BSC1005 MIDTERM MDC EXAM Q’S AND A’S
What is Biology? - -The scientific study of life.
-Proper components of the SCIENTIFIC METHOD. - -Observation, Question, Hypothesis,
Prediction, Experiment, Results, Conclusion.
-Taxonomy is the ____? - -Naming and classifying of species.
-Which Kingdom of Eukarya consist primarily of unicellular organisms? - -Protista
-What accounts for the different breeds of domesticated dogs? - -Artificial selection.
-Relative to prokaryotic cells, eukaryotic cells are usually ______. - -EUKARYOTIC: Larger,
and MORE COMPLEX.
-What does adaption mean in a biological context? - -The accumulation of favorable
variations in a population over time.
-What is the difference between discovery science and hypothesis driven science? - -
Discover science describes natural structures and processes as accurately as possible
through careful observation and data analysis.
Hypothesis- driven science is the observation and induction of discovery science. It
stimulates us to seek natural structures and processes.
