Europe. The second factor of overeating may be caused by boredom. Sometimes people eat because they have nothing to do. It is very easy to turn on the TV‚ take a lot of snacks‚ lie down on a couch and watch TV. That is why we have expression couch potato. I think that the eating is a form of entertainment for many people. What a habit! According to my opinion‚ population has become lazier and than ever. And last but not least‚ is very easy access to food than before. Just imagine how many opportunities

Osmosis investigation Aim: To investigate how sugar concentration affects the mass or size of a potato and find out the sugar solution. Introduction: Osmosis is the movement of water molecules across a partially permeable membrane form a region of high water concentration to a region of low water concentration until the concentration on both sides is equal. This means that osmosis is like diffusion involving water molecules. Osmosis occurs across a partially permeable membrane‚ with holes

The Process of Osmosis and its Importance to Living Organisms. Osmosis is the diffusion of water through a semipermeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only to diffusion of water and the direction of movement is from the area of higher concentration to the area of lower concentration. This migration of water from a region of higher concentration to a region of lower concentration is spontaneous and although water molecules move in both directions

Osmosis is movement of H2O molecules passing through a permeable cell membrane to the less concentrated solution‚ eventually to reach an equivalent number of molecules on both sides of the cell membrane. 1.2 The important factors in the process of diffusion and osmosis is H2O being present with soluble molecules that are small enough to be absorbed through the cell membrane to then

Observing osmosis‚ plasmoylsis and turgor in plant cells Investigation * Get a single layer of plant cells. If you are using red onion‚ cut a 1 cm square from a fleshy piece of onion and then peel off a single layer of the red cells. If you are using rhubarb‚ peel a piece from the epidermis. If you are using toadflax peel a piece of the lower epidermis of a leaf. * Place the strip on a slide and cover it with a drop or two of distilled water. Add a cover slip. * Look at the cells through

The effect of salt concentrations on the mass of the pear cubes ‘Pyrus’ after being soaked in water Aim: The effect of salt concentrations on the mass of the pear ‘Pyrus’ pieces shaped as cubes of 1cm. Background: Osmosis is the net movement of water molecules through a semi-permeable membrane from an area of higher water potential to an area of lower water potential. Water makes up to 70-90% of living cells and cell membranes are partially permeable membranes. Dissolved substances attract

1) Irish Potato Famine. 1845-1849. Called the Great Famine. In the early 19th century‚ Ireland’s tenant farmers struggled to provide for themselves and to supply the British market with cereal crops. By the early 1840s half the Irish population‚ mostly the rural poor‚ became to depend almost exclusively on the potato for their diet. The rest of the population also consumed it in large quantities. A heavy reliance on just one or two high-yielding types of potato greatly reduced the
