BIO 123 STUDY EXAMS GUIDE ALL QUESTIONS
AND ANSWERS SURE A+
✔✔inductive reasoning - ✔✔draws conclusions through the logical process of induction
✔✔Deductive reasoning - ✔✔uses general premises to make a specific prediction
✔✔Molecule - ✔✔2 or more atoms bonded together in a fixed ratio
✔✔Compound - ✔✔2 or more different elements bonded together in a fixed ratio
✔✔Half-life equation - ✔✔# of half-lives= (ln remaining amount)/(ln 0.5)
✔✔List bonds from strongest to weakest - ✔✔covalent, ionic, hydrogen
✔✔Photosynthesis equation - ✔✔6CO2 + 6H2O ------> C6H12O6 + 6O2
✔✔The prokaryotic domains are - ✔✔Bacteria and Archaea
✔✔The Eukaryotic domain is - ✔✔Eukarya
, ✔✔What four major life groups form the Eukarya? - ✔✔Kingdom Plantae, Kingdom
Fungi, Kingdom Animalia, Protists
✔✔The difference between the movement of energy and the movement of chemicals in
an ecosystem. - ✔✔Energy Flow is a one-way process that is lost as heat
Chemical cycling keeps occuring
✔✔What two things does a hypothesis have to be? - ✔✔testable and falsifiable
✔✔Theory - ✔✔an explanation that may be supported, rejected, or modified based on
new evidence
✔✔Hypothesis - ✔✔an educated guess
✔✔What four elements make up 96% of all living matter? - ✔✔C,H,O,N
✔✔Radioactive Isotopes - ✔✔an isotope that is unstable, the nucleus decays
spontaneously and gives off detectible particles and energy
✔✔What is the only subatomic particle that is directly involved in the chemical reactions
between atoms? - ✔✔electrons
✔✔Van der Waals Interactions - ✔✔individually weak and occur only when atoms and
molecules are very close together. When many such interactions occur simultaneously,
however, they can be powerful: Van der Waals interactions allow the gecko lizard
shown here to walk straight up a wall!
✔✔Hydrogen bond - ✔✔a hydrogen atom covalently bonded to an electronegative atom
is attracted to another electronegative atom
✔✔Evolution - ✔✔a process of biological change in which species accumulate
differences from their ancestors as they adapt to different environments over time.
✔✔Four properties of water that are important for life - ✔✔1. Cohesion - water sticking
to itself & Adhesion-
2. Moderation of temperature
3. Expansion upon freezing
4. Solvent properties
✔✔Acid - ✔✔increases the concentration of hydrogen ions; more protons & hydrogen
ions but LESS hydroxides
✔✔Base - ✔✔reduces the concentration of Hydrogen ions; fewer protons &hydrogen
ions but MORE hydroxides
