Define biology.
List and explain the characteristics of life.
Explain what is meant by the theme that life is organized.
Define and differentiate between reductionism, emergent properties, and systems biology.
Explain how structure and function are correlated with each other.
List the levels of organization of life, explain each, and give examples of each.
Explain what is meant by the theme that life requires and uses information.
Describe how living things store and use information to maintain life (Theme #2)
Define and explain what a chromosome is.
Define and explain what a gene is.
Describe the structure of DNA.
Explain what is meant by fact that the two strands of a DNA molecule are complementary to each other. Define gene expression and explain what must occur for a gene to be expressed.
Explain, in brief, what occurs during transcription.
Explain, in brief, what occurs during translation.
Explain what the genetic code is. (**You do not necessarily need to understand how to use it for this chapter) Define the word genome and explain what it is.
Define genomics and give an example.
Define proteomics and give an example.
Define bioinformatics and give an example.
Explain why life requires energy (Theme #3).
Define and compare and contrast producers and consumers.
Explain why energy flows in a one-way direction, but chemicals (matter) is continually recycled.
Explain why and how life requires interactions (Theme #4).
Give examples of how life interactions occur between organisms, between organisms and the environment, and within organisms.
Explain the similarities and differences between negative and positive feedback and recognize each in a given scenario.
Explain what is meant that life evolves (Theme #5).
Define taxa and give an example of one.
Define taxonomy and explain why it is necessary.
List the five domains and give an example of an organism that would be found in each.
Describe the characteristics of each of the five domains.
List the three kingdoms of the domain Eukarya and give an example of an organism that would be found in each.
Describe the characteristics of each of the three kingdoms of the domain Eukarya.
