Rutgers General Biology 115 Exam 1
Question and answers correctly
solved 2025/2026
Neural Development - correct answer ✔involves gene expression and signal transduction (nervous
system in the brain)
Neuronal Plasticity - correct answer ✔modifications to nervous system after birth; activity dependent;
"use it or lose it"
Synapses - correct answer ✔junction between neurons that tell the brain memories. When broken, the
memory is "lost"
What's the first step in the process of memory formation? - correct answer ✔Stimulus
What's the second step in the process of memory formation? - correct answer ✔Sensory Memory
What's the third step in the process of memory formation? - correct answer ✔Short-Term Memory
What's the fourth step in the process of memory formation? - correct answer ✔Long-Term Memory
What process is it when you retrieve memory from the long-term memory into the short-term? - correct
answer ✔Long-Term Potentiation (LTP)
What happens when sensory memory and short-term memory is not encoded? - correct answer
✔Forgotten
,Long-Term Potentiation (LTP) - correct answer ✔encoding and reencoding memories; changes the
brain (stronger synapses/memory)
Neuron - correct answer ✔Nerve cell
Emergence - correct answer ✔the whole is more than just the sum of its parts (ex: H2O)
Levels of Biological Organization (largest to smallest) - correct answer ✔Biosphere > Ecosystems >
Communities > Populations > Organisms > Organs & Organ Systems > Tissues > Cells > Organelles >
Molecule
BECPO(OS)TCOM - correct answer ✔an acronym for the levels of biological organization
What's 1st the level of biological organization? (from largest to smallest) - correct answer ✔Biosphere
What's 2nd the level of biological organization? (from largest to smallest) - correct answer
✔Ecosystems
What's 3rd the level of biological organization? (from largest to smallest) - correct answer
✔Communities
What's 4th the level of biological organization? (from largest to smallest) - correct answer
✔Populations
What's the 5th level of biological organization? (from largest to smallest) - correct answer ✔Organisms
What's 6th the level of biological organization? (from largest to smallest) - correct answer
✔Organs/Organ Systems
, What's 7th the level of biological organization? (from largest to smallest) - correct answer ✔Tissues
What's the 8th level of biological organization? (from largest to smallest) - correct answer ✔Cells
What's the 9th level of biological organization? (from largest to smallest) - correct answer ✔Organelles
What's the 10th level of biological organization? (from largest to smallest) - correct answer
✔Molecules
Hypothesis - correct answer ✔testable explanation for observations based on available data
Prediction - correct answer ✔what you expect to see when you test your hypothesis
Theory - correct answer ✔broad explanation with significant support
Law - correct answer ✔statement of what always occurs under certain circumstances
The Scientific Method - correct answer ✔Observation, Hypothesis, Experiment, Data Collection,
Conclusion, and Retest (if needed)
Electrons (e-) - correct answer ✔a subatomic particle with a negative charge, move rapidly, determine
how element reacts
What happens when an electron is is excited? - correct answer ✔Moves farther away from the nucleus,
can be used to do work
