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 drug I chose for this are bath salts. The reason why I chose this drug is because I want to learn more about its effects and potential dangers.

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

In the article‚ " The Egg and the Sperm" by Emily Martin‚ the author attempts to shed light on the gender stereotypes hidden within the scientific language of our biology textbooks.

I had no idea that within the scientific accounts of reproductive biology
