John Leone Lab Partner(s) Ethan Davis & Ryan Hanna Date: 12/10/14 Instructor: Dr. Chuckran Period: H Plants and Animal Cells Abstract: In this lab‚ you will find out how plant and animal cells are alike and how they are different. The onion elodea cells were both plants‚ so they had a cell wall. The cheek cells were animal cells‚ so they did not have a cell wall. Eukaryotic cells contain structures called organelles that carry out life processes. Eukaryotic cells can be classified by the types of organelles they contain

and centrifuged for 20 seconds. A polyacrylamide gel was assembled and the samples were loaded into it. The gel ran for approximately 45 minutes at 160 V. A western blot analysis was done in order to examine the Erk1/2 phosphorylation of the NIH3T3 cells. Three pieces of Whatman paper were wet in transfer buffer and placed on the anode plate. A wet PVDF membrane was placed on top of the Whatman paper. The gel was removed from holder and the stacking gel was removed. Forceps were used to place the gel

Methods for studying cells in the lab Centrifugation A centrifuge is a device for separating particles from a solution according to their size‚ shape‚ density‚ viscosity of the medium and rotor speed. Centrifugation can be used to separate cells from one culture or to isolate an organelle from the rest of the cell. The process relies on speed; the faster and longer the particle is centrifuged‚ the smaller the particles are that will be separated. Separation occurs by causing the larger particles

Unit 10: Blood/Immunology Case Study Lab What were your three diagnoses? Case 1: Bacterial or viral infection Case 2: Normal blood smear Case 3: Normal blood smear Journal Questions for lab In what ways do normal red and white blood cells differ? White blood cells have a nucleus‚ red blood cells do not‚ white blood cells protect while red blood cells transport‚ red blood cells have a longer life span than white blood cells. Which type of white blood cell would you

Lab design –Voltaic Cells Aim Of Experiment In this experiment‚ we are going to make a battery by making an electron current between the metals Zinc and Copper. We aim two study the voltaic cells and the transfer of electrons from the metal to the ion. The tendency for the electrons to flow from one chemical to another‚ such as from the zinc metal to the copper ion as shown here‚ is something that can be channeled and controlled. Channeling the flow of electrons is what we will take up in this

Electrochemical Cells Lab Report AP Chemistry Block 1 Analysis: The purpose of Part 1 of this laboratory is to construct a table listing the reduction potentials of a series of metal ions in order of ease of reduction. The series of half-cells is constructed by placing a piece of metal into a 1.0 M solution of its ions for each metal in the series. The metals are Cu‚ Fe‚ Pb‚ Mg‚ Ag‚ and Zn. The half-cells are connected by a salt bridge constructed of a strip of filter paper soaked in a solution

Introduction: What is Blood Pressure? Blood Pressure can be defined as the force per unit area exerted on a vessel wall by the contained blood in the heart‚ and is measured by millimeters of mercury (mm Hg) (Marieb‚ 703). Each time the heart beats (which is about 60-70 times a minute at rest); it pumps out blood into the arteries. There are two types of pressure recorded that can determine your blood pressure. Your blood pressure is at its highest when the heart beats‚ pumping the blood. This is called

Veins need valves to create pressure to pump the blood to the heart. Blood flows away from the heart and‚ therefore‚ the pressure is not required. Helps against gravity. 6 NAME TWO EVENTS OCCURING WITHIN THE BODY THAT AID IN VENOUS RETURN. 1. Respiratory

The Effect of Temperature on Beet Cell Membranes and Concentration of Betacyanin Released Introduction Membranes are an important feature of plant cells and they act as a barrier that separates the interior of the cell from the external environment (Campbell et al.‚ 2008). Each membrane layer is composed of a phospholipid layer‚ which is semi-permeable and possesses the ability to control the movement of diffusion. Within the centre of a cell‚ the vacuole that is responsible for storage and

Differentiating Between Prokaryotic and Eukaryotic Cells‚ Distinguish Among Plant‚ Animal‚ and Protist Cells‚ and Identifying the Organelles that are Evident in Them Introduction There are two different types of cells‚ prokaryotes and eukaryotes. Prokaryotes‚ such as bacteria‚ lack a nuclear membrane and other membrane bound organelles. Their genetic material consists of a single molecule of singular DNA. Eukaryotes‚ such as plant and animal cells‚ have a nuclear membrane and other membrane bound
