Investigating how light intensity will affect the rate of photosynthesis, with the help of DCPIP, in Spinach leaves.

The aim of this experiment is to find out how the rate of change of light intensity affect the photosynthesis in spinach leaves.
Successful farming of food crops is very essential for both the nutritional and financial health of a nation. Governments of almost every nation invest land and labour to crop farming, as much as is possible, keeping in mind the other needs of a country. But, however, due to many reasons the maximum crop yield possible is not always achieved.
For the production of a healthy crop certain conditions are necessary. The primary among these conditions are ...

I. Introduction
Advances in recombinant DNA technology and bioinformatics-based data analysis have driven the explosion of structural biology in the last two decades (Kelly, Jess, and Price 119). This has resulted to the identification of at least 2000 proteins annually and a growing need in performing structural studies in these new proteins. The current trend involves the concern of analyzing protein structures close to its natural conditions (and other conditions) and of measuring their rates of structural changes, an essential factor in their biological functions. The technique of circular dichroism (CD) has gained an increasing popularity in addressing these ...

Abstract

Oxidation is a common problem in olive oil due to its high content of unsaturated fatty acid, this leads to nutritional losses and quality degradation, especially under microwave heating. A number of studies have been done to add natural antioxidants to reduce oxidation. This project examines the possible application of olive leaves to reduce or inhibit olive oil oxidation under microwave heating. Olive leaves were able to increase the total polyphenol content as well as reducing the peroxide value in olive oil. However, the microwave heating caused severe quality degradation (increasing peroxide value and reducing total polyphenol) especially after 10 ...

The purpose of this experiment was two-fold. Firstly it was to synthesize shape-controllable Copper Oxide (Cu2O) under alkaline conditions by using hydrothermal methodology. Secondly it was to measure and evaluate its application for photocatalytic degradation of direct blue dye 53 also commonly known as Direct Blue 53 or Evans Blue. Materials used for the first step were Cu2O and the two reactants, CuCl2.2H2O and NaOH. The temperature during the hydrothermal process was raised from 80°C to 140°C. Two products were synthesized: a) the Cu2O nanorod and b) a mixture of Cu2O nanorod and Cu2O nanocubes.

Hydrothermal temperature was found to ...

Abstract

Enzymes are the large biological molecules that play the role of metabolic processes responsible for maintaining the human life. They have the ability of high selectivity, as natural catalysts. They accelerate both the specifity and rate of metabolic processes, from food digestion and DNA synthesis. Most scientific enzymes are proteins in nature, even though some RNA molecules which are catalytic have been studied. The structures of enzymes normally adopt a three dimensional structure, and in order to assists in catalysis, it may employ the organic and inorganic forms. This experiment is meant to describe the properties and characteristics of enzymes ...

Abstract

This research paper will discuss the significant contribution of DNA fingerprinting in the criminal justice system for being able to provide a reliable basis for conviction. DNA fingerprint analysis is referred as an accurate indicator to determine the guilt and innocence of an accused. The history, importance and various DNA fingerprinting techniques shall be discussed. In addition, DNA fingerprinting is considered as more superior than other forensic science methods since the technology has improved over time. DNA fingerprinting has allowed the test of smaller amounts of material, faster testing procedures and more conclusive results. Finger ridge analysis is science and ...
