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

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

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’’

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

Food deserts are places where at least 500 people or a third of the population reside more than one mile from a supermarket or large grocery store — according to the CDC‚ “Food deserts are areas that lack access to affordable fruits‚ vegetables‚ whole grains‚ low-fat milk‚ and other foods that make up the full range of a healthy diet” (CDC). Furthermore‚ these food-deprived areas may exist in both rural or urban areas‚ but only in locations where there are geographic or socio-economic problems.

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

The objective of this lab was to recreate the color profile of a given solution. In this case‚ the solution was Powerade. The final solution should match the absorbance values at the peak wavelengths (420nm and 628nm) in Powerade. This lab was done using deionized water‚ FD&C Blue #1‚ FD&C Yellow #5‚ FD&C Red #40‚ and a spectrometer. To obtain the correct color profile‚ FD&C Blue #1 and FD&C Yellow #5 were utilized in the sample solutions. The experiment was conducted over two days; the first day

The purpose of the lab is to identify the compound based on a constant composition by performing a serious of tests. The hydrate is solid crystals compound and appears to be dry: since an ionic compound (salt) is crystallized from an aqueous solution (water)‚ by heating the hydrate the water is released from ionic structure; therefore it is possible to measure the weight of the ionic compound and calculate its ratio to the liquid in the hydrate. The goal of the lab is to establish the identity

Introduction: There are times when it is necessary to go through something both inside and outside‚ literally‚ to learn. This was exactly the case with virtual lab #11 where the experiment called for an examination of an earthworm’s exterior anatomy and interior anatomy. The earthworm as a whole is considered the dependent variable as we cannot change it. However‚ the labels to be placed can be moved so they are the independent variables. My hypothesis is quite elementary. I believe that after studying
