BIO 201 EXAM 1 WITH CORRECT
ANSWERS 2025
Anatomy correct answers >> study of structure and how the
structures are related
Physiology correct answers >> study of function
molecules-levels of organization correct answers >> cells
tissue
organs
organ system
organism
chemical
tissue correct answers >> collection of cells with a similar
anatomy and shape
organs correct answers >> structures composed of two or
more tissues
provides specific function
organ system correct answers >> a collection organs that
work together to provide specific function
,homeostasis correct answers >> the condition in which the
body's internal environment remains relatively constant even
when exposed to a changing environment
homeostatic ranges correct answers >> the normal range
safe, functional range of any given physiological parameter
ex. body temperature, insulin levels, glucose levels
sensory receptors correct answers >> detect specific
changes in parameter
relay info to nervous system/endocrine system-analyzes change
and coordinates response
negative feedback loop correct answers >> common
mechanism to maintain homeostasis
self-correcting
self-limiting
ex. regulating body temp.
Positive feedback loop correct answers >> less common
mechanism to maintain homeostasis
self-amplifying
requires outside agent to turn off
ex. birth of a baby
Thermodynamics correct answers >> study of energy
, energy correct answers >> the capacity to do work, make a
change
kinetic energy correct answers >> movement
potential energy correct answers >> stored energy
-chemical energy
-electrical energy
-elastic energy
-gravitational
-heat-low grade, not useful for work
chemical energy correct answers >> 1.chemical bond
2.chemical gradient (high to low)
electrical energy correct answers >> separation of electrical
charge
1st law of thermodynamics correct answers >> energy can't
be created or destroyed, but it can be converted to one form to
another
2nd law of thermodynamics correct answers >> systems flow
to slow energy state (entropy is always increasing)
order/structure---->random/chaos
-organized effort requiring energy input (low to high)
