In captivity, tigers and lions have been known to interbreed and produce hybrids, known
as ligers. Why does this NOT make them the same species, according to the biological
species concept? - ANSWER Captivity is not a natural condition
Thomas Malthus's 1798 work, Essay on the Principle of Population, greatly influenced
Darwin. Which of the following statements best summarizes Malthus's idea? - ANSWER
People reproduce much more quickly than their resources do. This results in
competition for food and space, and in suffering and death.
Evolution occurs: - ANSWER only via natural selection, genetic drift, migration, or
mutation
The distribution of terrestrial biomes across the globe corresponds MOST to which of
the following? - ANSWER climate
In humans, genes make up _______________ of DNA. - ANSWER less than 5%
A diploid cell undergoes meiosis. What are the products of this division? - ANSWER
four haploid cells
Which of the following is NOT an example of a testable hypothesis? - ANSWER My
german shepherd is the smartest dog in the world.
Currently, the major threat to most large, land mammals is: - ANSWER deforestation
and habitat loss
Which of the following is an IMPORTANT difference between natural selection and
genetic drift? - ANSWER Natural selection involves differential reproductive success in
the struggle for existence in an environment, while genetic drift does not.
From an evolutionary perspective, behavior can be viewed best as: - ANSWER a trait
that can satisfy the three conditions required for evolution by natural selection.
Roughly how much energy in a trophic level is available to the next trophic level? -
ANSWER 10%
Cancer cells are different from other cells in that they have lost their "contact inhibition."
"Contact inhibition" means: - ANSWER most cells stop dividing when they bump up
against other cells or collections of cells.
,One of the possible concerns about genetically modified foods is that they might kill
organisms that we don't want to kill. Which of the following is an example of this
phenomenon? - ANSWER The pollen from plants containing insect-killing Bt genes can
be blown onto other plants. Insects that we don't want to kill, such as monarch
butterflies, may be killed by such pollen.
Gene therapy involves: - ANSWER introducing non-defective genes into the cells of an
individual with a genetic disorder.
Which of the following structures is NOT found in both plant and animal cells?
A.
plasma membrane
B.
nucleus
C.
lysosome
D.
central vacuole
E.
mitochondria - ANSWER central vacuole
Which of the following bonds is weakest?
A.
ionic
B.
hydrogen bonds
C.
covalent
D.
they all have equal strength - ANSWER B
An isotope is a different form of an atom with a different number of protons. - ANSWER
false
A neon atom has 8 electrons in its outer shell. Neon... - ANSWER is stable
If a food chain consisted of grass to rabbits to foxes, how many pounds of foxes could
be expected in a meadow which has 10,000 pounds of grass? - ANSWER 100
If there are 500 individuals in a population at the start of a year, and during the year 125
offspring are produced in that population, then the annual birth rate is: - ANSWER 0.25
The Gap 1, DNA synthesis, and Gap 2 phases of the cell cycle are collectively called: -
ANSWER Interphase
, The oldest prokaryotic fossils have been dated approximately: - ANSWER 3.5 billion
years ago
The lipids within the fluid mosaic of plasma membranes are held in place by: -
ANSWER hydrophobic and hydrophilic interactions
Which of the following is the primary site of protein assembly within eukaryotic cells? -
ANSWER the ribosomes
Albinism (lack of skin and hair pigmentation) is caused by a recessive autosomal allele.
A woman and man, both normally pigmented, have an albino child together. For this
trait, what is the genotype of the albino child? - ANSWER homozygous recessive
A storm washed five female and five male tiger beetles from the mainland to a small
island that had no previous population of tiger beetles. In tiger beetles, having six spots
(A) is dominant to having four spots (a). All ten beetles had six spots, but one male and
one female were heterozygous for the four-spot trait. If six of the beetles died randomly
without reproducing, the ratio of the genotypes could be quite different in subsequent
generations. This change in allele frequencies would be an example of: - ANSWER
genetic drift
When a species is introduced into a habitat that is not its natural ecosystem, the species
could become invasive. Which of the following is NOT a characteristic of an "invasive"
species? - ANSWER Invasive species never have negative effects on a new habitat's
biodiversity.
Which of the following correctly describes the locations of transcription and translation
within a eukaryotic cell? - ANSWER DNA is transcribed in the nucleus, then the mRNA
transcript is transported to the cytosol to be translated into protein.
The biological species concept is primarily based on: - ANSWER reproductive isolation.
A _______________ is more specific than a hypothesis and can be tested through
experimentation. - ANSWER prediction
A ______________ experiment is one in which neither the experimental subjects nor
the experimenter know which treatment the subject is receiving. - ANSWER double
blind
Evolutionary change as a result of natural selection ALWAYS leads to:
A.
uniformity.
B.
increased complexity.
C.
None of the above is correct.
