Results: Since the mass of the ball bearing used in this experiment was very light‚ 20 balls were measured and the result was divided by 20 for better accuracy. This procedure was repeated for the sizes and the results are as follows: Diameter (mm) Mass (kg) 2 0.04 3 0.075 4 0.11 To find out the densities of the three balls‚ the following formula was used: Density= (mass of the ball)/(Volume of the ball)= mass/(4/3 π r^3 ) Density of 2mm ball = (0.04⁄1000)/(4/3 π 〖(0.001)〗^3

Planarian Lab Report Hanna Klein Bishop Fenwick High School Planarian Lab Report Introduction Planarian worms are free-living flatworms that are not parasitic. Planarians have a three-cavity digestive system. Planarians are usually either carnivorous or scavengers. Planarians may eat other living‚ as well as dead‚ invertebrates‚ detritus or decaying organic matter. Planarians do not realize that are eating a lot‚ and can over eat resulting in death. Most planarians are freshwater forms that can

Bacterial Transformation Lab Report Backround: The plasmid pGLO contains an antibiotic-resistance gene‚ ampR‚ and the GFP gene is regulated by the control region of the ara operon. Ampicillin is an antibiotic that kills E. coli‚ so if E. coli‚ so if E. coli cells contain the ampicillin-resistance gene‚ the cells can survive exposure to ampicillin since the ampicillin-resistance gene encodes an enzyme that inactivates the antibiotic. Thus‚ transformed E. coli cells containing ampicillin-resistance

Zach Sexton December 4‚ 2014 Bot 121 Lab Coleus Lab Report 1. A cutting can form an entire new plant if cutting being used has a meristem. If the cutting has no meristem‚ mitosis will not occur and you will end up with a dead piece of plant material. In order to successfully grow a new plant through a cutting‚ your plant must have adventitious root growth which in order to deliver water and nutrients to the plant. Adventitious roots are created through cell potency where cells differentiate. The

[Name] [Teacher] [Course] [Date] Catalase Lab Report An enzyme is something that helps to speed up a chemical reaction. The enzyme changes from reaction to reaction‚ but it always has the same impact. However‚ certain variables may cause the enzyme to have a more or less significant impact on the speed of each reaction. One of these variables that changes the effectiveness of an enzyme is temperature. There is an optimal functioning temperature for each enzyme in each reaction‚ depending on
