Egg Break Lab Report

The solutions are 0% sucrose, 10% sucrose, 20% sucrose, 30% sucrose, 40% sucrose and an unknown sucrose concentration. We then weighed each egg separately to the nearest gram in order to have an initial starting weight to compare to the results throughout our experiment being conducted. The eggs were then placed in each beaker for 12 intervals at a time. After every 12 minutes the eggs were taken out and weighed to see if the weight of the egg changed. With a total of five intervals (12, 24, 36, 48, 60) the steps were repeated till the egg had reached the total time of 60 minutes. The changes in weight of the eggs were then added into a data table showing the weight of the chicken eggs in grams vs. the time in minutes. In a second data table the weight changes (g) vs. time (min.) between the eggs were taken and used the difference from each time and subtracted it from the initial

ADI Egg Lab                 Ritika Sharma Section 1: During the egg lab there was one guiding question we were trying to figure out. Which was what effect do different solutions (maple syrup, mouth wash, and saltwater) have on cell size? Before we started this lab we had to have our background information which was osmosis is when water moves from a high concentration to a low concentration through a membrane. We also had to know that hypotonic is when water is moving into the cell and the cell swells/expands.

The egg shell completely disappears due to the vinegar reacting with the egg; bubbles form on the surface of the vinegar and on the egg because carbon dioxide was produced from

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

Egg Drop Lab Essay Forces are around us all. They are everywhere you go. In this essay I will be talking about forces, motion, and energy and how they applied to our egg drop lab. For my hypothesis”If the egg as soft stuff on the outside of our container,then the soft stuff will absorbs the pressure and force that it goes through when it hits the floor. ”This essay will have multiple details on how the forces, motions, and energies were applied to our egg lab.

Conclusion: My hypothesis was incorrect because I had initially thought that the egg would shrink because of the pH of the vinegar, however the eggshell got larger rather than shrinking. This is because the homeostasis of the cell was disrupted, which in result interrupted the function of  the phospholipids. Enzymes, which whom are catalysts for chemical reactions in living things, can only occur under tightly controlled conditions such as a small range of temperature and/or pH. A disruption would cause the hydrogen bonds to break and that would not allow the cell to properly function. Since the enzymes were not able to function correctly under the desired conditions, it would cause the egg shell to dissolve. In addition, because the shell

An association between enzyme production, gene copy number, and gene evolution was explored by conducting analysis of the salivary amylase enzyme, AMY1A gene copy number, and the ancestral starch consumption in Homo Sapiens (Tracey 2017, p.22). It was hypothesized that the relative amount of starch consumption was very high for my personal ancestral diet, thus my AMY1 diploid gene copy number in my genome and salivary amylase concentration would be significantly higher than the population mean. With a population of 28 subjects (n=28), individual saliva samples were collected and compared to a calibration curve to determine the approximate amylase concentration by analyzing absorbance values. Individual samples of buccal cheek cells were

Cells in all living things have an outer layer known as the cell membrane. The structure of the cell membrane consists of the phospholipid bilayer organized by the arrangement of hydrophilic heads and hydrophobic tails. It is a selectively permeable membrane, where it divides the outer environment from the interior of the cell. It can control substances moving in and out of living cells. Certain molecules like gases, water, and food are permitted to pass the membrane through the method of diffusion. Diffusion refers to the process in which molecules move on the concentration gradient, where they move from an area of high concentration to an area of low concentration. A type of diffusion is known as osmosis. It is the diffusion of water moving across the selectively permeable membrane. In this lab, students will be using eggs to construct an experiment to get a better study on how osmosis works in a cell. The eggs will be soaked in vinegar solution to remove their shells to expose each inner layer that resembles a selectively permeable membrane. The egg shell is composed of calcium carbonate that would dissolves in acidic solution such as vinegar. In the chemical reaction, it releases carbon dioxide gas. After the removal of the egg shell, it will be ready to be able to construct the experiment.

In conclusion, the data that was collected helped tell us that the solutions greatly affected the cell of the egg because it caused the egg’s mass to increase than decrease. Also saw how the solutions played a role in the phospholipid bilayer and saw how it altered the shape of the egg. However, it does not support my hypothesis on the affect the egg would undergo onced placed in sugar and water but sugar was not used in this experiment, but water was used and it didn’t affect the shape of the egg, all it did was cause the egg to be in a isotonic state. According to Khan Academy (2017), states that a cell is isotonic “When the extracellular fluid has the same osmolarity as the cell, there will be no net movement in or out of the cell”. Which

The evidence that was collected in the experiment refuted the day one hypothesis because after the egg soaked in vinegar for 72 hours, the mass of the egg was not the same, it was greater than before. The day two hypothesis was also refuted because after the egg soaked in maple syrup for 48 hours, the mass of the egg was not greater, it was less than before. The evidence collected accepted the day three hypothesis because after soaking in deionized water for 24 hours, the mass of the egg became greater than

An egg has a semi-permeable membrane, thus processes like osmosis could occur. Osmosis is the movement of water molecules from an area of higher water concentration to an area of a lower water concentration. Osmosis is important, especially for living organisms, as they help distribute nutrients in the body. An egg’s mass would change when it is soaked in different substances. The goal of this experiment was to investigate how an egg changes through osmosis. This experiment was done to show how substances affect the mass of an egg. To start off, an egg’s mass was measured by putting the egg in a beaker then placing it on a mass scale. The beaker was then filled with vinegar and left alone for twenty-four hours. After a day, the egg was taken

Videos of proper dissection of the organisms were studied prior to the dissections to prevent any unnecessary damage to the organisms that could lead to errors in our data. For each organism, a scalpel was used to pierce the skin and a pair of scissors was used to open up the organism. If the organism had several layers of skin (i.e. the bullfrog and perch), then forceps and a scalpel were used relieve the tension and peel the layers away from the organs or the chest cavity. Once the external layers of the organisms were cut away from the organs, those layer were pinned back with dissection pins to assure the stability of organism and clarity of the dissection. The unneeded organs were cut out and discarded while important organs, those in

Introduction: Osmosis is the movement of water from a less concentrated solution to a more concentrated solution through a semipermeable membrane because it is active transport, thus going against the concentration gradient.1 This process was initially thoroughly studied 1877 by German plant physiologist, Wilhelm Pfeffer.2. For Osmosis to occur, it requires two solutions with different concentrations and a partially permeable membrane to separate them. Since the water diffuses towards the more concentrated side of the membrane, the concentration of the more concentrated side will continue to rise, which while the one on the less concentrated side falls. However if the concentration of both sides of the semi-permeable membrane are equal in

Turns out dads are also eating for two. A study published December 3 in Cell Metabolism reveals that a man's weight affects the heritable information contained in sperm. The sperm cells of lean and obese men possess different epigenetic marks, notable at gene regions associated with the control of appetite. In his study, the researchers compared specific epigenetic marks in the ejaculate of lean and obese men (men were the focus because sperm is much easier to obtain than eggs). While no differences were seen in the proteins that wrap up DNA, there were variations between the participants' small RNAs (for which the function is not yet determined) as well as methylation of genes associated with brain development and appetite. The next question was whether these differences were byproducts of obesity or lifestyle, which yielded the look at how bariatric surgery affects sperm epigenetics and discovery that weight is the main factor.

During this lab dissection I hope to gain a better understanding of how the different organ systems inside of a chicken work together. I expect to do well with this dissection because I have performed numerous necropsies with Dr. Macklin while working in his poultry microbiology lab. Many different components will factor into how much excitement or fear I will have heading into the lab. My excitement for this lab will come from learning how everything works together, and my fear will be not knowing which part of the chicken to dissect because I do not remember the correct anatomical terminology that we will use.
