Rutgers General Biology 115 Exam1/179 Questions and Answers
Neural Development - -involves gene expression and signal transduction
(nervous system in the brain)
-Neuronal Plasticity - -modifications to nervous system after birth; activity
dependent; "use it or lose it"
-Synapses - -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? - -Stimulus
-What's the second step in the process of memory formation? - -Sensory
Memory
-What's the third step in the process of memory formation? - -Short-Term
Memory
-What's the fourth step in the process of memory formation? - -Long-Term
Memory
-What process is it when you retrieve memory from the long-term memory
into the short-term? - -Long-Term Potentiation (LTP)
-What happens when sensory memory and short-term memory is not
encoded? - -Forgotten
-Long-Term Potentiation (LTP) - -encoding and reencoding memories;
changes the brain (stronger synapses/memory)
-Neuron - -Nerve cell
-Emergence - -the whole is more than just the sum of its parts (ex: H2O)

Organelles
-What's the 10th level of biological organization? (from largest to smallest) -
-Molecules
-Hypothesis - -testable explanation for observations based on available data
-Prediction - -what you expect to see when you test your hypothesis
-Theory - -broad explanation with significant support
-Law - -statement of what always occurs under certain circumstances
-The Scientific Method - -Observation, Hypothesis, Experiment, Data
Collection, Conclusion, and Retest (if needed)
-Electrons (e-) - -a subatomic particle with a negative charge, move rapidly,
determine how element reacts
-What happens when an electron is is excited? - -Moves farther away from
the nucleus, can be used to do work
-Electron Shell - -electron's potential energy
