Bio 167 Final UPDATED ACTUAL Exam
Questions and CORRECT Answers
Sexual reproduction includes a reproductive pattern called _____.
fragmentation
budding
fission
hermaphroditism
regeneration - CORRECT ANSWER - hermaphroditism
Animals utilizing external fertilization are typically _____.
insects
animals that reproduce asexually
aquatic animals
land animals
mammals - CORRECT ANSWER - aquatic mammals
Sexual reproduction
allows animals to conserve resources and reproduce only during optimal conditions.
enables males and females to remain isolated from each other while rapidly colonizing habitats.
yields more numerous offspring more rapidly than is possible with asexual reproduction.
, can produce diverse phenotypes that may enhance survival of a population in a changing
environment.
guarantees that both parents will provide care for each offspring. - CORRECT
ANSWER - can produce diverse phenotypes that may enhance survival of a population in
a changing environment.
Environmental cues that influence the timing of reproduction generally do so by
increasing the body temperature.
increasing the ambient temperature to that which is comfortable for sex.
causing direct effects on hormonal control mechanisms.
providing access to water for external fertilization.
causing direct effects on gonadal structures - CORRECT ANSWER - causing direct effects
on hormonal control mechanisms.
Which of the following patterns of reproduction are found only among invertebrate animals?
pheromonal and hormonal coordination
hermaphroditism and parthenogenesis
external and internal fertilization
,fission and budding
sexual and asexual reproduction - CORRECT ANSWER - fission and budding
In close comparisons, external fertilization often yields more offspring than does internal
fertilization. However, internal fertilization offers the advantage that
it permits the most rapid population increase.
it requires expression of fewer genes and maximizes genetic stability.
it requires less time and energy to be devoted to reproduction.
the smaller number of offspring produced often receive a greater amount of parental investment.
it is the only way to ensure the survival of the species. - CORRECT ANSWER - the
smaller number of offspring produced often receive a greater amount of parental investment.
External chemical signals that coordinate potential reproductive partners are called
cytokines.
hormones.
gametes.
pheromones.
paracrine signals. - CORRECT ANSWER - pheromones.
, Sperm cells are stored within human males in the
prostate.
epididymis.
urethra.
seminal vesicles.
bulbourethral gland. - CORRECT ANSWER - epididymis.
Human sperm cells first arise in the
epididymis.
vas deferens.
prostate gland.
Sertoli cells.
seminiferous tubules. - CORRECT ANSWER - seminiferous tubules.
Mature human sperm and ova are similar in that they
are formed before birth.
