Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide‚ affected the rate of photosynthesis. The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). A valid conclusion was made and most of the results were in accordance with the prediction‚ although there were some anomalies present. The errors and limitations were evaluated and some improvements were suggested. Introduction: Photosynthesis

Solar power From Wikipedia‚ the free encyclopedia This article is about generation of electricity using solar energy. For other uses of solar energy‚ see Solar energy. The PS10 concentrates sunlight received from a field of heliostats onto a central tower. Solar power is the conversion of sunlight into electricity‚ either directly using photovoltaics (PV)‚ or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus

New ’solar paint’ could generate electricity from the roofs and walls of EVERY home without the need for bulky panels * ’Nanocrystals’ used to generate power * Can be painted or printed onto walls or windows * So tiny you could fit 250‚000‚000‚000 on head of a pin * Thin enough to be painted or printed onto walls One day‚ a thin film of ’solar panel’ could be painted over windows and walls to turn every home into a giant hi-tech ’sun trap’. The hi-tech solution could make solar

Planets and moons in our solar system share many similar properties‚ but there are also many ways they are different. Some of the main differences come with the different geologic activity‚ composition‚ interior structure‚ magnetic field‚ and atmosphere that distinguish some planets and moons from others. The first way to separate the planets as far as their surfaces is breaking them into their two categories. The Jovian planets (Jupiter‚ Saturn‚ Uranus‚ Neptune) are primarily composed of gas and

The difference between bacteria‚ viruses‚ fungi and parasites are: Bacteria are single celled organisms that can rapidly multiple themselves every 10 minutes up to 10 times each bacterial cell‚ but they do not live or reproduce in a human cell. When threatened they will make a copy of their DNA to enable them to come back to life in the right conditions. They are able to survive in most extreme living conditions including with and without oxygen‚ there are various types of bacteria such as Cocci/Coccus

The researchers were able to gather information from different journals and newspapers that already featured the solar panel. Moreover‚ they indicate information that was gathered from the internet. This study used descriptive method of research because the researchers aim to elaborate all the features of solar panel. The study was designed to give knowledge on the use of solar panel

A life starts as a cluster of undifferentiated embryonic stem cells‚ which later give rise to different cells of our particular organs. To truly comprehend and appreciate the complexity of human bodies‚ we need to investigate the development of stem cells in subcellular level. Stem cells have the capacity of self-renewal

In photosynthesis‚ light energy is transformed into chemical energy‚ thus chemical energy is the product. This is different from respiration because respiration transforms chemical energy into energy usable by cells; in this case chemical energy is the source. Photosynthesis occurs in the chloroplasts‚ using the chlorophyll inside of the chloroplasts‚ while respiration occurs in the mitochondria. Photosynthesis produces oxygen as a by-product‚ while aerobic respiration requires oxygen to even work

Contents Introduction Solar energy has experienced an impressive technological shift. While early solar technologies consisted of small-scale photovoltaic (PV) cells‚ recent technologies are represented by solar concentrated power (CSP) and also by large-scale PV systems that feed into electricity grids. The costs of solar energy technologies have dropped substantially over the last 30 years. The rapid expansion of the solar energy market can be attributed to a number of supportive

SOLAR ENERGY INTRODUCTION SOLAR ENERGY is the radiant energy that we receive from the sun in the form of heat and light. It is an inexhaustible source of energy. Solar Energy is the ultimate source of most of the sources of energy that we use. The wind energy‚ water energy‚ energy of fossil fuels and the energy in food are due to solar energy. SOURCE OF SOLAR ENERGY The discovery of radioactivity led some scientists to suggest that the energy released during radioactive decay of radioactive
