active transport requires the cell to use energy. Diffusion is the simplest form of passive transport. Using its own energy molecule will move from areas of higher solute concentrations to areas of lower concentrations until a balance is reached. Osmosis is also a form of passive transport.Osmosis occurs when water molecules diffuse across the cell membrane from an area of higher solute concentration to an area of lower solute concentration. There are three relative concentrations of solutions.

The Egg Drop Analysis 1. As far as researching goes I did not do many research besides videos I mainly saw a lot of sponges or big sponges use for people experiment and I in fact went with it and prototypes I used were mainly the same thing with some added cushion to it. 2. I forgot to take a picture but a good description would definitely be a can and thats wrap in cushion on the inside and the outside but the error I made was not covering the metal shock that will it takes impact it release

Egg flotation Objective/Question/Problem My objective is to see which egg will float. The question is how much salt is needed to be added to make the egg float. The problem is that I do not know how much salt is needed to make an egg float. Hypothesis If I add salt to the water then the egg will float because the egg has a density that is lower that the density of the fluid it displaces. Background Information If the object has a density that is higher than

Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which

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

The painting Broken eggs was created by Jean-Baptise Greuze in 1760 and suggests the beginning of the different direction in the art of painting. His work‚ free of fantasy‚ introduces new realism – the realism of daily life. French painting during 18th century was dominated by the Rococo style that was aristocratic in nature‚ sensual and elegant. From stylistic point of view‚ it had soft colors in its palette‚ free brushstrokes and complex surfaces. Created for rich patrons‚ Rococo concentrated on

Chinua Achebe’s short story "The sacrificial Egg" illustrates the life of a young African native Julius Obi‚ and the arising conflicts between two cultures. This short story takes place in a very small village in Africa‚ called Umuru in the mid 1900’s. This young African Native‚ although no native of Umuru finds himself trapped between his own culture‚ beliefs and the westernized culture. Although Julius has embraced the western culture‚ after certain events he eventually finds himself coming back

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
