Abstract Clarity refers to how deep the light penetrated the water and turbidity is the measure of the light scattering property of water. In this experiment‚ Secchi disk was used to directly measure the amount of penetrated sunlight and indirect amount of the suspended materials in the seawater. The study site was at the littoral zone of the ocean. The coordinates recorded for the study site were found to be N 160 23’ 56.0” E 1190 54’ 06.5” and N 160 24’ 02.5” E 1190 53’ 59.5”.

conditions. They may also be found in deep‚ damp soil litter under the shelter of bushes or trees. So that they were not exposed to a lot of light and there is protection from predators such as blowflies and centipedes‚ sufficient food and damp. The ground was mostly made up of damp organic matter‚ damp soil‚ moist leaves‚ some were found on stony ground. The light intensity is significant to the niche and way of life of the Slater because they are classed as scavengers; they live off decomposing matter

In Darren Aronofsky’s (2010) film‚ Black Swan‚ a ballet dancer experiences significant difficulty in adjusting to fulfill the dual role of the white swan. In order to achieve this role‚ Nina must traverse the dual relationship between the innocence of the white swan and the seductive black swan. In Nina’s desire to reach this goal‚ she experiences a major transformation in herself that reflects the transition from the white and black swan in the ballet. This paper in particular will focus Nina’s

Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the

We can see through the results that there isn’t a normal proportional relationship between the wavelength of the light and the rate of photosynthesis and instead it starts relatively high then decreases and increases again. The colour red gives the highest rate of photosynthesis (89 bubbles per minute) with blue giving the second highest rate of photosynthesis (70 bubbles per minute)‚ and yellow giving the third highest rate of photosynthesis (64 bubbles per minute) and green with by far the least

How light intensity effects the Rate of photo synthesis. Aim The aim of my experiment is to find out how light intensity affects the rate of photosynthesis. Prediction I predict that as the light intensity increases that the rate of photosynthesis will increase in proportion‚ so for example if you increase the light intensity from 10cm away to 20 cm away form a stationary plant. There for the rate of photosynthesis will decrease proportionally with the distance of the light from the plant (in

In conclusion‚ one can determine how photosynthesis is impacted by light intensity through the experimentation on ivy leaf disks in a bicarbonate solution. The function of the sodium bicarbonate in this experiment was to provide a sufficient amount of carbon dioxide (CO2) for the photosynthesis process to occur. Without CO2 or any of the other necessary reactants‚ glucose nor oxygen cannot be produced. The leaves rise and sink due to photosynthesis occurring in the plant cells. As the carbon from

Evidence is the available body of facts or information indicating whether a belief or proposition is true or valid.
