,Silent Substitution - correct answers ✔✔Occur becuase of the redundancy of
the genetic code
Point Mutation - correct answers ✔✔Occur when a single nucleotide is
changed within a gene
Frameshift Mutation - correct answers ✔✔Can have three different outcomes
arising from the alteration of the triplet-codon reading frame.
Insertion Mutation - correct answers ✔✔Occurs from the gain of nucleotides
within a gene
Endocrine Signaling - correct answers ✔✔Long-term signaling that regulates
blood pressure, blood volume and energy metabolism.
Autocrine Signaling - correct answers ✔✔Local signaling where the ligand is
not transported trough the blood but instead diffuses across a short
distance.
Synaptic Signaling - correct answers ✔✔Local signaling where the ligand
diffuses across a synapse
Pheromone Signaling - correct answers ✔✔Ligands are released into the
external environment to mark territory or attract mates.
Falling Phase - correct answers ✔✔K+ ions flow out of the cell, making the
cell more negative
,Depolarization - correct answers ✔✔Na+ ions flow out of the cell,
Rising Phase - correct answers ✔✔Positive feedback causes opening of more
Na+ channels
What is homeostasis - correct answers ✔✔The tendency to maintain an
equilibrium or set point, among interdependent physiological processes
despite environmental changes.
Absorption - correct answers ✔✔The process of a drug moving from its site
of administration to the target area, crossing one or more body membranes
Active Surveillance - correct answers ✔✔Health officers or other public
health officials execute procedures to gather pertinent health data.
Advantage - greater level of accuracy. Disadvantage - more man power,
more expensive.
Passive Surveillance - correct answers ✔✔Techniques in which data reporting
is mandated or requested. Existing data is identified , counted and reported.
Advantage - easy and inexpensive. Disadvantage - providers may not submit
detailed reports.
Which sequence immediately stops transcription - correct answers
✔✔Polyadenylation Sequence
Excitatory neurotransmitters ____ the electrical threshold by increasing
electrical excitability of ____ cells, allowing action potentials to be
propagated more quickly. - correct answers ✔✔Decrease, post-synaptic
, What are the two main ways neurotransmitters are cleared from the
synapse? - correct answers ✔✔Inactivating enzymes and reuptake via
neurotransmitter transport channels.
Chemoreceptors - correct answers ✔✔Restore homeostasis through negative
feedback, but they do not communicate with the hypothalamus as they are
reflexive.
Post-Marketing Phase - correct answers ✔✔Phase of drug development
process covers expansive groups of people with diverse medical backgrounds
as adverse effects may not appear until larger numbers of people begin
taking a drug.
Preclinical Phase - correct answers ✔✔Exhaustive laboratory work, 1-3 years
long. Cells are grown in culture and the candidate drug is tested to look for
potential harms. Animal testing would occur now.
Clinical Investigation Phase - correct answers ✔✔2-10 years long.
Pharmacologists gather data , important in identifying adverse SE and
possibility that developing drug may worsen other conditions. Clinical trials
occur during this phase.
New Drug Approval Phase - correct answers ✔✔Formal review process
conducted by a specialized branch of the FDA. 2 months - 7 years. Clinical
data is examined. If the drug has reasonable benefit it can continue to post
marketing studies.
Epidemiological Triad - correct answers ✔✔Focuses on interactions among
host, agent, and environment.
