BIO 115 FINAL EXAM REVIEW

EXAM 1
ORGANIZERS

Lecture 1: Biology and Learning

1. Process of Learning




2. Types of Memory

Sensory STM LTM
Storage Temporary storage Brief storage of info Permanent storage for
from 5 senses being used currently info not being used at
that moment

Capacity high 7 +/- 2 memories Unlimited

Duration Less than 1 seconds Less than 20 seconds Permanent as long as
for vision and a few LTP is present
seconds for hearing

Type Declarative Attention while in Repetition of info,
knowledge lecture practice


3. Long Term Potentiation
a. Encoding and reencoding of information
b. Facilitates learning
c. Temporal (repetition) and Spatial (connections between diff things)
Summation
d. Is a cyclical process → if you do not recall it, you will lose it
(synapse loses connection)

4. Brain
a. Embryonic development (Neuronal Development): brain develops
and grows before birth
b. Neural Plasticity: Brain is changed after birth (part of ED)
c. Use it or lose it
i. Activity dependent (lots of activity → more connections etc)
5. Themes of Biology




6. Biological Organization (BECPOOTCOMA)

Biosphere All things below are included Example: Earth
Nonliving and living

Ecosystem All communities in a certain area Ex: Savannah
Living and nonliving

Community All diff populations included Ex: lions and zebras
Only living organisms

Population Group of the same organism Ex: pride of lions

Organism One individual in a given population Ex: A single lion

Organ = makes up an organism (made out of Ex:
Organ/Organ tissues) Organ = heart
Organ System = group of organs that work Organ system =
System
together for a specific function digestive system

Tissue Made out of cells that work together for a Ex: muscle tissue
function

Cells Basic unit of life Ex: Blood cell
Cells contain organelles

Organelles Made out of molecules Ex: Mitochondria
Located in cells - each has its own function

Molecules Made out of atoms Ex: H20, O2, H2
In all matter

Atoms Smallest unit of chemical elements Ex: CHON


Lecture 2: Scientific Process/Chemistry

1. Scientific Method




2. Elements of Nucleus

Name Charge Location Role in Atom
Proton (+) Nucleus Identity + mass
Electrons (--) Orbiting nucleus Reactions
Neutrons Neutral Nucleus mass

3. Chemical Bonding
Farther away orbital → more PE (farther away from nucleus)

Nonpolar Covalent Polar Covalent Ionic Bond VDW (HB)

Atoms/mol b/w atoms b/w atoms b/w atoms b/w molecules

Sharing? Equal sharing b/w Unequal Stealing or Interactions
e- sharing b/w e- transferring of b/w molecules
(partial +/-) e-

Strength Strongest Strong Weak Weakest

EN Same <2 >2 N/A

Example CH4 H2O NaCl H2O --- H2O
Cation: loses e-
to become (+)
Anion: gains e-
to become (-)


4. Emergent Properties of Water

Hydrogen Bonding - Bond pairing water molecules together
- Leads to 4 other properties

Cohesive Behavior - Cohesion: ability for H2O molecules to stick to each
other (HB)
- Surface Tension → spider
- Adhesion: H2O molecules adhering to surfaces
- Allows water to travel up from stem

Moderate - High specific heat (hard to change its state)
Temperature - Very hard to change properties of H2O
- Stable environment: allows H2O to not overheat → imp
for aquatic life
- HB hard to break (multiple of them)
- Resist change in temp

Expansion Upon - Structure of H2O changes as it gets colder
Freezing - HB becomes rigid → air pockets form (traps air) → less
dense than liquid
- Ice floats → forms on surface → protects fish
