typically used as evidence. Which of the following responses is the most accurate? -
answer"The data are used to support or reject a hypothesis."
Which of the following biomes is characterized by long winters and short summers,
snow as the predominant form of precipitation, soil that is acidic and poor in nutrients,

One strand of a certain segment of DNA has the following nucleotide sequence.
5 prime, A G A T G T C C A G T A, 3 prime5′−AGATGTCCAGTA−3′5′-
AGATGTCCAGTA-3′
The complementary strand in the same segment of DNA most likely has which of the
following nucleotide sequences? - answer3-'TCTACAGGTCAT-5'
The overall process of aerobic cellular respiration is best described as the oxidation of
glucose to produce carbon dioxide and the reduction of oxygen to produce which of the
following? - answerWater
A student uses stationary fans to investigate the effect of wind on water loss by plants.
The student divides the plants into three treatment groups and places each group in
front of a fan. The student sets the fan for each group to one of three different levels:
low, medium, or high. After 24 hours, the student determines the amount of water that
was lost by each plant. To create a bar graph of the results, the student should make
the height of each bar represent which of the following? - answerThe average water
loss for each treatment group
Interphase is the part of the cell cycle that includes which of the following? -
answerReplication of DNA
, A model of secondary succession typically includes which of the following? -
answerChanges in species composition over time
Which TWO of the following are typically present in a bacterial cell but not in a virus? -
answerRibosomes and DNA
Wind turbines are used for which of the following activities? - answerGenerating
electricity without burning fossil fuels
The nucleotides of a single strand of DNA are linked together by which of the following?
- answerPhosphodiester Bonds
Which of the following pathways is common to both fermentation and aerobic cellular
respiration? - answerGlycolosis
In a germinating seedling, the root grows downward into the soil. Which of the following
correctly explains this phenomenon? - answerThe root exhibits positive gravitropism.
Which of the following best describes the role of transpiration in the water cycle? -
answerIt moves water from the soil to the atmosphere.
In which of the following cell types is a mutation most likely to have an impact on the
gene pool of a population? - answerSperm
Which of the following actions will best help maintain the diversity and abundance of
organisms in a terrestrial ecosystem? - answerPreventing habitat destruction
A population of a certain animal species is found in a protected wildlife preserve. Which
of the following poses the greatest threat to the long-term survival of the population? -
answer
Which of the following describes the primary function of bone marrow in humans? -
answer
Which of the following is the best example of habitat fragmentation? - answer
Ether can be used to anesthetize fruit flies. The flies are typically anesthetized in an
etherizer, a small chamber that contains an absorbent material onto which a few drops
of ether are placed before the flies are introduced. Ether is volatile and highly
flammable. In which of the following locations should the ether be added to the
etherizer? - answer
A diploid organism has the genotype uppercase A, lowercase a, uppercase B,
lowercase b, uppercase C, lowercase cAaBbCc in regard to three unlinked genetic loci.
