out of cooked beetroot? Introduction When cooking a beetroot you are recommended not to remove the outer skin and not to cut off the entire stalk if you do not want the red dye in the cooking water. Beetroot contains a red pigment called betalain‚ which is in the cell vacuole. Normally the betalain stays inside the cell‚ however when the cell is exposed to extreme temperatures they leak out. The reason why they leak out is because of the cell membrane structure. When the cell membrane is exposed

Maria Montessori Practical life activities give the child an understanding of his/her environment and how it works. The child enjoys all types of work. Child also enjoys keeping the environment beautiful for all to use. This work builds the child’s self-esteem‚ making him feel of value. It may seem like they are "playing" when they are table scrubbing or polishing silver‚ but through these types of activities they are becoming prepared to do the "real" learning. Practical Life activities also

Energetics Practical 2: To Determine the Enthalpy Change of a Reaction Background Calcium Carbonate‚ CaCO₃‚ decomposes with heat to form CaO and CO₂. The objective of this practical was to determine the enthalpy change for this reaction by using an indirect method based upon the foundation of Hess’ Law. Both calcium oxide and calcium carbonate react readily with 2 mol/dm3. The reaction can be demonstrated as so: CaCO₃ (s) -> CaO(s) + CO₂ (g) Results: Raw Data Calcium Carbonate Mass of CaCO₃

independent. Therefore‚ the first active manifestation of the child’s individual liberty must be so guided that through the activity he may arrive at independence. * Dr. Maria Montessori Comment on the above quote and explain how the Montessori practical life exercises help the child to become independent. “No one can be free unless he is independent. Therefore‚ the first active manifestations of the child’s individual liberty must be so guided that through this activity he may arrive at independence

Depending on the cancer that one may have cancer cells have more chromosomes that are scattered which is for why cancer cells are formed. In cell division all living things obtain cells in which come from other preexisting cells. If normal cells are do not divide and make new cells then cancer will occur. In order of all cells to be

CORE PRACTICAL ONE Describe how the effect of caffeine on heart rate in Daphnia can be investigated practically‚ and discuss whether there are ethical issues in the use of invertebrates. Daphnia‚ the water flea‚ is a small freshwater crustacean which lacks physiological methods of maintaining a constant body temperature. This means that if the environmental temperature changes‚ its body temperature does so too and its metabolic rate will be expected to rise or fall accordingly. So the temperature
