ANSWERS
Broca's area - correct answersControls language expression - an area of the frontal lobe, usually in the
left hemisphere, that directs the muscle movements involved in speech.
aphasia - correct answersimpairment of language, usually caused by left hemisphere damage either to
Broca's area (impairing speaking) or to Wernicke's area (impairing understanding).
Esophagus - correct answersA muscular tube that connects the mouth to the stomach.
stomach - correct answerslarge muscular sac that continues the mechanical and chemical digestion of
food
small intestine - correct answersDigestive organ where most chemical digestion and absorption of food
takes place
In which of the following ways do social insects
benefit most from having several types or castes
within the species? - correct answersThe specialized structure of each caste
permits division of labor and greater
efficiency
The greatest diversity of structure and of
methods of locomotion is exhibited in the
individuals of - correct answersa phylum
Of the following, which is an example of a
,mutualistic relationship? - correct answersThe protozoan Trichonympha digesting
wood in the gut of a termite
Evidence that multicellular green plants may
have evolved from green algae is best supported
by the fact that in both - correct answerschlorophylls a and b are photosynthetic
pigments
All of the following statements concerning the
light-capturing reactions of photosynthesis are
true EXCEPT - correct answersIf captured, some of the energy of the
excited electrons is used to split carbon
dioxide into carbon and oxygen.
Which of the following statements best explains
the hypothesis that the development of sexual
reproduction has resulted in acceleration of the
rate of evolution? - correct answersSexual reproduction is more likely to result
in genetic recombination than is asexual
reproduction.
A frog skeletal muscle contracts in response to
an electrical stimulus. Increase of the stimulus
intensity by 50 percent will increase the strength
of response nearly 50 percent. If the intensity is
again increased 50 percent, the response will
increase only about another 25 percent. Further
increase in the stimulus intensity produces no
further increase in response. - correct answersThe fibers of a muscle have varying
, thresholds for response
Nitrogen-containing waste products are excreted
as the result of the metabolism of which of the
following? - correct answersProteins
Deposits of coal in Greenland and the Antarctic
indicate that - correct answersthese regions were once thickly vegetated
Thirst, loss of weight, and sugar in the urine
result from the undersecretion of a hormone by
which of the following glands? - correct answersPancreas
Considering the role of mitochondria in cells,
mitochondria would likely be most abundant in
which of the following? - correct answersCells of the heart muscle
All of the following statements about enzymes
are true EXCEPT - correct answersEnzymes can function only within
living cells.
Which of the following is critical in limiting the
size to which an animal cell may grow? - correct answersThe ratio of cell surface to cell volume
Which of the following best describes the
effect on heart action of the stimulation of the
parasympathetic nerve fibers of the vagus nerve? - correct answersThere is a decrease in the heartbeat
rate.
