cells that we observed were yeast cells. Under the microscope, the only observable differences between the yeast cells and the prokaryotic cells that we have looked at, is that the yeast cells are larger and some cells appear to be budding. When viewed under Phase Contrast, the yeast cells shows different level of contrast on its membrane, possibly due to the organelles within the cells. Other differences that were not observable under the microscope, is that yeast, being a eukaryotic, contains…

the two different trials for the two different Planaria tested. After, the values were translated into graphs in order to get visual perspective on the results. As observed the trials the Planarian was the slowest under the natural light of the microscope (control), was a bit faster under the violent light which had the highest frequency, a bit faster under the green light with the intermediate frequency, and the fastest under the red light which had the lowest frequency. These results can be…

apart from one another and allow them to survive in these environments. Through macro and microscopic observation, different microbes can be observed through the natural liquid and solid phases and be made into slides to be viewed closely under a microscope. Essentially, a random microorganism can be sampled in a dry environment and be identified through observing unique characteristics that would make the microbe be considered either a mold, yeast or bacterium. Using a nutrient agar plate and…

MBK – Lab Report Name: ___Melissa Callon _________________ Section: ___________________ Observing Bacteria and Blood Questions: @. A. List the following parts of the microscope and describe the function of each 1. Eyepiece: x10 or x15 lenses used to look through to view objects within the viewing field 2.

transplant is the most popular method of hair transplantation in India. Here are some of the questions to ask if you are undertaking this method: Are the grafts divided by microscope? Do all the physicians utilize stereo microscopes? What is the time period of technicians using microscopes to divide follicular units? How many stereo microscopes are being made use of during a process? Does your hair transplantation physician use a single blade to eliminate the donor strip? What is the quantity…

A dissecting microscope was used to examine the current stage that the zebrafish embryo were in. Next, a compound microscope assisted with finding the details that were not visible to the naked eye and the dissecting microscope. In order to prevent the zebrafish from moving, anaesthesia was used. Photographs of the zebrafish were taken periodically using a Kodak Ektachrome…

Have you ever wondered when there comes a point in time where one might be able to see tiny germs without the use of a microscope? Well the time has come, scientists have created a type of bionic lens that allow humans to zero in on the tiniest of objects without the assistance of a third item such as the microscope. For hundreds of years, scientists have been using the microscopes to make major discoveries such as proving the existence of minuscule living organisms that cannot be seen to the…

Introduction Development, replication, and inheritance depend on the cell division cycle. A series of events is carried out in a cell leads to division and duplication. Two daughter cells get produced. Prokaryotes that lack a cell nucleus forms binary fission. Cells with a nucleus like eukaryotes the cell cycle are divided into three periods. Interphase, the (M) mitotic phase, and cytokinesis. In Interphase, the cell increases to accumulate nutrients needed for mitosis, preparing it for cell…

Repeat step 4, 3 times after refocusing the microscope to see a different pane of bacteria. 6. Repeat steps 1 through 5 for each of the conical tubes. Study 2 - Lake Water Experiment 1. Repeat steps 4 through 9 from Study 1 if more of the stocks is needed. 2. Label 12 separate conical tubes with…

The effect of caffeine on the heart rate of Daphnia pulex Introduction In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well. Carrie miller from university of…
