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’’

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

with the lab equipment such as the microscope‚ square glass‚ cover slips‚ etc.; to facilitate students to observe the pond water; and enable them to discern and identify the microbes as bacteria‚ algae‚ fungi‚ or protozoa within the pond water. Additionally‚ this lab experiment will permit students to observe and distinguish the yeast suspension from the other microbes. Data/Results: (Attached) Conclusion: The student acquired the fundamental skills in which to properly handle lab equipment

What is the effect of a non-volatile impurity on the boiling point of a substance? of a volatile impurity? A non volatile impurity which is added to the volatile liquid‚ it’s boiling point will increase. It is due to some of effective surface area which is available for evoperation is occupied by non volatile substance. If another volatile impurity is added then 1) if it does not chemically react with given liquid then boiling point will decreade due to increase in vapour pressure. 2) if it chemically

Introduction My unknown organism #6 is Morganella morganii‚ which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans‚ mammals‚ and reptiles as a normal flora. (3‚ 5) This bacterium Morganella morganii‚ was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide

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
