BIO 110 EXAM 1 (CHAPTERS 1-3) QUESTIONS AND ANSWERS | COMPLETE
BIOLOGY EXAM 1 STUDY GUIDE 2026/2027
What Is Biology? - ANS ✔✔Is the study of living forms- bacteria, fungus, plants, or even you.
What is the correct sequence of smallest unit to largest unit in Biological organizational hierarchy. - ANS
✔✔atom - molecule -organelle - cell - tissue - organs - organ systems - individual organisms - populations
- communities - ecosystems - biosphere
What is a primary producer? - ANS ✔✔Its when they extract energy and nutrients from the nonliving
environment.
What is Homeostasis? - ANS ✔✔process by which organisms maintain a relatively stable internal
environment
What is Life's three domains? - ANS ✔✔Bacteria, Archaea, and Eukarya
What is the difference between independent variable and dependent variable? - ANS ✔✔Independent
Variable is when something is being manipulated in an experiment, and Dependent Variable is when
something is being measured in an experiment.
What is a control group? - ANS ✔✔The group that does not receive the experimental treatment in an
experiment.
What is the experimental group? - ANS ✔✔the group in an experiment that receives the variable being
tested
What is a difference between a hypothesis and a prediction? - ANS ✔✔A hypothesis is a statement that
can be tested. A prediction is a guess of the outcome of the experiment.
What is a element? - ANS ✔✔A substance that cannot be broken down into simpler substances
What is the difference between ionic and covalent bond? - ANS ✔✔Covalent is the sharing of electrons
and Ionic is the transfer of electrons from one element to another element.
What is cohesion? - ANS ✔✔an attraction between molecules of the same substance
What is adhesion? - ANS ✔✔An attraction between molecules of different substances
What is a organic molecule? - ANS ✔✔a molecule that contains carbon and hydrogen
What is a polymer? - ANS ✔✔long chain of monomers
What is a monomer? - ANS ✔✔a molecule that can be bonded to other identical molecules to form a
polymer.
