Biology 100 - Exam 1
with correct answers
What is Biology?CORRECT-ANSWERSThe study of all living things.
What are the properties of life?CORRECT-ANSWERS1. Cellular Organization
2. Metabolism
3. Homeostasis
4. Growth and Reproduction
5. Heredity
What is cellular organization and or Cell Theory?CORRECT-ANSWERSAll living things are comprised of at
least one cell.
,What is Metabolism?CORRECT-ANSWERSAll living things process energy which is used to power other
life process such as growth and reproduction.
What is Homeostasis?CORRECT-ANSWERSAll living things maintain a stable environment which
optimizes conditions for life processes.
All organisms have the capacity for?CORRECT-ANSWERSReproduction
What do all organisms pass from parents to offspring?CORRECT-ANSWERSGenetic Information
What are the 5 Biological Themes?CORRECT-ANSWERS1. Evolution
2. The Flow of Energy
3. Cooperation
4. Structure Determines Function
5. Homeostasis
What is evolution?CORRECT-ANSWERSAdapting to environment over time by making genetic changes
within a species.
What is the primary mechanism for evolution?CORRECT-ANSWERSNatural Selection
What is Natural Selection?CORRECT-ANSWERSIndividuals with characteristics that improve their
survival, reproduce and pass characteristics to offspring.
What is Artificial Selection?CORRECT-ANSWERSIndividuals are selected for reproduction based on
desirable traits.
How does energy flow through the living world?CORRECT-ANSWERSSUN -- PHOTOSYNTHESIS --
HERBIVORY --PREDATION -- DECOMPOSITION
In what ways do organisms acquire energy?CORRECT-ANSWERSAutotrophy
, Heterotrophy
What does autotrophy mean?CORRECT-ANSWERSThe organism produces their own energy through
photosynthesis.
What does Heterotrophy mean?CORRECT-ANSWERSThe organism gets energy from other organisms.
What are the steps in the Scientific Method?CORRECT-ANSWERS1. Observation
2. Hypothesis
3. Predictions
4. Test
5. Control Variables
6. Evaluate and Conclude
What are the 6 Kingdoms of Life?CORRECT-ANSWERS1. Archaea - Kingdom of prokaryotes (do not have
nuclei)
2. Bacteria - Second Prokaryote Kingdom
3. Protista - Most unicellular eukaryotes (have a nucleus) along with multicellular algae.
4. Fungi - Contains nonphotosynthetic organisms that digest their food externally.
5. Plantae - Contains photosynthetic multicellular organisms, such as flowering plants.
6. Animalia - Nonphotosynthetic multicellular organisms that digest their food internally.
What are the four main theories?CORRECT-ANSWERS1. Cell Theory
2. Gene Theory
3. Theory of Heredity
4. Theory of Evolution
Who developed the cell theory?CORRECT-ANSWERSRobert Hooke in England in 1665 while looking at
cork.
