DNA DNA‚ or Deoxyribonucleic Acid‚ is described‚ in Encarta Encyclopedia as a genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus‚ passing on the information needed for protein synthesis. In most cellular

By using this information effectively‚ staff‚ parents and children‚ where appropriate‚ can create and maintain plans which help to provide a focused and individualised approach. When making observations‚ staff can avoid being judgemental or biased in their

the Scientific Method Can Apply to Human Services This paper will offer explanation of how scientific research can be used in the Human Service field. The paper will also explain the steps involved in scientific inquiry and why the steps are of importance‚ and then provide an example a scientific method related to the Human Services field. Next discussed will be a brief description of quantitative research and qualitative research‚ explaining the differences in both models and how the methods relate

SOLVENT EXTRACTION Solvent extraction‚ also known as liquid extraction and partitioning‚ is a method to separate compounds based on their relative solubility in two different immiscible liquid‚ usually water and organic solvent. It is an extraction from one liquid phase to another liquid phrase. Liquid extraction is a basic technique in chemical laboratories‚ where it is performed using a separator funnel. This type of process is commonly performed after a chemical reaction as part of the work-up

Discussion: Extraction and crystallization- The purpose of this lab was to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to

Extraction of Caffeine from Tea Leaves Jaybee Balilea‚ Sharmaine Baysic‚ and Maria Anjelette Patricia Belen 3BIO7‚ Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Extraction is a technique for isolating and purifying organic substances. In this technique‚ a solution is combined thoroughly with a second solvent that is immiscible with the first solvent. The solute is extracted from one solvent into the other because it is more soluble in the second solvent

objects as shoreline features. A contouring routine is developed as an alternative method for extracting shoreline features from LiDAR data. While most of numerical algorithms are implemented using C++ programming language‚ some algorithms use available functions of ArcObjects in ArcGIS. Based on VB .NET and ArcObjects programming‚ a graphical user’s interface has been developed to integrate and organize shoreline extraction routines into a software package. This product represents the first comprehensive

History books all over the wolrd. Bacon aided to some of the greatest‚ most useful scientific advances of all time that affect people today. Although Bacon’s contributions were majorly philosophical‚ he helped change the direction of scientific advances. He shifted the idea of using deductive syllogism‚ as proposed by Aristotle‚ to inductive reasoning from fact‚ axiom‚ to theorem. The scientific and philosophical contributions that Francis Bacon gave impact the world today. Bacon and Rene

I chose is how the scientific method has changed over time and if it is more less effective at achieving its goals? I will discuss this question in both sides during this essay. I preferred this question than the other questions because it is a strong question and I would like to discover more and research deeply in this investigation. The scientific method has been existing over a thousand years ago to be specific the science method started in the 17th century and methods of scientists has changed
