  1. 1. Biology Item 06-02 A set-up of bacteria was exposed to radioactive substances. Some offspring were instantly killed and some survived. These survivors were again exposed to radioactive substances, and again the offspring either survived or died. This process was repeated until the dose of radioactive substances was many times as intense as the first dose. This process of producing radioactive resistant bacteria is called: A. budding B. fission C. conjugation D. natural selection www.upcatreview.com
  2. 2. Biology Item 06-02 Natural selection is also described as “ survival of the fittest ”. www.upcatreview.com
  3. 3. Biology Item 06-02 Only the organisms with the proper traits and adaptations can survive under pressures from the environment. www.upcatreview.com
  4. 4. Biology Item 06-02 Other organisms lacking the traits needed for survival are wiped out and cannot produce their next generation (start of extinction ). www.upcatreview.com
  5. 5. Biology Item 06-02 Other organisms lacking the traits needed for survival are wiped out and cannot produce their next generation (start of extinction). www.upcatreview.com
