CORROSION AND ITS CONTROL CORROSION * corrosion can be defined as the degradation of a material due to a reaction with its environment. * Degradation implies deterioration of physical properties of the material. This can be a weakening of the material due to a loss of cross-sectional area‚ it can be the shattering of a metal due to hydrogen embrittlement‚ or it can be the cracking of a polymer due to sunlight exposure. * Materials can be metals‚ polymers (plastics‚ rubbers‚ etc.)‚

The first half of module seven discussed protein digestion‚ absorption‚ and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚

discuss the evolutionary relationships between the two members of each pair you have chosen. In your discussion include structural adaptations and their functional significance. a. Green Algae...Vascular Plants b. Prokaryotes....Eukaryotes a. Green Algae and Vascular Plants have clear evolutionary relationships. Both Green algae and vascular plants have many similarities displaying this fact. Just a few of these similarities include that both groups have chloroplasts with chlorophyll

Rules of attraction: Biological and evolutionary reasons of mate choice ABSTRACT Within the past decade we have witnessed a series of new developments and an enormously growing interest in the understanding of human behaviour‚ especially when it comes to the basic principles of human mate choice. Mate preference is something which is often considered a very individual choice and appears to be influenced by cultural and economic norms. However‚ on the basis of numerous research works‚ it is

question ask is‚ how big is my protein footprint? It also asks‚ does a meat rich diet have a negative impact on our environment? And does it contribute to global warming? With a very small percentage of Americans following a vegetarian diet. I will say that my protein footprint is about the same as the majority of the US population. I understand that a good source of protein can be found in nuts‚ black beans and lentils. However the number one source of protein in a US household‚ comes from

Discuss the evolutionary explanations of functions of sleep. (24 marks) The evolutionary theories suggest sleep has evolved because it gives an animal a greater chance of survival when in a dangerous environment. They also suggest that sleep has evolved because it conserves energy and coincides with their eating habits. The evolutionary explanation (also referred to as the ecological approach) is based on the observation of animals in their natural environment. The evolutionary approach to

glucose. This release of products provides the necessary nutrients for all forms of life. In water‚ leaves‚ usually float in water due to the gases such as carbon dioxide and oxygen that are within the mesophyll layer of the leaves. But in order to measure the rate of photosynthesis‚ the gases in the leaves need to be drawn out of the mesophyll. This can be done by creating a vacuum‚ which will further be explained in the procedure. This will allow us to see the effect of one reactant‚ carbon dioxide

of a functional recombinant fusion protein via the directional sub-cloning of an E.coli derived tyrosine phosphatase gene (wzb) into a pT5(6H)CFP mutant expression vector. Abstract: Application of fluorescent fusion proteins to the field of expression and interaction proteomics as a means of dynamic imaging proteins in vivo has allowed for rapid advancements in biotechnology research. Production of such proteins first involves the insertion of a given protein-coding gene transcriptionally in-frame

PSYCHOLOGICAL MEASURE INTRODUCTION The process of developing a reliable and valid psychological measure is a complex task. In this paper‚ the author hopes to further explain how to construct a test which can be considered both valid and reliable. Steps to developing a psychological measure The steps to follow when developing a psychological measure can seem daunting and complex. There are nine basic steps which need to be followed: 1.THE PLANNING PHASE This is where the aim of the measure needs to
