Biology 1003 - Cells: Size‚ Structure and Microscopy Introduction What is life? What are the key factors that biologists have defined that apply to every single organism on the planet? In the 17th century‚ due to the amazing advancement of the microscope‚ biologists created a theory to differentiate the living from the non-living called the cell theory. One concept from the theory is that all living organisms are composed of one or more cells. The importance of studying cells is akin to the importance

metaphase‚ anaphase and telophase. Interphase The DNA duplicates during interphase to prepare for mitosis. Chromosomes are not clearly discerned in the nucleus. Prophase Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nuclear membrane dissolves. Microtubules attach at the kinetochores and the chromosomes begin moving. Metaphase Spindle fibers align the chromosomes along the middle of the cell nucleus. This line is referred to as the metaphase

1)medicine of the renaissance epoch : The Renaissance was a great period of intellectual growth and artistic development in Europe. . As part of that scientists and thinkers began to shake loose from the traditional views that governed medicine in both the east and the west. The focus of treatments was no longer a divinely ordained natural balance. Knowledge advanced through the scientific method—conducting experiments‚ collecting observations‚ reaching conclusions.
