BIO 207 EXAM 3 QUESTIONS & ANSWERS
100% CORRECT (FULLY SOLVED)
alpha diversity - correct answer- diversity within a particular area or
ecosystem
amensalism - correct answer- one population is able to inhibit
growth of another just by existing; gains competitive edge because it's
inhibiting growth of competitor
anabolism - correct answer- synthesis of complex molecule from
simpler parts
ancestry - correct answer- information about the people that an
individual is biologically descended from including their genetic
relationships
atopic march - correct answer- describes common progression of
allergic symptoms from infancy to adulthood; dry skin at birth then
eczema leading to more and more allergies in later stages of life
beta diversity - correct answer- comparison of diversity between
ecosystems, usually measured as the amount of species change between
, the ecosystems; measured in a mount of species change between
person 1 & 2 or location 1 & 2
catabolism - correct answer- breakdown of complex substances into
simpler parts
commensalism - correct answer- one way relationship; one partner
benefits and the other is unaffected; unaffected population either
chemically or physically modifies the habitat in a way that a second
population benefits from it
competitive exclusion/colonization resistance - correct answer-
prevent two populations from occupying same ecological niche since
they cannot play same functional role at same location; one will succeed
(higher growth rate) and other will fail
complex media - correct answer- composed of extracts of chemical
undefined substances (e.g. yeasts and meat extracts)
defined media - correct answer- precise chemical composition is
known
differential media - correct answer- contains an indicator, usually a
dye, that detects particular chemical reactions occurring during growth,
which allows selections of a bacterial colony from a mixed population
