After that, I placed the slide under the microscope and began searching for the cells that were on the slide. Method: Fish Cells First I chose a slide with fish cells on it, then I placed it under the microscope. I then began searching for the different stages of mitosis in the cells. I then took pictures of the slide, and drew pictures of the the different stages of mitosis. Conclusion In conclusion, after learning to make a cheek cell slide and viewing both the cheek cells and the fish cells in the microscope, I could identify the stages of mitosis.
It goes in depth of how many times mammal clones were attempted to be created, and how many times they actually succeed. It also speaks in regards to how clones are made. I would use this in my paper in regards to adding ethos, or credibility to my paper. It will give facts involving how many attempts were made to create clones. 5. http://learn.genetics.utah.edu/content/cloning/whatiscloning/ This site gives information on how technology plays a role in how clones are created.
6.05 HONORS Lab Report: Dichotomous Key Directions: Use the Dichotomous Key on my site as you carry out this lab. Read all of the instructions below carefully, and fill out the BLUE portions of this sheet. Objectives: After doing this lab activity, you should be able to: Identify bryophytes, pteridophytes, gymnosperms, and angiosperms. Describe the characteristics and classification of the four main plant divisions. Materials: Four plant samples Dichotomous key (a copy is found in the Module Help column at www.rechanek.com) This lab report Hypothesis: 25% Bryophyta 25% Pteridophyta 25% Gymnosperms 25% Angiosperms Procedure: Read all the instructions for this lab before you begin working!
Purpose: The lab exercises will allow you to experience the techniques used to investigate basic cell structure, observe differences between generalized and specialized plant, animal and protozoan cells, and to increase your observation skills. Procedure: Part 1 1.Use the onionskin given to you by the teacher and place a drop of iodine onto the onionskin. 2. Then place the skin under the microscope and observe. 3.
Biology lab: Methods and Results February 14, 2012 Genus species Methods: In order to conduct our experiment we started off with two petri dishes, six antibiotics and two types of bacteria to run our experiment. The bacteria that were being used in this experiment were E. coli and S. Marscescens. The antibiotics that are being used to combat the bacteria are called Penicillin (1929), Streptomycin (1947), Erythromycin (1952), Ampicillin (1961), Gentamicin (1971), and Ciprofloxin (1987). In the two petrib dish, each is individually chosen to be for E. coli and for S. Marscensen. At the bottom of the petri dishes we level it with four quadrants to make sure that each of the antibiotics were placed in the right quadrant and be able to see how the bacteria acted in respect to the placement of the antibiotic.
As part of an undergraduate project, a student was attempting to construct a restriction map for the plasmid pUC23 using the restriction enzymes EcoRI and BamHI. After carrying out both single and double enzyme digest reactions and electrophoresing each reaction mix through an aragose gel, the picture below is obtained, showing the number of DNA fragments produced in each reaction, along with the sizes of each fragment. From this information, construct a restriction map of the pUC23 for enzymes EcoRI and BamHI. Digest Performed: Sizes of Fragments Obtained:
Lab Report: “The Unknown” NAME: Donnise Warren PURPOSE: The purpose of this lab report is for students to be able to identify an unknown bacterium given to us by doing a variety of lab procedures and biochemical lab test to help identify what specific bacteria we have. INTRODUCTION: There are many reasons for knowing the identify of microorganisms. Such as knowing the causative agent of a disease that a patient may acquire, so that you would know how it could be treated, to knowing which microorganisms could be used for making antibiotics or even food. This lab report was done by implementing methods that have been learned throughout this semester in our microbiology lab course which helped identify my unknown bacterium #115. 6/28/2012 The 1st lab procedure performed was the gram stain.
Pre-AP Biology Summer Work General Instructions Or “What do I do with all the stuff in this packet?” Welcome to Pre-AP biology. I hope you are ready for a fun-filled, exciting year. I have put together a packet of information and assignments that will get you started on your road to biological success. One of the first things you will need to do is become familiar with my website. The Laboratory Equipment page should be colored and studied.
Blanca Mbuto 02/19/2012 Biochemistry Lab 4422 Cell Fractionation by Centrifugation Abstract This experiment was performed to investigate organelles, membranes, cellular components, and enzymes. Our concentration was to observe and determine if the chlorophyll contained broken chloroplasts or intact chloroplasts extracted from spinach leaves. A percoll density gradient was prepared followed by the separation of organelles. Chlorophyll was analyzed by using a spectrophotometer. We compared the absorbance readings of each tube and selected three (3) tubes to be analyzed.
This laboratory allowed individuals to view erythrocytes and leukocytes under different magnification levels. Using This lab people can learn to examine, illustrate and estimate the size of these neurons, erythrocytes and leukocytes under 100x. He/she look at these neurons, erythrocytes and leukocytes and can draw and label them, giving us a better knowledge of how these specimen look in millimeters and microns. Materials: • Microscope • Clear Ruler • Slide of Neuron • Blood Sample Slide Methods: Step 1: Grab slide of the specimen being observed and place it on the stage of the microscope. Turn Microscope on.
