Lacsap’s Fractions IB Math SL SL Type 1 December 11‚ 2012 Lacsap’s Fractions: Lacsap is Pascal backwards and the way that Lacsap’s fractions are presented is fairly similar to Pascal’s triangle. Thus‚ various aspects of Pascal’s triangle can be applied in Lacsap’s fraction. To determine the numerators: To determine the numerator (n)‚ consider it in relation to the number of the row (r) that it is a part of. Consider the five rows below: Row 1

Data: quantitative The data below is the raw data collected during the lab to test the photosynthetic rate of five different .75% colored bicarbonate solutions. Time taken for three spinach leaf disks to rise to the top of .75% bicarbonate solution (measured in minutes) Uncertainty +/- 10 seconds Uncertainty +/- 10 seconds Qualitative: This data is a record of the physical reactions or visual observations during the lab * Some of the leaf disks are not cut properly * Blue solution

Enzymes are biological catalysts that speed up chemical reactions by lowering the amount of activation energy needed to start the reaction and let the reaction occur at temperatures found in living cells. The way that enzymes do this is explained with the lock and key hypothesis. This hypothesis says enzymes have a specific shape called the active site which is different between different enzymes. Molecules called the substrate that participates in the reaction also have a specific shape that can

Enzymes are a major role in the process of accelerating chemical reactions. Environmental factors affect the enzymes‚ These environmental factors include ph levels and body temperature. While both of these environmental factors affect the enzyme‚ body temperature affects the enzymes the most and can result in death. Enzymes are affected by high body temperature. Enzymes are highly specific and they work at certain temperature levels depending if it’s hot or cold. However‚ when the

How can we recognize when we have made progress in the search for knowledge? Consider two contrasting areas of knowledge. The search for knowledge is a constantly ongoing process. So how are we to know if we have made any progress? Progress is development‚ advancement‚ and moving forward. In this case it is the progress in the search for knowledge in an area of knowing. Within the areas of knowing the strongest contradiction is between human science and natural science. Human sciences

There are COX enzyme isoforms include COX-1 and COX-2. (Figure 3.8) These enzymes originate from different genes and have distinct tissue-specific expressions and biologic functions. COX-1 is constitutively expressed in most tissues and believed to responsible for the production of prostanoids in homeostasis‚ such as gastric epithelial cytoprotection and renal blood flow maintenance. COX-2 expression is inducibly expressed only at marginal levels under condition in many tissues and is upregulated

pH Affecting on Amylase Enzyme Is there a difference in the concentration of pH in the amylase enzyme activity? The null hypothesis would be that there will be no difference in the concentration of pH and alternative hypothesis would be that there will be a difference in the concentration of pH. The predication if that there will be a difference in the concentration of pH. The pH affects on enzyme activities‚ one of the enzyme that was used in the process was amylase. When a serial dilution was

Lab Report Factors That Affect Enzymes Reaction Rate Name of lab: Effects of temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity Introduction: Enzymes are the most important types of proteins‚ they act as catalysis (speed up chemical reactions). If enzymes didn’t exist‚ biochemical reactions would act to slowly and they couldn’t keep up with the metabolic functions. Enzymes have a three-dimensional structure that is really complex. This structure consists
