Concentration of a Potato Aim: In this investigation I am going to work out the sugar concentration of a potato. I aim to find this out by putting potato cores into various concentrations‚ measuring the mass before and after. Due to osmosis the potato cores will change in mass to make the concentrations at an isotonic level‚ helping us to work out the mass of the potato. I predict that potato in the weaker solutions will gain mass‚ because some water will be absorbed by the potato to make the concentrations

pineapple’s skin extract on Candida albicans. Instruments The researchers will use Candida albicans that they will buy from University of the Philippines Los Baños (UPLB). The fungus‚ then‚ will be divided into three setups: Set A‚ Set B‚ and Set C. Each set will contain Candida albicans placed in a Petri dish. These sets will be given different amounts of the Pineapple skin’s soap extract; Set A will be given 40%‚ Set B will be given 70% and Set C will be given 90% of the soap extract. The researchers

There are many things that were‚ are and are very likely to stay incomprehensible for us therefore causing perpetual anguished reflections and arguments for many generations of people. Some of these things are objective‚ natural phenomena in the world around us like the blue colour of the sky or the instinct of different birds and fish which always leads them home. But also there are such things like Good and Evil‚ Love and Hatred‚ Honesty and Betrayal‚ Self-sacrifice and Egoism‚ Eternity and Transiency

Mortality Rate of Termites Sprayed With Yemane Decoction and Chili Extract Chapter 1 – Introduction Background of the Study Using natural pest and disease control is often cheaper than applying chemical pesticides because products and materials which are already in the home and around the farm are most often used. Termites are small‚ white‚ tan or black insects. It belongs to the insect order Isoptera‚ an ancient insect group that dates back more than 100 million years. Termites also

OSMOSIS Aim To determine the water potential of potato tuber cells. Background knowledge Osmosis is defined as the movement of water molecules from a region of higher water potential to a region of lower water potential through a partially permeable membrane. Osmosis is considered in terms of water potential and solute potential. Water potential is a measure of the kinetic energy of water molecules. Here‚ water molecules are constantly moving in a random fashion. Some of them collides with cell

Poem Comparison The Prelude and Below the Green Corrie In ‘Extract from The Prelude’‚ William Wordsworth attempts to explore and understand how his perception of nature and the world in general has been influenced by an event in which he ‘found a small boat tied to a willow tree’. At first rowing confidently upon the loch‚ the sight of a mountain peak from behind a ‘craggy steep’ scares him and he races back to safety where he returns home in a ‘serious and grave mood’. This memory haunts him in
