  1. The Science of Life I. Organization of Life A. Domains of Life B. Viruses C. DNA D. Evolution

  2. A. Domains of Life nucleus Prokaryotes and eukaryotes Three Domains Prokaryotes 1. Archaea 2. Bacteria Eukaryotes 3. Eukarya • Protista • Plants • Fungi • Animals Bonobos

  3. A. Domains of Life 1. Archaea (-um) Prokaryotes Extremophiles autotrophs

  4. 2. Bacteria (-um) Escherichia coli (E.coli) Staphylococcus aureus • pathogen Resistance and Natural Selection

  5. 2. Bacteria (-um) Cell reproduction Inside bacteria cells ubiquitous loopy (cell membrane) autotrophs heterotrophs

  6. In which of the following environments would you most likely find an archaeum? a. on the leaf of a tree b. on a table top c. inside of a volcano d. in a dog’s mouth

  7. 3. Eukarya Fungi Animalia Protista Plantae

  8. Malaria Chagas Sleeping sickness a. Protista Intracellular parasites Single celled; nucleus Autotrophs and heterotrophs

  9. b. Fungi Cell wall Spores Extracellular digestion Filamentous growth Hypha(e)

  10. Human Pathogens Candida albicans • Yeast infection • Cradle cap • Thrush Pneumonia Penicillium Athlete’s foot Ringworm Heterotrophs

  11. c. Plants Light Energy PS: 6CO2 + 6H2O C6H12O6 + 6O2 Autotrophs

  12. Invertebrates Vertebrates d. Animals No cell walls Heterotrophs

  13. Which of the following contains no autotrophs? a. fungi b. plants c. protista d. bacteria e. more than one of these Which is a difference between prokaryotes and eukaryotes? a. prokaryotes don’t have DNA; eukaryotes do b. prokaryotes don’t grow or reproduce; eukaryotes do c. prokaryotes have a nucleus; eukaryotes don’t d. eukaryotes have a nucleus; prokaryotes don’t

  14. What can autotrophs do that heterotrophs cannot do? a. maintain homeostasis b. move from one place to another without any aid c. produce carbon dioxide d. make their own carbohydrates

  15. Cold Ebola HIV Flu B. Viruses ERVs H1N1

  16. B. Viruses: Infection protein coat viral DNA or RNA Infect more cells Living or non-living?

  17. Which of the following is a reason for why viruses are considered non-living? a. they can’t be killed b. they don’t have a nucleus c. they don’t have DNA d. they don’t metabolize Of the following, which is the best treatment for a viral infection? a. antibiotics b. get rest and drink liquids c. run a marathon d. eat lots of chocolate and watch Oprah

  18. C. DNA: Unity and Diversity of Life Double helix

  19. Genetic code C. DNA: Unity and Diversity of Life Two roles of DNA: • Self replication • Genetic code A, C, T, G

  20. DNA is like a cookbook • Genes are likerecipes for proteins • Codons are like the words in the recipes • Amino Acids are like the ingredients • RNA is like the cook • ATCG are likethe letters of the words DNA Analogy • Ribosomes are like the ovens

  21. In the DNA analogy, what are codons? a. the recipes b. the cooks c. the letters d. the words

  22. D. Evolution:the Organizing Principle of Biology Evolution explains why organisms are similar (common ancestry) and why they are different (adaptation). Natural selection- the main theory of evolution Theory- a well documented, explanatory principle Antibiotic resistance

  23. D. Evolution:the Organizing Principle of Biology • Genetic variation is the raw material for evolution Natural selection

  24. More myths of evolution Misconceptions About Evolution 1. Many scientists reject evolution. 2. There are no transitional forms (missing links) in the fossil record. 3. Evolution is just a theory. Theory – a well-documented, explanatory principle 4. If humans evolved from monkeys, why are there still monkeys around? 5. Only atheists believe in evolution.

  25. What is the raw material for evolution? a. natural selection b. reproduction c. genetic variation d. environmental change A theory is a well documented, _____ principle. a. expository b. explanatory c. entertaining d. expeditious

  26. Cell Biology in the News

  27. What is the controversy over PGD? a. it can be used to detect lethal genetic disorders b. it can be used to detect non-lethal genetic disorders c. it can be used to detect the sex of an embryo d. more than one of these is controversial

  28. The Founding Fathers of Biology Aristotle (384 – 322 BCE)

  29. The Founding Fathers of Biology Charles Darwin (1809-1882) Gregor Mendel (1823-1884)

  30. Concept map

  31. The End

  32. Scientific Support for Evolution NABT The rest of the world? NAS AAAS

  33. The Clergy Letter Project
