Egg Lab

to determine and understand what circumstances materials will convey across the membrane of an egg”. Furthermore, the egg was placed into three differing solutions, maple syrup, tap dihydrogen monoxide, and brine, to illustrate that “depending upon the concentration of dihydrogen monoxide in an egg and that in its circumventing environment, dihydrogen monoxide may diffuse into or out of the egg”. In summation, to genuinely understand the lab and make a plausible prognostication one must first grasp the concepts of the cell membrane as a semi-permeable barrier and the kineticism of dihydrogen monoxide.
Cell membranes are semipermeable, denoting the membrane is a barrier to most, but not all molecules. Semi-permeability dissevered and bulwarks
the cell’s inner environment from the cell’s external environment. Examinations of cell membranes have led to the development of the lipid bilayer model. The most prevalent molecule in the model is a phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails. Since aligned tail to tail, the hydrophilic heads are located on the inner and outer surfaces of the membrane.
Dihydrogen monoxide is one of the few simple molecules that can cross the phospholipid bilayer by diffusion, concretely osmosis. Osmosis is the diffusion of dihydrogen monoxide across a semipermeable membrane. However, the presence of a solute decreases the dihydrogen monoxide potential of a substance; in example, there is more dihydrogen monoxide per unit of volume in a glass of fresh-dihydrogen monoxide than there is in an equipollent volume of sea-dihydrogen monoxide. This point is responsible for two hypotheses, concerning the maple syrup solution and the tap dihydrogen monoxide solution. The projected hypothesis concerning the maple syrup solution was that the solution would be hypertonic. This projection was initially made through deduction. Syrup is a highly viscous solution in comparison to dihydrogen monoxide; however, it is mundane erudition that syrup contains dihydrogen monoxide. Most living organisms are virtually entirely composed of dihydrogen monoxide, such as humans, so it was surmised chickens were equipollent. Hence, it was deduced that there would be more dihydrogen monoxide in the egg, than in the syrup-making the maple syrup hypertonic. Dihydrogen monoxide diffuses through the process of
osmosis, involving a gradient of high to low concentration, denoting dihydrogen monoxide would pass through the egg’s membrane to move into the syrup solution.
Hence, it would result in the egg losing mass. Crystal Hill Bio 101-Petty The second hypothesis concerned the egg in the tap dihydrogen monoxide. The logic abaft the hypothesis emanated from the phrenic conception sequence that tap dihydrogen monoxide is entirely dihydrogen monoxide, and the minerals found inside are negligible. Albeit the chicken egg is mostly dihydrogen monoxide, “mostly” dihydrogen monoxide is not “entirely” dihydrogen monoxide. So, it was sooth said that tap dihydrogen monoxide would hypotonic in cognition to the egg, and the egg would gain mass from dihydrogen monoxide being passed into the egg. Additionally, dihydrogen monoxide has the propensity to peregrinate from an area of higher
concentration to one of lower concentration. In essence, dihydrogen monoxide molecules move according to differences in potential energy between where they are and where they are going. This point is categorically responsible for the hypothesis concerning brine, in cognition to the egg. Even though salt is utilized as preservative in alignment, it preserves pabulum by drawing out moisture, designating it has a more preponderant energy than most molecules responsible for moisture in pabulum-concretely dihydrogen monoxide. Hence, it was surmised that saltwater would prove to be hypertonic, in comparison to egg....
