How do biologists study a problem, what do they use? - Correct Answer The scientific method
What is the definition for each of these levels? Ex. Biosphere, ecosystem, cells, organelles - Correct
Answer Ecology
What are some key features of the principle of evolution? - Correct Answer Overarching theme in
biology, makes sense of everything we know about living organisms
What specific feature are characteristics of all cells? - Correct Answer Enclosed membrane, use DNA as
their genetic information
What is the difference between a eukaryotic cell and a prokaryotic cell? - Correct Answer Eukaryotic
Cell: Has a membrane bound nucleus, usually are part of multiple cell organisms, larger and more
complex, typically have more organelles
Prokaryotic Cell: Lack a membrane bound nucleus, typically part of unicellular organisms, smaller and
less complex.
What types of organisms are included within the prokaryotes? - Correct Answer Prokaryotic: Bacteria
Eukaryotic: Plants and animals
Are your cells prokaryotic or eukaryotic? - Correct Answer Eukaryotic
What is a chromosome? - Correct Answer One long DNA molecule with hundreds or thousands of genes

What is a major difference between chromosomes in eukaryotes and a chromosome in a bacterial cell? -
Correct Answer Bacteria cell: Found in cytoplasm
Eukaryotes: Found in nucleus
How would you define homeostasis? - Correct Answer How organisms maintain internal systems
What is an example of homeostasis? - Correct Answer Humans internal body temperature
How would you define the branch of biology called taxonomy? - Correct Answer The branch of biology
that names and classifies organisms into groups of increasing breadth
Have all the species alive today been classified? - Correct Answer No, approximately 1.8 million species
have been identified and thousands more are identifies each year, but there are 10 to 100 million
species that exist
What are the levels of classification, going from species all the way up to domain? - Correct Answer
Domain, kingdom, phylum, class, order, family, genus, species
What are the 3 domains? - Correct Answer Eukarya, Bacteria, and Archaea
What defines each level of ecology and what types of questions are asked at each level of ecology? -
Correct Answer Organismal ecology: Studying how a specific organism interacts with its surroundings
Population Ecology: How a population interacts with its environment
Community Ecology: How a community interacts with itself and its environment
Ecosystem Ecology: Studying the way biotic and abiotic factors in an ecosystem interact
Landscape Ecology: Improving relationships between ecological processes in the environment and
particular ecosystems
