2.1 Cell Theory 2.1.1 Outline the cell theory The three main principles of the cell theory are: * All organisms are composed of one or more cells * Cells are the smallest units of life * All cells come from pre-existing cells New Concepts * Cells contain the blueprint for their own growth‚ development and behavior * Cells are the site of all the chemical reactions needed to sustain life * Cells (and multicellular organisms) show emergent properties – appears as complexity

Lacsap’s Fractions IB Math SL Internal Assessment Paper 1 Lacsap’s Fractions Lacsap is Pascal spelled backward. Therefore‚ Pascal’s Triangle can be used practically especially with this diagram. (Diagram 1) This diagram is of Pascal’s Triangle and shows the relationship of the row number‚ n‚ and the diagonal columns‚ r. This is evident in Lacsap’s Fractions as well‚ and can be used to help understand some of the following questions. Solutions Describe how to find

molecules need to be broken down into smaller ones for absorption to occur. Summary: 1. Food needs to be broken down and reassembled. 2. Large food molecules need to be broken down into smaller ones. 6.1.2 Explain the need for enzymes in digestion. Enzymes are needed in the process of digestion as they are the biological catalysts which break down the large food molecules into smaller ones so that these can eventually be absorbed. Digestion can occur naturally at body temperature‚ however

like: "Salivary Amylase is a an enzyme that digests starch into di- and monosaccharides. Since it’s a salivary amylase‚ the enzyme works best at an alkaline pH of 7‚ in other words‚ the optimum pH is 7. At this pH‚ the rate of amylase activity will be at it’s highest. A pH that is much lower (very acidic) or much higher (very alkaline) will denature the enzyme permanently (specifically the active site)‚ and the enzyme can’t function anymore. The activity of the enzyme will decrease as we increase or

For its external structure‚ Lacsap’s Fraction is analogous to Pascal’s Triangle. Lacsap’s Fraction presents the way of generating and organizing the binomial coefficients. Within this investigation‚ the work is planning to be divided into two parts. In the first part‚ the content will relate to the pattern of numerators. In the second part‚ I am going to do the

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of
