Abstract The experiment was carried out to investigate at which point the potato has reached its isotonic environment. From the results‚ when the concentration increase to 0.3M‚ the mass of the potato slices decreased by -3.26%. We can conclude we see that as we increased the sucrose concentration it was a decrease in the percent change. Introduction All cells have membranes that are selectively permeable. In other words‚ they allow certain things in and certain substances are not allowed to

The Micro Chip Computer Corporation Shows a total of net sales for the years of 2000 – 2004. The total net sales have seemed to drop since 2000. I will compute the year-to-year percentage annual growth in total net sales by taking the current year total net sales and subtracting the previous years. I will then multiply that by 100 and then divide that by the previous year’s total net sales. This will give me the annual percentage growth. The formula will be (current year total net sales – previous

area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are very tiny and can only be seen with a microscope‚ so you are going to use sticks of potato tissue in solutions that have different concentrations of dissolved substances to observe the effects of osmosis on living tissue. There are three basic relative concentrations of solutions. An isotonic solution has a concentration of dissolved particles

The third plastic beaker contained 8 mL of water. Using the first and second beaker the experimental assay was performed. Using forceps a small paper disk was dipped into the second beaker containing the potato catalase for exactly 5 seconds. It was next dried on a paper towel for 5 seconds‚ and finally placed at the

ARTIFICIAL INTELLIGENCE: BRAIN CHIPS When you think about Artificial Intelligence what thought first comes to mind. Robots maybe‚ would we ever think about Brain Chips being implanted into human brains? Sure‚ but how will Brain Chips plays a major role medically in are world’s future? In are near future‚ while we sleep they will transmit data directly from are brain to the computer and not miss a wink of sleep. Computer Interface is only the tip of the iceberg.

When the Irish Potato Famine Struck Ireland On a sunny morning in 1845‚ Irish farmers were going to check their crops. A farmer named Abraham Fitz found black potatoes in his fields. He thought it may be only the one‚ so he moved over 4 rows and dug another potato out of the ground. This one was black and rotten. This causes Abraham to travel to his neighbors house and ask about their potatoes. His neighbor’s potatoes were black‚ rotten‚ and giving off a foul stench. This would later be discovered

cell‚ so the water molecules diffused out of the cell through the selectively permeable membrane. The higher the concentration‚ the more plasmolysed the cell becomes and my results show this. The 0M bathing solutions in both experiments caused the potato cells to become slightly turgid‚ this means that there was a higher concentration of solution on the inside of the cell. So the water molecules diffused into the cell through the selectively permeable membrane. The rate of water loss decreases as
