shallow layer of solvent and sealed. As the solvent rises through the paper‚ it meets the sample mixture‚ which starts to travel up the paper with the solvent. This paper is made of cellulose‚ a polar substance‚ and the compounds within the mixture travel farther if they are non-polar. More polar substances bond with the cellulose paper more quickly‚ and therefore do not travel as far. Hypothesis The same color candies will have the same colored dyes which are used in making the candy. For example‚ the

are the cells that are involved with the transport of water. Fibres are elongated with lignified walls that help to support the plant. They are dead cells; they have no living contents at all. Parenchyma cells are plant cells they have unthickened cellulose cell walls and contain all the organelles you would expect to see. However the parenchyma cells in xylem tissue do not usually have chloroplasts as they are not exposed to light. They can vary in shape‚ however most of them are isodiametric that

Chapter II Review of Related Literature and Studies Related Literature According to Wikepedia Book‚ Ink is a liquid or paste that contains pigments or dyes and is used to color a surface to produce an image‚ text‚ or design. Ink is used for drawing or writing with a pen‚ brush‚ or quill. Thicker inks‚ in paste form‚ are used extensively in letterpress and lithographic printing. Ink can be a complex medium‚ composed of solvents‚ pigments‚ dyes‚ resins‚ lubricants‚ solubilizers

Termites are a group of eusocial insects that‚ until recently‚ were classified at the taxonomic rank of order Isoptera‚ but are now accepted as the infraorder Isoptera‚ of the cockroach order Blattodea. While termites are commonly known‚ especially in Australia‚ as "white ants"‚ they are for practical purposes unrelated to the ants. Like ants‚ and some bees and wasps—which are all placed in the separate order Hymenoptera—termites divide labor among castes‚ produce overlapping generations and take

I am all for finding a new way to produce biofuels. today scientist can do this by finding a gene that breaks up cellulose‚ the substance that makes up most of the plant matter and the most abundant organic molecule on Earth. Scientist can do this instead of producing biofuels from corn kernels. Instead of eliminating our food for fuel‚ we can manipulate a gene to break down cellulose. This way the biofuels are made and we are not killing our natural resource. California right now is trying to

December 13‚ 2009 Growth Potential for Biofuels 2 Executive Summary This paper will discuss the history and growth potential for biofuels as a way to relieve our dependence on foreign oil in the United States. It will look at the different sources available to produce biofuels‚ and whether biofuels would actually result in a reduction of green house gases. Lastly‚ I will discuss

carbohydrates formed by combination or chain of monosaccharides and are a very common organic compound found in nature. We are exposed to them various times a day and they make up an important part of our Earth. Some common polysaccharides are: cellulose‚ chitin (in seafood)‚ starch‚ alginate‚ hydroaluronic acid‚ chondritin sulfate‚ glycogen‚ xylan‚ pectin‚ and various others. Polysaccharides boast varied and mostly useful properties that vary based on their structure‚ on of the most important being

Water is the most important substance in our evolution and our daily lives. Without water‚ life as we know it would not have been possible. This essay will examine the water molecule in order to ascertain how it brought about Earth ’s thriving ecosystem and how important it is to us today. Each water molecule consists of one oxygen atom and two hydrogen atoms. The oxygen atom (or the apex of the water molecule) bears a slight electronegative charge while hydrogen possesses a more positive
