Introduction: The objective of this experiment is to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this

several main parts‚ including the egg shell (that acts as the cell membrane)‚ the egg yolk and the egg white. There’s also a tiny white mass that is very important‚ it’s called the ovum‚ and it is the living part of the cell. If a hen lays an egg without mating with a cock then the ovum will not develop. If the hen does mate‚ then the egg will be fertile and it develops into a little chick. The egg being worked with in this experiment is not fertile (Lawrence Hall of Science 2009). The egg white

Kevina Smith Lab 1: Microscopy and the Metric System Part A: Microscopy Purpose The purpose of this experiment was to learn how to use a microscope correctly and perform wet mount slides accurately‚ thus becoming more familiar with the microscope. Hypothesis It would be hard to use the microscope without any kind of previous training and the parts of the microscope and their functions must be learned in order to use it properly. Materials & Methods Materials: 1. Filter paper

Computer Simulation of Cell Transport Mechanisms and Permeability: Passive Processes and Active Processes Introduction In this lab we will establish a difference between the two types of cell transport mechanisms and their permeability. The first type of cell transport is passive processes which are driven by concentration or pressure differences in the interior and exterior of the cell. The second type is active processes which use energy known as ATP to power the transport. There are two

levels off with time include (1) equilibrium and (2) hydrostatic pressure. Equilibrium refers to the concentrations becoming equal. If there is no longer a higher concentration and lower concentration between the water and sucrose‚ osmosis can no longer take place. Osmosis can only occur when water is traveling from a higher concentrated area to a lower concentrated area. Hydrostatic pressure occurs when the bag reaches maximum capacity. Water will enter the bag through osmosis but get pushed out through
