State Standard SB5E. Recognize the role of evolution to biological resistance (pesticide and antibiotic resistance) Biological Resistance (15.2)

Antibiotic Resistance  Bacteria reproduce ____________ and their population grows rapidly.  ____________ can lead to traits that allow certain individuals to be ____________ to antibiotics.  These survivors then reproduce quickly (cloning themselves) and establish a population of antibiotic ____________ bacteria Natural Selection-Speciation-Resistance Chapter 15

Antibiotic Resistance Cont’d 15.3 Natural Selection-Speciation-Resistance Ch. 15

Antibiotic Resistance Cont’d  The ____________ of antibiotics has caused antiobiotic-resistant populations of bacteria to become a ____________ problem.  Methicillin-resistant Staphylococcus aureus (____________) is a bacterium that causes infections in different parts of the body. It's tougher to treat than most strains of staphylococcus aureus -- or staph -- because it's ____________ to some commonly used antibiotics 15.3 Natural Selection-Speciation-Resistance Ch. 15

Antibiotic Resistance Cont’d 15.3 Natural Selection-Speciation-Resistance Ch. 15 Typical appearance of MRSA infection

Pesticide Resistance  Pesticides may kill ____________ members of an insect population, but ____________ allows some individuals to be ____________ to pesticides.  Those who are immune are able to ____________ and ____________, passing their immunity trait to the next generation.  Soon, a whole population of pesticide- resistant insects is thriving Natural Selection-Speciation-Resistance Ch. 15

Pesticide Resistance 15.3 Natural Selection-Speciation-Resistance Ch. 15 ____________ of pesticides has allowed more and more resistant populations to develop.
