follows; 6H₂O + 6CO₂ C₆H₁₂O₆ + 6O₂1 There are four variables that affect the rate of photosynthesis; light intensity‚ temperature‚ CO₂ and water.2 However‚ is it possible to count in the colour of light‚ too‚ which I am going to investigate in this lab. Since the photosynthesis takes place in chloroplasts that has chlorophyll‚ the rate of photosynthesis can be affected by different colours of light‚ since the absorption of light changes within different colours. Research Question: What colour of

Background Research Yeast are eukaryotic microorganisms just like other organisms‚ they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine triphosphate (ATP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can be summarized by the equation: . Enzymes play a very significant part in respiration. During the different stages of respiration‚ enzymes

Biology 102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen

pH indicators‚ in chemistry‚ are usually a weak acid or base that are naturally occurring in various plants and flowers and can act as dyes. Some examples of indicators are Litmus (Comes from a plant species called a lichen)‚ Phenolphthalein‚ Thymol blue‚ Bromocresol green and Universal indicator. All these indicators have a certain turning point in color once a certain concentration equilibrium of Hydrogen cations in reached (H +) or a certain concentration equilibrium of H3O+(Also OH - using Arrhenius
