BIOL3204 EXAM QUESTIONS AND ANSWERS WITH
COMPETE SOLUTIONS VERIFIED
What is physiology?
How living organisms function ("knowledge of nature")
Is physiology inter related with other disciplines?
Yes
When was the concept of homeostasis made?
1865, the word wasn't established though
What is homeostasis?
Maintenance of relatively constant body conditions through a variety of regulatory
mechanisms (not counting environment changes)
Who made the definition for homeostasis (not the word)?
Claude Bernard (wanted to go into the arts)
Who coined the word "Homeostasis"?
Walter Canon 1929 American
What is Walter Canon best known for?
Medical use of x-rays and emergency theory
What is negative feedback?
Response mechanism opposes direction of change (results in homeostasis). Also shuts
off response loop
Ten great public health achievements in the US 1900-1999
,Healthier moms and babies
Family planning
Vaccination
Control of infectious diseases
Safer and healthier food
Fluoride in drinking water
Seeing tobacco is bad
Motor-vehicle safety
Safer workplaces
Decline in heart disease and stroke deaths
What is science?
Science is a mechanism for learning about natural phenomena through observation and
experimentation, evidence based
What is a hypothesis?
Its testable and an explanatory statement
What is a fact?
Hypothesis supported beyond reasonable doubt
What is theory?
Principle that incorporates facts into a single, coherent, predictive explanation
Characteristics of Science: CONPTT C=?
Consistent= repeatable
Characteristics of Science: CONPTT O=?
, Observable= event or evidence of its occurrence can be observed (does not have to be
literally observed)
Characteristics of Science: CONPTT N=?
Natural= cause can be demonstrated
Characteristics of Science: CONPTT P=?
Predictive= natural cause can be used to make subsequent predictions
Characteristics of Science: CONPTT T1=?
Testable= these predictions are testable (hypothesis)
Characteristics of Science: CONPTT T2=?
Tentative= subject to modification, correction with additional studies (continually refines
understanding)
What is non-science?
Any system of knowledge/ thought that can't be addressed by the scientific method
Examples of non-science?
Religion and cultural norms
What is psuedoscience?
The attempt to portray non-science as science
What is a placebo?
Positive effect from inert substance
What is a nocebo?
Negative effect from inert substance
What is evolution?
Change in organisms over generations (changes in population allelic frequencies)
