are widely distributed among organism today.
*Discuss the various methods of genetic diversity in prokaryotes.
 Mutation
 Genetic Recombination
-transformation
-transduction
-conjugation
*Describe key adaptations that contribute to prokaryote success.
 cell wall

*Explain how prokaryotes use specialized membranes to carry out basic metabolic tasks.
*Distinguish between the four major modes of prokaryote nutrition.
 Obligate aerobes
 Obligate anaerobes
 Anaerobic respiration
 Facultative anaerobes
*Describe the crucial role of prokaryotes in the biosphere.
 Nitrogen fixation
 Decomposers
 Mutualistic relationships
*Explain quorum sensing and explain why it is important to bacteria from the aspect of natural selection.
LO 1.17 The student is able to pose scientific questions about a group of organisms whose relatedness is described by a
phylogenetic tree or cladogram in order to (1) identify shared characteristics, (2) make inferences about the
evolutionary history of the group, & (3) identify character data that extend or improve the phylogenetic tree.[See SP 3.1]
LO 1.18 The student is able to evaluate evidence provided by a data set in conjunction with a phylogenetic tree or a
simple cladogram to determine evolutionary history and speciation. [See SP 5.3]
LO 1.19 The student is able create a phylogenetic tree or simple cladogram that correctly represents evolutionary history
and speciation from a provided data set.[See SP 1.1]
* Construct a cladogram or phylogenic tree that represents each of the following evolutionary relationships.
Under each diagram define each derived characteristic and explain the advantage of each. (3)



number of heart chambers in animals (2 chambered, 3 chambered, 4 chambered)
plant diversity (moss, ferns, gymnosperms, angiosperms)
-spores/seeds
-vascular/nonvascular
-cones/fruit
digestive mechanisms in animals (collar cells, gastrovascular cavity, alimentary canal, digestive system)
LO 1.26 The student is able to evaluate given data sets that illustrate evolution as an ongoing process. [See SP 5.3]
*Describe an example of evolution? (2)
 Eukaryote limbs
 Eukaryote nervous system
 Prokaryotes to Eukaryotes (endosymbiotic theory)
LO 2.25 The student can construct explanations based on scientific evidence that homeostatic mechanisms reflect
continuity due to common ancestry and/or divergence due to adaptation in different environments. [See SP 6.2]
LO 2.26 The student is able to analyze data to identify phylogenetic patterns or relationships, showing homeostatic
mechanisms reflect both continuity due to common ancestry & change due to evolution in different environments.SP 5.1
LO 2.27 Student is able to connect differences in the environment with the evolution of homeostatic mechanisms. SP 7.1
*Compare the various mechanisms organisms use for obtaining nutrients and eliminating wastes and relate it to
evolutionary adaptations? (3)
 digestive mechanisms in animals such as food vacuoles, gastrovascular cavities, one-way digestive system
-include representative organisms
-Surface area
 respiratory systems of aquatic versus terrestrial organisms (water  to land include representative organisms)
-moist membranes
-Gills
-Lungs/alveoli
-Skin
-Tracheal system
-Countercurrent exchange
 nitrogenous waste production and elimination in aquatic (fish) and terrestrial animals (birds and mammals)
-include representative organisms
-ammonia
-Urea
-Uric Acid
*Discuss how homeostatic control systems in species support common ancestry?
 excretory systems in flatworms, earthworms and vertebrates
-protonephridia, metanephridium, nephron
 osmoregulation in bacteria, fish and protists
-diffusion/osmosis, osmoconformer, osmoregulator, contractile vacuole
 circulatory system in fish, amphibians, and mammals

*Discuss how Archaea Bacteria have adapted to different extreme environments?
 Thermophiles, Halophiles and Methanogens
LO 2.31 The student can connect concepts in and across domains to show that timing and coordination of specific events
are necessary for normal development in an organism & these events are regulated by multiple mechanisms.(See SP 7.2]
LO 2.32 The student is able to use a graph or diagram to analyze situations or solve problems (quantitatively or
qualitatively) that involve timing and coordination of events necessary for normal development in an organism. [ SP 1.4]
