NPB 110A Final questions n answers
graded A+
What do animals need to do to be evolutionarily successful? - correct answer ✔✔1. Avoid being
eaten
2. Take care of themselves
3. Successfully reproduce
Superchiasmatic Nucleus - correct answer ✔✔located in the hypothalamus, above the optic
chiasm
Light sensitive retinal ganglion cells (RGCs) - correct answer ✔✔Discovered recently. They
detect light using a pigment called melanopsin. not good for visual details, but ok for encoding
levels of light
Clock genes - correct answer ✔✔Clock genes are sets of instructions that code for clock
proteins. The genes and proteins interact with each other to produce daily fluctuations in
protein levels.
What are the 3 mechanisms involved in epigenetic gene expression? - correct answer
✔✔Modifying packing of DNA, DNA methylation, Non-protein coding RNAs
Type 1 Diabetes - correct answer ✔✔Little or no insulin, make up to 15% of cases and rapid
onset
Type 2 Diabetes - correct answer ✔✔Most are insulin resistant, make up 85% of cases and
gradual onset
, Congenital hyperinsulinism(CHI) - correct answer ✔✔is a disease phenotype characterized by
increased, usually irregular, insulin secretion leading to hypoglycemia, coma, and severe brain
damage, left untreated. 1:50,000 live births.
To study the cellular mechanisms of behavior, it's good to choose - correct answer ✔✔the
simplest possible system
The abdominal ganglion contains the circuit that controls - correct answer ✔✔the gill muscles
Associative learning - correct answer ✔✔involves two different stimuli or actions that are
integrated together.
Non-associative learning - correct answer ✔✔is different, usually involving either a single
stimulus or two non-related one.
The gill withdrawal reflex shows two form of what type of learning - correct answer ✔✔non-
associative
Steps in Generating crawfish Reflex - correct answer ✔✔1)Sense the stimulus
2)Integrate sensory information
3)Reach threshold for reflex
4)Trigger contraction in muscles
When inactivating the LG neuron, what are the electrodes we input? - correct answer ✔✔St,
Rmot, Rlgi, Hyp
Organizational - correct answer ✔✔effects build the system early in development
