1. EGG INOCULATION The fertile hen’s egg can be used to cultivate and propagate various types of viruses. Because of the ability to alter their tropism and to adapt to a new host species‚ many viruses become capable of growing in chick embryo tissues wherein they frequently attain a much higher concentration than in the tissues of the natural host. STRUCTURE OF AN EGG The extra-embryonic membranes of the chick embryo arise from three germinal layers: the endoderm‚ mesoderm and ectoderm

Title : Osmosis in Quail’s Eggs Research Question What is the effect of different concentrations of sodium Chloride (NaCl) on the mass of the de-shelled quail’s eggs? Introduction Osmosis is an example of passive transport. Osmosis is defined as the movement of water molecules‚ down its concentration gradient‚ from an area of high water concentration (low solute concentration) to an area of lower water concentration (high solute concentration) through a selectively permeable membrane. Osmosis

Rhonda Anderson 10 August 2011 Title: Creating the chemical reaction of Osmosis with an Egg. Purpose: We are taking a large single cell (the egg) and demonstrating Osmosis. Osmosis is a type of diffusion where the water molecules is the solution that is being moved. Osmosis is the movement of water through a semi-permeable membrane. Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. Introduction: When trying to create

of our project was to design and build a contraption that would secure an egg from breaking upon impact from a second story window‚ and the contraption wieghing as least as possible while falling the fastest. We wanted to design something that would provide a lot of cushioning directly to the egg‚ and also provide extra cushioning to weaken the impact. After testing and submitting a design of just bubble wrap around the egg we found out that it will not be allowed. Due to this we had to make changes

The Sperm and Egg Testes are suspended outside the abdominal cavity by the scrotum‚ a pouch of skin that keeps the testes close or far from the body at an optimal temperature for sperm development. Somniferous tubules are inside each testis‚ and are where sperm are produced by meiosis. About 250 meters (850 feet) of tubules are packed into each testis. Spermatocytes inside the tubules divide by meiosis to produce spermatids that in turn develop into mature sperm. Sperm production

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
