Pouri‚ Nikole Period 1 1/14/12 Mitosis Lab Write-Up Purpose: The purpose of this lab is to understand the phases of mitosis through a hands on experience and not just textbook information. The objective is to visually determine each phase through a microscope with a clear understanding of what is happening. With this knowledge and this visual a picture is to be drawn as descriptive as possible for each phase. Materials: The materials needed are; 1) Microscope 2) A slide containing plant

Mitosis Under Microscope Lab Report A. The purpose of the investigation is to determine the time an onion cell spends in each part of the cell cycle. B. The significance of this investigation is to help us understand and know how long cells are undergoing mitosis. My personal interest is to know the phases of mitosis in cells in order to someday help find cures for cancer. C. The cell cycle is a chronological set of events‚ culminating in cell growth and division into two daughter cells. Some

BIO Microscopy‚ Mitosis‚ and Motility Lab Discussion Questions In the Microscopy‚ Mitosis‚ and Motility lab‚ the class used the Compound Microscope. The Compound Microscope helped examine the prokaryotic and eukaryotic cells‚ observe the different stages of mitosis‚ and compare modes of motility used by protists. The light compound microscope works with the aid of lenses such as the eyepiece. These lenses help keep the focus of the light on the eye. The fine and course adjustments also assist with

MITOSIS The Stages of Mitosis Mitosis is simply described as having four stages—prophase‚ metaphase‚ anaphase‚ and telophase; the steps follow one another without interruption. The entire four-stage division process averages about one hour in duration‚ and the period between cell divisions‚ called interphase or interkinesis‚ varies greatly but is considerably longer. During INTERPHASE the chromosomes are dispersed in the nucleus and appear as a network of long‚ thin threads or filaments‚ called the

Conclusion 1: In this first lab we attempted to discover which of the materials given to us were hydrates by heating them and then dissolving them in water. Our results showed that all of our substances were hydrates besides the sucrose‚ sucrose if the only one which did not both bring condensation when heated and dissolve in water‚ which agreed with our hypothesis because we also thought that sucrose was going to be the only one that wasn’t a hydrate. The only error that we may have encountered

Lab Conclusion When comparing the average speed results from part two of the lab and the definition of acceleration‚ you find similarities between the two. First‚ average speed is distance divided by time‚ and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp‚ because it picks up speed. When the marble is released at the top of the ramp‚ the ball doesn’t have the same momentum

Conclusion In this experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest

Guided Inquiry • Skills Lab Chapter 11 Lab Modeling Meiosis Problem How does meiosis increase genetic variation? Introduction Most cells in organisms that reproduce sexually are diploid. They have two sets of chromosomes and two complete sets of genes. Gametes are an exception. Gametes are the cells that combine during sexual reproduction. In animals‚ these cells are called sperm and eggs. Gametes are haploid cells with only one set of chromosomes. Meiosis is the process in which haploid

Conclusion to Motion Lab Kerreon Wright 3rd Period Ms. Gislason The purpose of this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they
