I. INTRODUCTION Physics, being inherently an experimental science, involves direct observation and physical experimentation. The undergraduate laboratory is thus an essential part of any physics course, developing practical, computational and experimental skills, and certain habits in novice physicists, training them to ‘think like a physicist’ over the course of their degree. The University of Durham … Read more
The purpose of this essay is to explore the topic “A protein found in human breast milk could help kill drug resistant bacteria” through examining a chosen secondary review article, and comparing it with a primary research article. The secondary review article that I have selected is “Lactoferrin: an important host defence against microbial and … Read more
A gene is a segment of DNA which is used for an amino acid sequence which then creates polypeptides. Protein is synthesised through a process in which the DNA is decoded and then the amino acids are then generated from this. This is called gene expression. There are some components needed in order for DNA … Read more

Qualitative research is a fundamental part of understanding our society, it aids in the discovery of social norms, confirms or refutes different hypotheses about society and is a crucial part of the development of knowledge in modern society. Qualitative research is a method among many others of how we describe and explain our social world, … Read more
Phosphofructokinase (PFK) is an enzyme of glycolysis which occurs at a critical point, regulating pathways within the third step of the process. PFK catalyzes the conversion of fructose-6-phosphate (F6P) to fructose-1,6-biphosphate (F1,6BP) by adding a phosphate from ATP, thus creating ADP. The enzyme is sustained allosterically and the △ºG (-14.2 kj/mol) of the reaction is … Read more
Identification of unknown bacteria is a critical part of microbiology. The purpose of the experiment is for students to learn different characteristics of bacteria, construct a proper dichotomous key, carry out tests to differentiate and narrow down bacteria, and use the results to identify two unknown bacteria. By carrying out this experiment, students learn how … Read more
This essay is a draft and may be incomplete in areas. Pandinus imperator (scorpion) Pheretima praepinguis (Earthworm) Chordates (tiger) Earthworm (Lumbricus terrestris) Characteristics: Common earthworms are in the phylum Annelid, and their scientific name is . All earthworms are eukaryotic, and they are heterotrophs meaning that they cannot make their own food. This mean that … Read more
Aim The aim is to investigate the effect of salinity or NaCl with concentrations in each trial on the mass of growing mung beans, and to determine which type of liquid is better for the mung bean to grow in. Background Information As I am studying the biomass of growing mung beans I have decided … Read more
Nutrition Structures and Mechanisms The digestive system of the earthworm is divided into many different sections, each of which have a certain function. These different digestive systems consist of the oesophagus, the intestine the pharynx, the crop and the gizzard. Food is swallowed by the pharynx as it enters the earthworms mouth, this includes such … Read more
Investigative Question Can steam produce enough power to generate electricity? Research What is steam Steam is the gas phase of water. Steam is formed when water boils. Steam is invisible but it refers to wet steam, these water droplets are formed as water vapour condenses. If steam is heated much further, it is then known … Read more
The scientific revolution was the arrival of modern science during the early modern period, with significant advances in physics, astronomy and mathematics helping lead to a transformation in societal viewpoints about nature and life itself. With this advancement, the scientific enlightenment emerged, and the Renaissance was born. A radical change in art, science and culture … Read more
Abstract: Chronic myeloid leukemia (CML) remains as a malignant clonal disorder featured by virtue of hyperproliferation of myeloid cells localized in peripheral blood, spleen as well as bone marrow [1]. many cases of chronic myeloid leukemia (CML) are recognized amid blood tests did for another reason. patients with Chronic myeloid leukemia (CML) and BCR-ABL T315I … Read more
Abstract: Rheological, chemical and sensory properties of processed cheese fortified with different levels of tomato (1%, 2% and 4% wt/wt) and asparagus (0.5%, 1% and 1.5% wt/wt) powders were analyzed. Both of the powders decreased the pH and lipolysis indexes and increased proteolysis extent of processed cheese. Phenolic and lycopene content and antioxidant activity decreased … Read more
A synthesized BiVO4/TiO2 nanocomposite by hydrothermal method was employed for the removal of MC-LR. Response surface methodology (RSM) was applied to assess the effects of operating variables (pH, contact time, and catalyst dose) on the MC-LR removal. The coefficient of determination (R2) was calculated 98.7% for the response. The obtained maximum MC-LR removal efficiency was … Read more
