to observe the hypothesized correlation between ionic strength and degree of ionization of a weak acid‚ while determining the factors that would impact the degree of ionization using measurements of pH. It was initially required to prepare standard 20-mL solutions of varying concentration of acetic acid for use in the rest of the experiment. One solution of CH3COOH was supposedly developed to be 2.00M‚ however it is highly possible that the solutions of CH3COOH were not exactly the expected concentration

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Applied research: Research that is done for a clear‚ practical purpose. For example‚ a study to determine whether breast-feeding is beneficial to children’s later intelligence is an example of applied research because it has an immediate practical use. Basic research: This builds psychology’s general knowledge base but has no immediate applications. For example‚ a study determining whether identical twins’ personalities are nature- or nurture-oriented is an example of basic research. Terminology

Jennifer Obrien Date: 11/ April 11‚ 2013 Abstract Inexpensive‚ affordable food is a person’s wants. If find some ways to solve this problem‚ keep food quality and price. So‚ in this paper discuss the solution of how to strike a balance between inexpensive‚ affordable food and healthy‚ quality food. Firstly‚ according to international trade‚ people can import some healthy food from other country‚ which place has lower labor. So‚ people can control the

Professor Tolentino Maria Oyervide EXPERIMENT #4 IONIC AND COVALENT COMPOUNDS Abstract: This experiment was divided in four steps to find the electrical conductivity of covalent and ionic solutions. There were four unknown solutes A‚ B and C. Each had a specific weight and was dissolved in a certain amount of solute to form either the covalent or ionic solution. Covalent compounds are made up of molecules which are electrically neutral. Ionic compounds are composed of ions‚ which are positively

there is not a single way of addressing that problem. Here after is a brief investigation of “two of the approaches” we have been taught in Psychology “Biological and Social approaches”. What are “biological” and “social” approaches in psychology? “Biological approach” in psychology “examines thoughts‚ feelings‚ and behaviours from a biological point of view”. It is thought that we are consequence of our genetics and physiology. “Social approach” in psychology studies how people act‚ think‚ and

The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water? Water
