Biology Study Guide Unit 10, 11, & 12 (ANSWERS)
Unit 10 - Classification
1. Memorize this table on characteristics of living organisms in the kingdoms Eubacteria, Archeabacteria, Protista, Fungi,
Plantae, and Animalia.
2. Seven levels for classification in the correct order from largest to smallest (KPCOFGS)
Kingdom, Phylum, Class, Order, Family, Genus, Species
3. What are the 3 domains and know which kingdoms are under each one?
Domain Bacteria Domain Archaea Domain Eukarya
Eubacteria Archaebacteria Protista
Fungi
Plantae
Animalia
4. What is binomial nomenclature? What is the genus and which is the species?
- A two-word naming system in which the first name (genus name) is capitalized and the second name (species
name) is lowercased.
5. What is a cladogram used for?
- illustrates how groups of organisms are related to one another by showing how evolutionary lines, or lineages,
branched off from common ancestors
6. Given a figure, be able to read a cladogram to understand ancestry
7. What is embryology?
-Is the study of how early developmental stages of many animals with backbones (vertebrates) look very
similar.
8. What makes fungi different from the rest of the kingdoms in the domain Eukarya?
-One type of fungi is a mushroom; fungi are heterotrophs that cannot make food by photosynthesis
9. Which kingdom in the domain Eukarya did the other kingdoms evolve from?
- The one that came first / Protista
Unit 11 – Mechanisms of Evolution/Mutations
10. What is evolution? Who came up with the theory of evolution?
- Evolution is the process of change over time / Charles Darwin came up with the theory of evolution and wrote
about it in his book Origin of Species
11. What other scientists contributed to the theory of evolution?
- Darwin, Malthus, Lamarck, Lyell, Wallace
12. Why was Miller-Urey experiment so sufficient?

Unit 10 - Classification

1. Memorize this table on characteristics of living organisms in the kingdoms Eubacteria, Archeabacteria, Protista, Fungi,

Plantae, and Animalia.

2. Seven levels for classification in the correct order from largest to smallest (KPCOFGS) Kingdom, Phylum, Class, Order, Family, Genus, Species 3. What are the 3 domains and know which kingdoms are under each one? Domain Bacteria Domain Archaea Domain Eukarya Eubacteria Archaebacteria Protista Fungi Plantae Animalia 4. What is binomial nomenclature? What is the genus and which is the species? - A two-word naming system in which the first name (genus name) is capitalized and the second name (species name) is lowercased. 5. What is a cladogram used for? - illustrates how groups of organisms are related to one another by showing how evolutionary lines, or lineages, branched off from common ancestors **6. Given a figure, be able to read a cladogram to understand ancestry

  1. What is embryology?** - Is the study of how early developmental stages of many animals with backbones (vertebrates) look very similar. 8. What makes fungi different from the rest of the kingdoms in the domain Eukarya? - One type of fungi is a mushroom; fungi are heterotrophs that cannot make food by photosynthesis 9. Which kingdom in the domain Eukarya did the other kingdoms evolve from?
    • The one that came first / Protista

Unit 11 – Mechanisms of Evolution/Mutations

10. What is evolution? Who came up with the theory of evolution? - Evolution is the process of change over time / Charles Darwin came up with the theory of evolution and wrote about it in his book Origin of Species 11. What other scientists contributed to the theory of evolution? - Darwin, Malthus, Lamarck, Lyell, Wallace 12. Why was Miller-Urey experiment so sufficient?

  • 1 st^ experiment that recreated the atmosphere of early Earth and that same experiment has been recreated by modern scientists to show similar results. 13. Describe the scientific explanations of the origin of life on Earth.
  • Evolved from little or no oxygen to having oxygen due to the synthesis of organic molecules
  • Evolved from prokaryotic cells to eukaryotic cells 14. What are the 3 conditions or requirements for natural selection to occur? Describe each condition.
  1. Struggle for existence – more individuals are born than can survive
  2. Variation and adaptation – there are natural heritable variation
  3. Survival of the fittest - there are variable fitness among individuals meaning that the organism with higher fitness survives 15. What is the difference between genetic drift and gene flow?
  • Genetic drift: occurs when random or chance events determine which alleles are passed to the next generation / significant ONLY for small populations
  • Gene flow: occurs when alleles are transferred from one population to another via movement of individuals (migration) or gametes (plant pollen dispersal) 16. How do mutations and genetic recombination increase genetic variation?
  • It increases the organisms’ likeliness to survive. Natural selection promotes genetic diversity or variation. 17. Be able to interpret an evolutionary tree when given a picture of one.
  • The tree shows that organisms share common ancestry. 18. What are the 6 areas that are studied to find evidence of evolution? Explain each one and provide an example of each.
  1. Biogeography: the study of where organisms live (now and in the past)
  2. Fossil record: recently discovered fossils form series that trace the evolution of modern species from extinct ancestors
  3. Comparative anatomy: (a.) homologous structures: structures that are similar in different species of common ancestry / (b.) analogous structures: body parts that have a common function but not structure / (c.) vestigial structures: structures that are inherited from ancestors but has lost much or all of its original function
  4. Comparative embryology: the study of how early developmental stages of many animals with backbones (vertebrates) look very similar
  5. Genetics: the genetic code (DNA) is nearly identical for all organisms
  6. Natural Selection: the process where organisms with variations best suited to their environment survive 19. What is the endosymbiotic theory?
  • Theory that proposes that eukaryotic cells formed from a symbiotic relationship among several different prokaryotic cells 20. What is the purpose of studying those 6 areas that support the theory of evolution?
  • To see how organisms are related to one another and to see possible common ancestry.

Unit 12 – Hominid Evolution

21. Explain the basic trends in hominid evolution from early ancestors 6 million years ago to modern humans, including

6 million years ago Present time

Brain size 900 cc 1400 cc / increased

Jaw size Narrow, larger jaw / larger teeth Wider, smaller jaw / smaller teeth

Language Smaller brain / less language Larger brain / more language

Manufacture of tools Basic tools / less gripping ability Complex tools / more gripping ability
