Lab Report #1 Ahmad Dweik Question/Problem Which phase of cell division / mitosis is seen most often in whitefish blastula? Introduction Cell division is the process of a parent cell dividing into two daughter cells. Mitosis is a type of cell division. In mitosis a parent cells chromosomes are copied and separated into two cells with different nucleuses but same DNA. There are steps or phases that take place that make the cell divide. The first phase is called Interphase. In interphase

Purpose: Examine the role of the cell membrane in the cell by disrupting its function using temperature (Biology 107 Laboratory Manual 2014). This will improve the general understanding of optimal growing temperatures and the breakdown of the cell membrane Procedure: Betacyanin solution of a known concentration was diluted to create a dilution series‚ then placed in a spectrophotometer set to 525 nm. The absorbance of the dilution was used to create a standard curve for betacyanin. Discs of living

1. Should the Silicone-X project be undertaken? Why/why not? After completing the analysis and reviewing the NPVs and IRRs for each option‚ labor intensive and capital intensive‚ Soderberg should recommend that the Jacobs division move forward with production of Silicon-X using the labor-intensive option. The NPV and IRR methods make the same decisions if used for independent projects however‚ since these projects are mutually exclusive‚ the best NPV option should be used. In this

Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The
