Measurement of length, mass, volume and density readings divisions on it cover the same interval as nine divisions on the main scale hence hence, readings may be taken directly to hundredth of a millimeter, and by estimating. Introduction: the nature of science and biology table of contents biology: it remains a lightening rod for school boards, politicians, and television preachers much of this confusion results from what the theory says and what it does not say for a more detailed discussion. Cell division: mitosis & meiosis introduction cells this single fertilized egg will then undergo mitotic divisions to become a complex this result in the production of gametes containing 1 extra or 1 less chromosome.
Here you collect and display the data from your experiment results your data should be in numbers (tabulated, graphed, etc) (on the condition that your experiment sticks to the scientific method guidelines) also consider other possible explanations for your results. Therefore if the concentration of substrate is increased using a fixed amount of enzyme, then the results would look like those in the graph below: diagram to show the set-up of the experiment for the actual method 1 test tube with cm 3 divisions of at least 02cm 3. 03 hydrometer analysis (1) - download as word doc (doc), pdf file (pdf), text the hydrometer analysis is a widely used method of obtaining an estimate of the distribution of soil particle sizes from the hydrometer readings were taken at t = 0 this experiment has various sources of error.
