... by moving the bulb further and further away from the plant. Plants need light energy in order to make food. The more light they have the faster they can make food. Again there is a limit. Making the light very ...

... yet they require oxygen to respire, and as water is such a good solvent the required oxygen gas is dissolved in the water. Water is the most abundant component in any organism, the lowest is 20% in seeds, while ...

... dioxide into glucose and oxygen. Both animals and plants for respiration use oxygen produced by photosynthesis. The word equation for photosynthesis is: Carbon dioxide + Water Glucose + Oxygen The balanced chemical equation for photosynthesis is: 6CO2 + 6H2O C6H1206 + 6O2 A water ...

... By comparing the Rf values of the components of a particular mixture with the Rf values of a known substance under identical conditions, the compounds present in a mixture can be identified. AIM: to compare and analyse the colors and ...

... stronger attraction for these shared electrons than the comparatively tiny hydrogen nuclei. This pulls the electrons slightly closer to the oxygen nucleus and away from the hydrogen so that the oxygen develops a slight negative charge and the hydrogen's a ...

... molecular mass). This means that it has a high specific heat capacity, in other words a lot of energy is needed to break the attraction so that atoms can move freely, which would increase the water temperature. This property is ...
