______ 1. Background: Potato is a starchy‚ tuberous crop from the perennial “Solanum tuberosum” of the Solanaceae family (also known as the nightshades). It originated from the area of present-day southern Peru and it’s now grown worldwide. Potatoes were first introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world ’s cuisine. It is the world ’s fourth-largest food crop‚ following rice‚ wheat‚ and maize. Wild potato species occur throughout

Potato Battery Chapter I: Introduction I. Background of the Study Do you have like 500 unused sacks of potatoes and don’t know what to do with it? Does your low class battery always die out on you at the exact moment you look at the last digit of you clock? If you answered yes‚ then here is the solution to your problem! Potato batteries are designed for you! So why do you spend so much money in buying new batteries for your digital clock if you can use the alternative resource. II. Statement

POTATO BATTERY Abstract a. Purpose To lessen the consume of electric charge b. Procedure We insert copper and zinc electrodes in to the potato‚ close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we removed the shell of a broken AA battery for our Zinc electrode. (Make sure to test your multimeter by connecting its Positive and Negative

those in the province‚ the researcher came up with the study entitled “Potato Battery”. Two new sources are fruits and vegetables. These are organic and can easily be bought at farms and markets. One of these is the use of potato but not all fruits and vegetables are usable. Potato had been considered due to it’s high content of phosphoric acid. B. Statement of the problem This study basically aims to find out whether a potato could be able to produce enough power to light up a bulb. And if it

Osmosis in Potato Tubers Andrew Dickson Background When a plant cell is bathed in a solution of the same concentration (isotonic) as its intracellular environment‚ its mass and volume remain the same. This is because water enters and leaves the cells at the same rate. There is no net loss or gain of water by osmosis. Samples of cells can be placed in a range of solutions of different concentration. The cells will gain water by osmosis when placed in solutions which are more dilute (hypotonic)

to die? Hypothesis: If the sailor drank the 40% salt water solution‚ then would die sooner‚ because the high amount of salt causes more dehydration. Variables: Independent- Salt Solution Dependent- Mass of Potato Control- Tap Water Materials: •Tap Water (50 ml for each cup) •Salt •Beaker •3 cups •3 pieces of potato •Scale Procedure: Step 1: Gather Materials. Step 2: Weigh each potato separately on the scale and record weight in grams on table. Step 3: Put each potato in a separate

Effect of Osmosis on Potato Aim: To investigate the effect osmosis has on potato pieces that are placed in different concentrations of sugar solutions in water. Hypothesis: I believe that the more saturated the solution is the lighter the potato will be‚ and the potato in the clear water will weigh more after being left in the solution over a 24 hour period. This is because the cell membranes in the potato act as semi permeable membranes (meaning that they only allow certain molecules through)

Since potato cells were used for this type of experiment‚ in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl. In other words‚ water moves in and out in the same amount without causing any changes. In a hypertonic environment‚ the solute concentration is greater and water concentration is less outside the potato cell in which the hypertonic solution contains 10.0% NaCl. This solution will cause the potato cells

The “Couch Potato” Lifestyle “Couch potato”‚ a slang term to describe a person who spends most of the time sitting or lying on a couch. However‚ sedentary lifestyle is another term which commonly used as a medical term to describe a lifestyle with irregular psychical activities or exercise.
