- Which of the following is not required for a behavioral trait to evolve by natural selection?
An individual's reproductive success depends in part on how the behavior is performed.
In each individual, the form of the behavior is determined entirely by genes.
An individual's genotype influences its behavioral phenotype.
The behavior varies among individuals.
Some component of the behavior is genetically inherited.
- Female spotted sandpipers aggressively court males and, after mating, leave the clutch of young for the male to incubate. This sequence may be repeated several times with different males until no available males remain, forcing the female to incubate her last clutch. Which of the following terms best describes this behavior?
certainty of paternity
- Which of the following sensory receptors is incorrectly paired with its category?
olfactory receptor-electromagnetic receptor
- The transduction of sound waves into action potentials takes place
within the middle ear as the vibrations are amplified by the malleus, incus, and stapes.
as the basilar membrane vibrates at different frequencies in response to the varying volume of sounds.
as the basilar membrane becomes more permeable to sodium ions and depolarizes, initiating an action potential in a sensory neuron.
within the tectorial membrane as it is stimulated by the hair cells.
when hair cells are bent against the tectorial membrane, causing them to depolarize and release neurotransmitter that stimulates sensory neurons.
- The middle ear converts
air pressure waves to fluid pressure waves.
fluid pressure waves to nerve impulses.
air pressure waves to nerve impulses.
fluid pressure waves to air pressure waves.
pressure waves to hair cell movements.
- a air pressure waves to fluid pressure waves.
- b when hair cells are bent against the tectorial membrane, causing them to depolarize and release neurotransmitter that stimulates sensory neurons
- c In each individual, the form of the behavior is determined entirely by genes.
- d polyandry
- e olfactory receptor-electromagnetic receptor

5 True/False questions
Suppose that the number of bird species is determined mainly by the number of vertical strata found in the environment. If so, in which of the following biomes would you find the greatest number of bird species?
tropical rain forest
temperate broadleaf forest → prey on the community's dominant species.
Which of the following is characteristic of most terrestrial biomes?
clear boundaries between adjacent biomes
a distribution predicted almost entirely by rock and soil patterns
annual average rainfall in excess of 250 cm
vegetation demonstrating vertical layering
cold winter months → adding nitrogen-fixing microorganisms to a degraded ecosystem to increase nitrogen availability
Examine the climograph for some major North American biomes. Which two factors influence the distribution of organisms, as shown in this climograph?
The presence of tundra and presence of forested land
Annual mean temperature and annual mean precipitation
The presence of broadleaf and presence of coniferous forest → The length of a food chain is limited by the inefficiency of energy transfer along the chain
Select the correct statement(s) about the genetics of behavior.
Select all that apply.
Behaviors with a genetic component can evolve through natural selection.
Learned behaviors are not subject to genetic influence.
Most behavioral traits are determined by a single gene. → Behaviors with a genetic component can evolve through natural selection.
A recent study of ecological footprints concluded that
it is not possible for technological improvements to increase Earth's carrying capacity for humans.
the ecological footprint of the United States is large because per capita resource use is high.
Earth's carrying capacity would increase if per capita meat consumption increased.
current demand by industrialized countries for resources is much smaller than the ecological footprint of those countries.
Earth's carrying capacity for humans is about 10 billion. → two species that have exactly the same niche cannot coexist in a community.
