[Bio2] Guide Questions for the Long Test

Cs, Li, Mg!, Na – Long Test will take place as scheduled but coverage is cut short. You may review using the guide questions given below. If you opt to answer this in your notebooks, recitation credit of 0.5 pts per correct answer will be given.
Guide Questions for the Bio 2 Loooooong Test (from Levels of Bio Organization to Cellular Transport)
Levels of Biological Organization
• List the different levels of biological organization from simple to complex.
• Define emergent property and give an example.
Multicellularity and the Volvocine Series
• What are some adaptations to get around the problem posed by SA:V?
• Describe the colonial theory using the volvocine series as a model to explain the evolution of multicellularity.
• Discuss the advantages and problems of multicellularity.
Plant and Animal Tissues
• Describe the structures of the different plant and animal tissues and relate these to their functions.
Bioenergetics and Digestion
• Define: metabolism, anabolism, and catabolism.
• What is the relationship between size and relative metabolic rate (per unit mass).
• Enumerate the four processes that must be accomplished during digestion.
• Describe the following digestive processes in organisms with: a) intracellular digestion only, b) extracellular digestion only, c) incomplete digestive systems, and d) complete digestive system. Name the types of animals associated with the given type of system.
