in size and easier to study than human chromosomes. Discussion I observed that polytene chromosomes had formed just like my prediction. This result supports my hypothesis that endomitosis has occurred. I observed that polytene chromosomes were big‚ light and had dark banding patterns with all homologous pairs of chromosomes connected to chromocentre similar to Baudisch ’s observation in his 1977 paper. The disadvantage of the method used was that the extraction process was very hard and without lots

ADI Lab investigation: Photosynthesis Introduction and goals: In our experiment we worked with photosynthesis‚ which is the process of light energy‚ CO2 and H2O being turned into food for the plant. CO2+H2O+ Light energy=C6H12O+O2 is the formula for photosynthesis. Our group hypothesis was trying to determine weather o2‚ water‚ or the nutrients of the soil determine the mass of the water. The guided question was “Where does the mass that makes up a plant come from?” Methods:

Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

lesson‚ you need to know a little bit about light. White light consists of all the colors of the rainbow mixed together. Diffraction refers to various phenomena which occur when a wave encounters an obstacle. In classical physics‚ the diffraction phenomenon is described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings. Isaac Newton thought that light must be a particle because particles of light that travels in straight lines until they are

Lights‚ Camera‚ Action. Light it up. As the popular Soca song goes‚ ‘Let me see you light up the Air’. Or Vybz Kartel’s song says ‘Light the Weed’. All focused around the presence of light. We cannot see without light‚ so in this regard‚ light illuminates our path. For this reason we ensure that our surroundings are fitted with lightbulbs. We cannot function in school or work or in life if there isn’t some measure of light. I’m here to enlighten you about the choice that you will face when purchasing
