Rutgers General Biology 115 Exam 1
Study Guide Exam with Actual
Detailed Answers 2025/2026.
Neural Development - Answer involves gene expression and signal transduction (nervous
system in the brain)
Neuronal Plasticity - Answer modifications to nervous system after birth; activity dependent;
"use it or lose it"
Synapses - 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? - Answer Stimulus
What's the second step in the process of memory formation? - Answer Sensory Memory
What's the third step in the process of memory formation? - Answer Short-Term Memory
What's the fourth step in the process of memory formation? - Answer Long-Term Memory
What process is it when you retrieve memory from the long-term memory into the short-term?
- Answer Long-Term Potentiation (LTP)
What happens when sensory memory and short-term memory is not encoded? - Answer
Forgotten
Long-Term Potentiation (LTP) - Answer encoding and reencoding memories; changes the
brain (stronger synapses/memory)
Neuron - Answer Nerve cell
Emergence - Answer the whole is more than just the sum of its parts (ex: H2O)
Levels of Biological Organization (largest to smallest) - Answer Biosphere > Ecosystems >
Communities > Populations > Organisms > Organs & Organ Systems > Tissues > Cells >
Organelles > Molecule

Hypothesis - Answer testable explanation for observations based on available data
Prediction - Answer what you expect to see when you test your hypothesis
Theory - Answer broad explanation with significant support
Law - Answer statement of what always occurs under certain circumstances
