The hormone prolactin has varying effects in
many different animal species. All vertebrates
produce prolactin, which is involved in signal
transduction pathways. In mammals, prolactin
stimulates the production of milk in mammary
glands. In fish, prolactin plays an important role
in osmoregulation. In birds, prolactin is
involved in lipid metabolism.
Which of the following best explains the
presence of prolactin in various vertebrate
species? - ANSWERS-Prolactin is a homologous hormone
because it has a common origin but
different functions in various species
,Which of the following best describes the
production of DMSP by coral and coral
symbionts? - ANSWERS-A negative feedback mechanism
that
reverses the environmental change
Which of the following best describes the effect
of temperature on corals' ability to produce
DMSP as shown in Figure 1 ? - ANSWERS-Both juvenile and
adult corals produce less
DMSP at 27°C than at 32°C
Which of the following best describes the
difference between the total amount of DMSP
produced by adults compared to juveniles at the
start of the 32°C trial? - ANSWERS-Adult corals produced 5
times more
DMSP than juveniles produced
In addition to the effect of temperature on
, DMSP produced by corals and their symbionts,
which of the following relationships is also
being considered in this experiment? - ANSWERS-Effect of
additional DMSP produced by
symbionts and the corals' age
Which of the following best describes the
scientists' findings concerning the density of
symbionts presented in Figure 2 ? - ANSWERS-The symbiont
density at 32°C was
different from the density at 27°C on
days 5 and 10 of the experiment
Which of the following best explains the result
of adult corals being exposed to elevated
temperatures for extended periods? - ANSWERS-They are
able to obtain less energy from
their symbionts because the algae have
been expelled
A particular gene has two alleles, a dominant
