  1. KEY CONCEPTTechnology continually changes the way biologists work.

  2. stoma Imaging technologies provide new views of life. • A microscope provides an enlarged image of an object. • light microscopes (LM)

  3. stoma Imaging technologies provide new views of life. • A microscope provides an enlarged image of an object. • light microscopes (LM) • scanning electron microscopes (SEM)

  4. stoma Imaging technologies provide new views of life. • A microscope provides an enlarged image of an object. • transmission electron microscopes (TEM) • light microscopes (LM) • scanning electron microscopes (SEM)

  5. Imaging technology is used in medicine. • X-ray images

  6. Imaging technology is used in medicine. • magnetic resonance imaging (MRI) • X-ray images

  7. Imaging technology is used in medicine. • functional MRI (fMRI) • X-ray images • magnetic resonance imaging (MRI)

  8. Complex systems are modeled on computers. Normal heartbeat • Computer models are used to study systems that cannot be studied directly. • heart attacks • effect of medicines on the human body • movement of water molecules into and out of a cell • spread of a disease through a population Heart attack • Computer models are used when experiments are not safe, ethical, or practical.

  9. The tools of molecular genetics give rise to new biological studies. • A gene is a segment of DNA that stores genetic information.

  10. Through our understanding of DNA, we can study genetics on a molecular level. • molecular genetics • genomics
