If the pH level of the solution is more basic‚ then the potato membrane will weigh less due to osmosis. Our null hypothesis was: If the pH level of a solution is either acidic or basic‚ then it will have no effect on the weight. The independent variable was the different solutions of different pH values. The dependent variable was the weight of the potato‚ which was measured in grams. The baseline of this experiment is the weight of the potato when in the milk solution because milk has a neutral pH

In 1990‚ from a residence in Manila‚ Epifania de Jesus put up a small sari – sari store which is retailing goods and soft drinks. Eventually‚ their store became bigger with the help of her husband; and in 1998 they expanded the store from retailing to a wholesaler soft drinks store and named it “Funny Kids”.

from which I should be able to draw a firm conclusion that will either prove or disprove any predictions I make. This essay aims to assess and investigate the effect of various solution concentrations on the activity of osmosis in plant tissue. Background scientific theory: Plants exchange gases (CO2 and O2) in maintaining vital respiratory processes and in carrying out photosynthesis; they absorb certain minerals and sugars so to use as a source of energy and eradicate wastes in order to maintain

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

Batteries contain heavy metal such as mercury‚ cadmium and nickel which can contaminate the environment when batteries are improperly disposed of. When flamed‚ certain metals might be release to the air or be left in the ash of the burnt battery. By draining and neutralising acid from the batteries and recycling them our problem is solved. The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before

Summary The poem begins with our speaker at his desk‚ his pen poised to begin writing. He gets distracted by the sound of his father outside‚ working in the garden‚ and this sends our speaker into a spiral of memories about his father working in the potato fields when the speaker was a young boy. The memory stretches even further back to his grandfather and the hard work he did as a peat harvester (there’s all kinds of hard work going on). Eventually‚ our speaker snaps out of his daydream‚ and we find
