Osmosis of a Potato cell. Hypothesis is that the potato in saltwater is going to show that it will break down the cells of the potato. Osmosis is the diffusion of a solvent through a semi-permeable membrane‚ from a solution of low solute concentration to a solution with high solute concentration‚ up a solute concentration gradient. Net movement of solvent is from the less-concentrated to the more-concentreated.‚ which tends to redure the difference in concentrations. This effect can be countered

Within a matter of weeks it will be Easter time. Eggs will not only be hidden for little children to find but an egg is a symbol of life. Eggs are often the prime example used in a Christian Sunday school to visually explain the Resurrection of Jesus. The eggs shell represents the stone that separated his tomb from the outdoors. When the hard shell barrier cracks‚ or in this case when the stone is rolled away‚ life comes into the world. In the Etruscan tomb of the Lioness lays a Banquet scene fresco

The Human Egg Cell. The human egg cell is also known as the ovum. With a spherical structure it is the largest cell in the human body measuring about 0.2mm in diameter. The function of the ovum is to reproduce‚ when fertilized by the sperm cell the ovum is capable of creating a new living organism. The size and shape of the ovum gives it space to store and create nutrients (see fig 3) (Boyle and Senior 2008) The ovum is bounded by the egg follicles of the ovaries and is produced by primitive germ

OSMOSIS IN POTATO TISSUES Vanessa Tsao‚ Lovette To‚ Wang Yeyun‚ Zhang Shenjia‚ Alicia Mak Class 101‚ Nanyang Girls’ High School‚ 2 Linden Drive‚ Singapore 288683 ABSTRACT In this project‚ the relationship between the concentration of salt solution and the length of the potato strip that was immersed in it was investigated. Five strips of potato of the same length were placed in different Petri dishes that contained water of different salt concentration. They were left for twenty minutes and the length

Eggs are fried in cooking oil‚ sometimes with a sprinkle of salt. It is common to put a fried egg on top of bibimbap or Kimchi bokkeumbap. Sometimes‚ rice dishes‚ such as bokkeumbap‚ are simply made by applying a fried egg on a top of a bowl of hot rice‚ drizzled with a spoonful of gochujang and sesame oil. Occasionally‚ salt is added to fried eggs‚ and served as Banchan‚ which refers to small dishes of food served along with bap. Fried eggs can be served on toast‚ or in a sandwich‚ with bacon

Investigating the effect of different concentrations of glucose on the percent change in mass of Gummy bears according to their respective colours In this experiment osmosis is the main process taking place. Osmosis is the diffusion of water molecules of a solvent which pass through a semi permeable layer and in most cases are due to a concentration gradient meaning that the water molecules travel from an area of low concentration to one of higher concentration. In this investigation‚ gummy bears

The Bouncy Egg Experiment! Mrs. Murosky December 19‚ 2013 Introduction: GOAL: The goal of this experiment is to get an egg to bounce. WHY IS THIS IMPORTANT? : The results of the egg experiment is important because it shows what the membrane of an egg looks like‚ but allows the experimenter to have fun in the process. LITERATURE: The acids in the vinegar make the shell deteriorate. Eggs contain "calcium carbonate"(this is what makes it hard)‚ and vinegar is an acid. When they both combine

How much salt must be added to a glass of water for an egg to float? Hypothesis: I believe it will take 5 tbsp. of salt to be added to water for an egg to float. My reason is that I think that 5 tbsp. of salt is very heavy and will make the water heavy enough to float the egg. I must make the water heavy enough to float the egg. If the water has enough salt it will float. Materials Used: Eggs – 2 medium sized chicken eggs (2.0oz each) Natural Sea Salt Iodized Salt (table salt)

This egg drop experiment forced me to think and develop a design that I felt confident with. I developed several models and tested them numerous times‚ but could not settle on one. Eventually‚ I was able to put an addition onto one of my designs which gave me confidence in its ability to protect that precious egg. I will explain why my design worked so well in respect to impulse‚ air resistance‚ and stability. First‚ I will discuss impulse. Impulse is a force acting briefly on a body and producing
