partially separated from the environment outside the cell‚ it exists within all living organisms as its basic structure. The study of cells is made possible through the use of cytology’ the preparation of materials for examination through microscopes as an average animal cell exists on a scale of 10 microns roughly one hundredths of a millimetres. Originally light microscopy was used in this field but with the advancement of knowledge scientists were restricted to 200nm magnification‚ or 2

You expose the bacteria Staphylococcus aureus to low levels of antibiotic methicillin. The surviving bacteria are then exposed to higher concentrations of methicillin and the process repeated until a strain of methicillin-resistant S. aureus (MRSA) was generated. To test your hypothesis‚ you perform an experiment

1. INTRODUCTION A solar cell is a device that converts the energy of sunlight directly into electricity by the photovoltaic effect. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight‚ while the term photovoltaic cell is used when the light source is unspecified.”Photovoltaics” the field of technology and research related to the application of solar cells in producing electricity for practical use.

Robert Hooke first described cells in 1665 while observing cork with a microscope he built himself. * Then Anotnir van Leeuwenhoek observed the first living cells and referred to them as ‘animalcules.’ Meaning little animals * 1838‚ Mathias Schleiden states that plants are made
