of a different solution to each test tube. After that‚ we added 3 drops of iodine to each solution. Finally‚ we jotted down the results and colors of each tube. The experimental group is 5mL of each of these solutions: onion juice‚ potato juice‚ sucrose‚ glucose‚ distilled water‚ reducing sugar‚ and starch. There is no control group because all the solutions are being experimented on. Iodine is the independent variable because you control how many drops of iodine are put in each solution‚ while the

The phloem consists of living cells arranged end to end. Unlike xylem‚ phloem vessels contain cytoplasm‚ and this goes through holes from one cell to the next. Phloem transports sucrose and amino acids up and down the plant. This is called translocation. In general‚ this happens between where these substances are made and where they are used or stored. It is also interesting to note that plants have pores‚ called stomata‚ on the

“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

What are the central ideas of Cells? • What are cells? – Cells are the smallest basic unit of living things. • What do they do? – Cells take in raw materials and making new substances. • Why do they do this? – In cells‚ organelles carry out activities to keep the organism alive. – E.g. synthesising proteins and fats‚ releasing energy from glucose. What are the central ideas of Movement of Substances? • What processes describe how substances move from one region to another? –

something that has made a huge difference in people’s lives is the water filtration system(s). NASA first made it to be used on the space station or in a spacecraft‚ and since then the water filtration system is a must-have in any place in the world. NASA showed amazing ingenuity to control bacterial contamination in space‚ and because of that‚ we have learned how to control pollutants in water here on earth. We see water filtration systems more than we think‚ and it allows us to enjoy a healthy lifestyle
