The solar energy use in Africa These days‚ solar energy has been the most talkative alternative energy source in the world. Unlike the gas‚ oil‚ and coal‚ solar enrgy is one of the clean and renewable resource‚ which can not only generate power but also protect the environment. Africa‚ has second largest population‚ estimated 1.6 billion‚ however‚ around one third of it’s people still live in the condition with no eletricity. (Renewable energy in Africa

1. Is there is a common reason for the absences? Explain. Absences only occurred for band class at Truman and Jackson Middle Schools. Absences must have been due to something occurring in both Truman and Jackson band courses on May 20th and 21st. (and only May 22nd for Truman) All other attendance is normal in all other classes and Middle Schools and are not suspicious. ---see evidence and analysis of evidence for more information-- 2. Come up with two testable‚ clear hypotheses about what

Smithsonian Laboratory Early Atmosphere 1. How abundant was oxygen in the early atmosphere? The earth’s early atmosphere contained only small amounts of free oxygen‚ produced by the reaction of water vapor with sunlight. The oxygen rich atmosphere that developed later and on which oxygen breathing life now depends was result of the origin and spread of organisms capable of photosynthesis. 2. What evidence do scientists have that the oxygen content of our atmosphere has increased since the earth’s

physics‚ energy is an indirectly observed quantity which comes in many forms‚ such as kinetic energy‚ potential energy‚ radiant energy‚ and many others; which are listed in this summary article. This is a major topic in science and technology and this article gives an overview of its major aspects‚ and provides links to the many specific articles about energy in its different forms and contexts. The question "what is energy?" is difficult to answer in a simple‚ intuitive way‚ although energy can be

The importance of carbohydrates in living organisms Carbohydrates contain carbon‚ hydrogen and oxygen in the ratio of 1.2.1.. There are many different types of carbohydrate‚ all of which are useful to living organisms. The most important carbohydrate is probable glucose. Glucose is a monosaccharide and is the monomer unit which makes up more complex polysaccharides. Two glucose molecules can be joined in a condensation reaction‚ whereby water is removed‚ for example to produce maltose‚ a disaccharide

Genetics X143 Professor Yund 4.23.13 How do genes generate the Phenotype? “Every aspet of an organism is determined or influenced by the genes of the organism” What genes are‚ what they do‚ how they interact with eachother and the enviroment to generate a phenotype. Genes are segments of DNA that code for proteins or RNA molecules. These genes are the genetic material that is passed down from generation to generation in all species. The individual DNA segments each individual carries are

Human Is A Complex Organism Human beings are complex and special organisms as there is a complex organisation of cells in the human body. The organisation in the human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism.The same type of cells which carry out a specific function are organised into a tissue. For example‚ a group of nerve cells form a nerve tissue. They are organised to work together to perform specific functions as the result of cells in the human body do

Arterial Blood Gas Values: 1. Respiratory acidosis 2. Metabolic alkalosis 3. Normal 4. Respiratory alkalosis Case Study: 1. When listening to the patient I would expect to hear crackles and wheezing. 2. Normal oxygen saturation is 95% to 100%. 3.Since the patient does have a history of diabetes and asthma‚ he has a higher risk of contracting viruses due to the fact that diabetes lowers your immune response‚ and asthma causes your airway to become more sensitive.

[Energy resources]: The 2 broad types Pros and Cons of each type Ways in which they are harnessed There two main types of energy these are: 1. Potential energy 2. Kinetic energy Potential energy Potential energy is energy stored due to position. The following are some example in which potential energy can be found. 1. Wound-up spring When a spring of a dock work toy car unwinds‚ the stored energy in the spring drives the wheels and the car moves. The wound-up spring is said to posse potential

Research how humans interact with micro-organisms and use this information to write a discussion for your report. Basic structure and function Explain the parts and how they work for fungi and bacteria Most fungal species are multicellular. Most fungi do not have flagella in any phase of their life cycle. They move toward food by growing toward it. The main body of most fungi is made up of fine‚ branching‚ and usually colourless threads called hyphae. Each fungus will have vast numbers
