrophotometer was used to determine the glucose concentrations of...
Abstract This investigation discusses the relationship between the specific glucose concentration in three solutions Coke, Gatorade and Sucrose. This spectrophotometer was used, this is a device to measure absorbed light intensity as a function of wavelength of 340nm and record visible regions of glucose and...
Rationale In the practical experiment conducted different concentration levels of Tea Tree oil were used against the bacteria of Micrococcus Luteus to measure the effectiveness of Tea Tree oil at different concentrations. The experiment was originally the practical of “Which of the six natural antibiotics...
Rationale The nitrogen cycle (Figure 1.0.1) is complex and involves chemical, geological and biological processes. Flora, fauna and various bacteria are involved. Air is approximately 79% nitrogen but nitrogen gas cannot be used by most living organisms. Instead, plants must obtain their nitrogen from the...
Distractions are frustrating when they get in the way of doing simple or even complicated tasks. Distractions can be auditory or visual and can interrupt activities that are enjoyable or those that require serious attention. In some cases, distractions can be caused by the person...
