  3. Question of the Day Question: What is antibiotic resistance and how does it arise? 4’s Turn In: p. 486 A.Q. 1bc, 2abc

  4. Vocab Sheet

  5. Vocab • Theory (#16)- an explanation that is supported by a large body of evidence; ex: evolution, cell theory • Law (#17)- describes a set of relationships; ex: law of gravity

  6. Vocab • Theory (#16)- an explanation that is supported by a large body of evidence; ex: evolution, cell theory • Law(#17)- describes a set of relationships; ex: law of gravity • Hypothesis (#18)- an educated guess that explains observations; testable More than just a hunch!

  7. Vocab • Lethal (#38)- deadly Lethal allele: causes death

  8. Vocab Sexual Reproduction: • Recombination (#23)- shuffling of genes in new combinations Crossing Over:

  9. Vocab • Evolutionary processes (#22)- • more offspring are born than can survive • individuals have variations • some individuals reproduce more than others

  10. Inv. 9.2: Natural Selection

  11. Notes: Adaptations

  12. Definition • Adaptation- a characteristic that increases an organism’s ability to survive & reproduce • A population adapts to its environment over time • Adaptations arise through natural selection

  13. 3 Types • morphological adaptation- adaptive structure or body part - ex: long tongue of anteater helps in eating ants

  14. 3 Types 2. physiological adaptation- adaptive cells & body systems - ex: platelets help blood clot

  15. 3 Types 3. behavioral adaptation- adaptive reactions to the environment - ex: mating dance of birds

  16. Create an Organism • Pick one item and decide how an organism would use this appendage to help them survive either by (choose one!): • finding food, • hiding from predators, • defending themselves or • finding a mate • In 10 minutes your group will share your organism’s • Name • Typical habitat • How it would use the appendage (arm, leg, mouth, tail…) • What is the purpose of the appendage

  17. Evolution of Eye

  18. Adaptation: The Eye
