BIO 100 FIRST EXAM QUESTIONS AND
CORRECT ANSWERS
The systematic way scientists study the natural world using observation, experimentation,
and reasoning. - Nature of Science
A structured approach to answering questions that includes observation, question,
hypothesis, experiment, data collection & analysis, conclusion, and communication of
results. - Scientific Method
A testable explanation based on observations. - Hypothesis
A well-substantiated explanation that incorporates facts, laws, and tested hypotheses
(e.g., Cell Theory, Evolution). - Theory
A statement describing consistent natural phenomena (e.g., Law of Gravity). - Law
Cells form the basic unit of life. - Organization
The ability to acquire and use energy (e.g., photosynthesis, respiration). - Metabolism
Maintaining internal balance (e.g., body temperature regulation). - Homeostasis
Increase in size and complexity. - Growth & Development
Ability to produce offspring (asexual vs. sexual). - Reproduction
Bio 100
, Bio 100
Reacting to the environment (e.g., plants growing toward light). - Response to Stimuli
Genetic change over generations through natural selection. - Evolution
Fundamental substances (C, H, O, N make up 96% of life). - Elements
Basic unit of matter (protons, neutrons, electrons). - Atoms
Two or more atoms bonded together. - Molecules
Atoms with a charge due to electron loss/gain. - Ions
Sharing electrons (e.g., H₂O, CO₂). - Covalent Bonds
Transfer of electrons between atoms (e.g., NaCl). - Ionic Bonds
Weak attractions between molecules (e.g., DNA strands, water). - Hydrogen Bonds
Water sticks to itself (cohesion) and other surfaces (adhesion). - Cohesion & Adhesion
Stabilizes temperatures in organisms and ecosystems. - High Specific Heat
Dissolves many substances, making it the 'universal solvent.' - Solvent Ability
Ice is less dense than liquid water, insulating aquatic life. - Density & Ice Floating
