Hello, I purchased a Dell Inspiron N5110 last year and added on Microsoft Office at purchase. It came pre-installed on the lap top. A few weeks back I got a nasty virus that messed up my lap top and I've decided to reset it to factory settings instead of trying to mess with it.The only thing important on my lap top is my MS office, the rest is already on my desktop.o, before you re-install Windows, do a full image copy backup of your current situation. That way you will be able to recover any missing files. Make sure you can extract individual files from the backup.
Louis Pasteur Actually,  Louis Pasteur (1822-1895) is credited with DISPROVING spontaneous generation, expanding the work of other scientists before him. Aristotle synthesized the theory of spontaneous generation, compiling and expanding on the work of earlier natural philosophers.
Matthias Schleiden helped to reject the theory of spontaneous generation by providing evidence of plants and how their organisms grew. Theodor Schwann Theodor Schwann discovered that plants are made up of cells using a microscope, which also supports the cell theory.ike Newton, the cell theory would not have been developed without the invention of the microscope. In order for Matthias Schleiden, Theodor Schwann, and Rudolf Virchow to create the cell theory, they needed the microscopes that Hans and Zacharias Jansen had invented prior to their discoveries.
