EXAM 2025
What is Neural Development - Correct Ans-involves gene expression and signal
transduction (nervous system in the brain)
What is Neuronal Plasticity - Correct Ans-modifications to nervous system after birth;
activity dependent; "use it or lose it"
What are Synapses - Correct Ans-junction between neurons that tell the brain
memories. When broken, the memory is "lost"
What is the first step in the process of memory formation? - Correct Ans-Stimulus
What is the second step in the process of memory formation? - Correct Ans-Sensory
Memory
What is the third step in the process of memory formation? - Correct Ans-Short-Term
Memory
What is the fourth step in the process of memory formation? - Correct Ans-Long-Term
Memory
What process is it when you retrieve memory from the long-term memory into the short-
term? - Correct Ans-Long-Term Potentiation (LTP)
What happens when sensory memory and short-term memory is not encoded? - Correct
Ans-Forgotten
What is Long-Term Potentiation (LTP) - Correct Ans-encoding and reencoding
memories; changes the brain (stronger synapses/memory)
What is a Neuron - Correct Ans-Nerve cell
What is Emergence - Correct Ans-the whole is more than just the sum of its parts (ex:
H2O)
What are the Levels of Biological Organization (largest to smallest) - Correct Ans-
Biosphere > Ecosystems > Communities > Populations > Organisms > Organs & Organ
Systems > Tissues > Cells > Organelles > Molecule

Organelles
What's the 10th level of biological organization? (from largest to smallest) - Correct Ans-
Molecules
Hypothesis - Correct Ans-testable explanation for observations based on available data
What is a Prediction - Correct Ans-what you expect to see when you test your
hypothesis
What is a Theory - Correct Ans-broad explanation with significant support
What is a Law - Correct Ans-statement of what always occurs under certain
circumstances
What is The Scientific Method - Correct Ans-Observation, Hypothesis, Experiment, Data
Collection, Conclusion, and Retest (if needed)
Biology
, Biology
What are Electrons (e-) - Correct Ans-a subatomic particle with a negative charge,
move rapidly, determine how element reacts
What happens when an electron is is excited? - Correct Ans-Moves farther away from
the nucleus, can be used to do work
What is a Electron Shell - Correct Ans-electron's potential energy
What is a Valence Shell - Correct Ans-the outermost shell- where the bonds between
electrons form
What is CHON - Correct Ans-the 4 main elements in Biology (Carbon, Hydrogen,
Oxygen, Nitrogen)
What is a Molecule - Correct Ans-compound with 2 or more atoms
What is Energy - Correct Ans-capacity to cause change or perform work
What is Electronegativity - Correct Ans-affinity for electrons; tendency of an atom go
attract electrons
In terms of biology, which element has the highest electronegativity? - Correct Ans-
Oxygen
What is Covalent Bond - Correct Ans-sharing of electrons between atoms
What is Ionic Bond - Correct Ans-stealing of electron between atoms, Polar, anion and
cation, salts
What is a Nonpolar Covalent - Correct Ans-same electronegativity = share e- equally
What is a Polar Covalent - Correct Ans-<2 difference in electronegativity = share e-
unequally
What is a Cation - Correct Ans-positive ion
What is a Anion - Correct Ans-negative ion
What is a Hydrogen Bond - Correct Ans-VERY STRONG dipole-dipole interactions;
holds water together (polarity causes attractions w/ eachother)
What are Van Der Waals - Correct Ans-develop because electrons are in constant
motion
Involves hydrogen bonds and london dispersion forces
