The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

immune system. The neutrophils are the most common and are a bacterial response. Therefore if the patient has a high amount of neutrophils you know that the patient is fighting bacteria. They have 3 to 5 lobes in their nucleus with granules within the cytoplasm. The way they kill bacteria is by engulfing the bacteria cell and dissolving the contents. Lymphocytes attack a viral infection and are similar size to red blood cells. They have a large nucleus taking up 95% of the cell with very little

Introduction: The purpose of this lab is to apply Mendel’s laws to predict the probability of the occurrence of a single event‚ of two independent events and of certain traits in offspring of parents exhibiting traits. Gregor Mendel was an Austrian monk in 1866‚ who studied how traits were passed using pea plants. From his studies of inheritance‚ he created three laws of inheritance: the law of dominance‚ the law of segregation‚ and the law of independent assortment. He called genes ‘’factors’’

Osmosis Lab Research Question: In this lab‚ our goal was to look at the effects of different sucrose concentrations on osmosis in potatoes. Our research question was “How do the sugar levels affect the rate of osmosis in potatoes?”. Background Information: Solutions consist of solutes dissolved in a solvent. In all living organisms there are many different types of solutes including salts and sugars. The major solvent is water. There are different concentrations of solutes in various regions

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

In this enzyme lab‚ (insert creative name)‚ the enzyme catalase was observed under varying conditions in order to interpret what prohibits and inhibits the functioning of certain enzymes in chemical reactions. Enzymes aid in chemical reactions by speeding up the time it takes for the reaction to occur‚ without getting “used up” throughout the process. Catalase‚ the specific enzyme used in this lab‚ is a protein abundant in the liver and red blood cells. It enhances the breakdown of hydrogen peroxide

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda

Termite Lab Report The effect of ink on termite behavior Abstract Termites produce special chemicals within their bodies called pheromones. Because termites are usually found inside dark areas‚ pheromones help them communicate in these places. Past studies have suggested that ink inside ballpoint pens contains pheromones‚ causing termites to follow any trail created by the ink. If a pathway is drawn with an ink pen‚ then a termite will be attracted to the path and trace it due to the pheromones

Erin Gaudet SCI-220-01 Title: Hair Lab Object: Analyze hair samples Procedure: Same as in lab handout Results: See attached data sheet Conclusion: This type of lab analysis is important to the field of forensic science because you could link a person to a crime. The removal of hair from the body often denotes physical contact between a victim and perpetrator and hence a crime of a serious or violent nature. Forensic scientists would find this lab useful because they would be able to determine

Introduction: The purpose of this lab is to see how the colour of an apple would change (browning) over time‚ when placed in different conditions. When referring to the term “browning”‚ it is meant to imply the change of colour that occurs inside the apple‚ giving an appearance that is distasteful (Di Guardo et al.‚ 2013). Specifically‚ within this lab the apple was cut into 4 pieces with 3 pieces being placed on a weigh boat‚ and a 4th piece placed in a beaker of water. These weigh boats were
