there is a concentration gradient across the membrane‚ water will move across the membrane down the concentration gradient while the salt cannot. If there is more salt and less water inside a cell than outside‚ water will flow into the cell from the surrounding environment. This process is called osmosis. When the environment outside a cell has a lower concentration of dissolved molecules than inside the cell‚ the solution is hypotonic‚ and water will move from the solution into the cell. If the surrounding

Next to oxygen‚ water is the second most crucial necessity of human life. Up to 60% of the human adult body is water (Perlman). Human blood is made up of ninety-two percent water (Sanders). The relevance of ingesting water is the cause for a debate about which source is the best‚ bottled water or tap. There are several reasons to choose bottled water over tap water when quenching thirst. One reason to choose bottled water rather than tap water is because bottled water is odor free. Occasionally

Tap Water vs. Bottled Water "The U.S. public goes through about 50 billion water bottles a year‚ and most of those plastic bottles are not recycled" (Karlstrom‚ Solvie‚ and Christine Dell’Amore). Bottled water is harming our environment in many ways. Small things such as transporting these bottles set off fossil fuels which pollutes the air. This could have a huge impact on our environment in the long run. Tap water is more efficient and healthier for our environment‚ instead of bottled water. Bottled

Which water is better to drink tap water or bottle water? That question is very common now days. Water is an essential part of human life. Whatever top water or bottled water‚ we need to drink at least 8 glasses of water per day to make sure we are healthy and everything run correctly‚ but the principal disagreement is that most people prefer to drink bottled water than tap water. Most of us would agree that the argument for drinking bottled water is basically the flavor and there are those who

The Growth in Potato Production and Inception of Secondary Potato Markets in India Case Study: McCain India Limited Potatoes are a staple food crop in most developed and developing nations. The original habitat of South America was discovered by Europeans when Columbus landed on Latin American soil. However‚ the potato was adapted as a field crop only during the late 16th and early 17th century1. Global

Osmosis in Potato Conclusion The data we had did not support the definition of Osmosis‚ Osmosis is the diffusion of water through a partially permeable membrane from a region of lower solute concentration to a region of higher solute concentration; the data we collected did not seem to fit into this. The potato chips were suppose to lose more mass in the higher concentrated solution as the water from the potato chip will flow out to the higher concentrated solution as the water inside the potato has a

enzyme breaks H2O2 into water and oxygen. The production of the oxygen gas bubbles serves as evidence that the catalase enzyme is working. As catalase is breaking the bonds between H2O2‚ it is releasing energy in the form of heat which is reason for the warmth of the bubbles during the reaction. Starch acts to trap these bubbles and this creates a relatively stable foam that can be measured. ANALYSIS QUESTIONS 1. a) Describe the effect of damaging the potato on the catalase activity

movement of water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel down its concentration gradient‚ which was from a higher concentration (in the cell) to a lower concentration (in the solution)‚ which meant the potato cells lost
