Relating Mass and Volume Question: What does mass have to do with the amount of space (volume) a liquid occupies? Hypothesis: I believe that the mass and volume is related because they both rely on each other for their purpose. If we fill the cylinder to a certain measurement (volume)‚ then the mass will grow with it. There is a balance. Materials: - Distilled water - Corn syrup - Saturated solution of salt water - Triple beam balance - 150 mL (or larger - Small plastic pipette - 150 mL beaker

The Feeding Behavior of the Protist known as Tetrahymena vorax Abstract The purpose of this experiment was to study the rate of phagocytosis of the specific protist known as Tetrahymena vorax. This certain kind of protist feeds at a normal rate when conditions are normal. We began the experiment of understanding how Tetrahymena feeds at normal temperatures. Doing so‚ we allowed the Tetrahymena to feed at specific time limits and then killed the protist with gluderaldheyde to detect how much

IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

Biology Notes 1.02 Sometimes a practice or belief claims to be science but does not follow the scientific method or cannot be proven reliable through experimentation. These practices are examples of pseudoscience‚ which literally means "fake science." Charms‚ astrology = stars‚ and phrenology= reading the bump on skull 1.03 * In the mid 1600s in the Netherlands‚ the scientist Antonie van Leeuwenhoek developed the first known microscope using a single magnifying lens.

Question 1 Surface level diversity Surface level diversity are those differences that are easily noticeable such as age‚ gender‚ ethnicity/race‚ culture‚ language‚ disability etc. Surface level diversity is easy to be measured and managers/recruiters can fall into the wrong practice of discrimination based on these factors. For example‚ thinking that performance degrades with age‚ they might prefer younger workforce. Surface level diversity is often difficult to change. For e.g. racial differences

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 that govern all study and research‚ consolidating it into single‚ coherent field. In general‚ biology recognizes the cell as the basic unit
