Biology Exam Questions and Answers
Define the concept of emergent properties and describe an example. - Answer-New
properties that arise in the hierarchy of life due to interactions among parts
Explain why cells are a special level in biological organization. - Answer-They are the
level that life emerges
Compare prokaryotic and eukaryotic cells. - Answer-Prokaryotic- First to evolve, are
simple, smaller
Eukaryotic- Found in plants, animals, fungi., are subdivided into various organelles
Compare the dynamics of nutrients and energy in an ecosystem. Which one flows
through the ecosystem? Which one cycles? Why is the sun important? - Answer-
Recycling of chemical nutrients from the ecosystem through producers, consumers, and
decomposers back into the ecosystem
Oneway flow of energy though an ecosystem
Recycling-Cycles
Oneway flow-flows
The sun is the inflow of energy in both
What is DNA? What is so important about this molecule? - Answer-The chemical
substance of genes.
All cells have it.
Compare the three domains of life. - Answer-Bacteria are the most diverse prokaryotes.
Archaea live in Earth's extreme environment's; also prokaryotes.
Eukarys include single cell protists, multicellular fungi, animals, and plants.
Describe the process of natural selection. Do individuals or populations evolve? -
Answer-Populations with varied traits, elimination of certain traits. Increasing of certain
traits. Populations evolve.
Distinguish between quantitative and qualitative data. - Answer-Qualitive data is
descriptive.
Quantitive includes numerical measurements.
Compare the definitions and use of inductive and deductive reasoning in scientific
investigations. - Answer-Inductive makes generalizations based on large numbers of
specific observations.
Deductive flows from general premise to predicted and specific results.
Distinguish between a scientific theory and a hypothesis. - Answer-Theory: is much
broader and is supported by large and growing body of evidence.
