Title: Laboratory 2: Measurement of Biochemical Oxygen Demand (BOD) Objective To determine the amount of oxygen necessary for biological oxidation of wastewater effluent and determine the amount of oxygen required by bacteria while stabilizing decomposable organic matter. Methodology Apparatus ; Biochemical Oxygen Demand (BOD) meter‚ Dissolved Oxygen bottle (DO bottle)‚ pipette‚ Teflon tape‚ dilution water‚ incubator machine. Procedure; Add 300 ml dilute water then take DO reading immediately

increasingly complex models at all levels of biology. This paper shows the innovations in studying biology. It discusses the biological level of organization and it also describes the model that has seem to be found on the said level. It was also discussed on this paper that the complex models that was developed for the past few years must have the new methods and techniques to model it. The journal tackles the level of organization‚ multi-scale in modelling in biology‚ MD of ion channels and heart modelling

Lauren Spillers Biology 1408 February 5‚ 2013 Lung Cancer Lung cancer is the number one form of deadly cancer in the United States. It is not only something that can kill you but also can put a strain on you and your family financially‚ emotionally‚ and medically. Lung cancer is formed when the cells of the lungs grow in an uncontrolled way‚ this creates a lump or a tumor which can either be malignant (cancerous) or benign (not cancerous). Radon gases‚ smoking‚ and second hand smoke cause lung

Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it which govern all study and research‚ consolidating it into single‚ coherent field. Biology generally recognizes the cell as the basic unit

BIOLOGY Biology is the study of life -- life in all of its grandeur. From the very small algae to the very large elephant‚ life has a certain wonder about it. With that in mind‚ how do we know if something is living? Is a virus alive or dead? What are the characteristics of life? These are all very important questions with equally important answers. Characteristics of Life Living tings include both the visible worlds of animals and plants as well as the invisible world of bacteria and viruses.On

Avery’s Experiments In 1944‚ a series of experiments showed that the activity of the material responsible for transformation is not affected by protein-destroying enzymes. The activity is stopped‚ however‚ by a DNA-destroying enzyme. Thus‚ almost 100 years after Mendel’s experiments‚ Oswald Avery and his co-workers demonstrated that DNA is the material responsible for transformation. Viral Genes and DNA In 1952‚ Alfred Hershey and Martha Chase used the bacteriophage T2 to prove that DNA carried
