Communications Technology Essay (1060 words) Communications is defined as the process of sending and receiving information from one person to another. Communications Technology is all the systems we use when we communicate‚ this technology helps us to communicate without the need to be face – to – face with each other. This includes telephone‚ radio‚ television‚ computers and mobile phones. Mobile phones and telephones can be defined as the process when two people are making a conversation over

Unknown Microorganisms May 1‚ 2013 This paper is based on an experiment done in the laboratory over a period of time using the standard method of identifying an unknown microorganism relying on features such as morphology‚ arrangements and biochemical reactions. It was done in succession with each step complimenting the other. At the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The

Aerobic Respiration Breaking down glucose to release energy Products are Carbon dioxide and water Diffusion is … the movement of molecules from a region of high concentration to a low concentration until the concentration is equal. Role of a human circulatory system: Diffuse In – oxygen (O2)‚ dissolved food (glucose) and water (H2O) Diffuse Out – carbon dioxide (CO2)‚waste and water(H2O) Respiration – releasing energy in cells Breathing – getting air into and out of your body

Light reactions are driven by light energy. This pathway produces ATP and a reduced electron carrier (NADPH + H ). The overall reaction is solar energy + 6CO + 6H O -> C H O + 6O + heat. Where photosynthesis takes place in specific groups of organisms‚ cellular respiration is done by all cells. In respiration‚ the energy stored in organic compounds may have been produced by the cell itself or

genetics was an Austrian Monk named Gregor Mendel‚ who established the basic laws of heredity from his studies with pea plants in the late 1800s. Mendel’s fundamental genetic principles may be applied to a variety of traits from many different organisms. Each genetic trait‚ such as flower color‚ is regulated by a pair of genes called alleles. These alleles are found at particular places on the chromosomes called loci. During meiosis‚ each pair of alleles splits up or segregates so that only one
