Law of independent assortment
Theory of acquired characteristics
Theory of artificial selection
Theory of relative fossil-dating
3
Separated members of a species developing different traits over a long period of time is called
convergent evolution
divergent evolution
natural selection
survival of the fittest
4
You suggest that the presence of salt could inhibit the growth of bacteria. This is a(an):
Experiment
Observation
Conclusion
Hypothesis
5
The max number of individuals in a population that can survive on available resources is the:
fossil
limiting factor
carrying capacity
radiometric dating
6
Over many generations, unrelated species may come to resemble each other due to
competition with each other
homologous structural adaptations
similar genetic mutations
similar environmental factors
7
Studying the differences b/t fossils & modern organisms helps scientists better understand the
role of mutation in life functions
adaptation of organisms through acquired traits
evolution of organisms over time
primary function of macromolecules
8
The reason we can see change in bacteria in a relatively short period of time is that
travelers carry bacteria around the world
bacteria are very small
there are many different types of bacteria
bacteria reproduce rapidly
9
Some elms are more resistant to a destructive fungal infection than other elms. Why?
Resistant trees produce frequent mutations
Resistant trees gain resistant properties from the soil
Resistant trees have beneficial variations of some genes
Resistant trees form a symbiotic relationship w/ the fungus
10
The fossil record supports which of the following descriptions of evolution of life on earth?
Life first appeared with the diversity found today
Large organisms appeared before single-celled organisms
Complex organisms evolved from more simple organisms
The importance of natural selection diminished over time
11
Which is the best scientific evidence that mammals evolved from reptiles?
Similarities in lifespans of mod. reptiles and mod. mammals
Similarities in diets of extinct reptiles and modern mammals
Fossils of old reptiles & mammals found in same rock layer
Fossils tht sho gradual change in skull shape fr. rep to mam
12
Extinction of a species could result from
fewer unfavorable mutations in the species
evolution of behavior that causes more reproductive success
limited genetic variability in the species
synthesis of a hormone that controls cellular communication
13
Which observation of finches by Darwin contributed to his theory of evolution?
Individuals within a population may vary widely
Populations remain stable over time
Species produce more offspring than can survive
Environmental resources are limited
14
The populations of finches which Darwin studied on the Galapagos Islands provide examples of:
acquired traits
divergent evolution
coevolution
convergent evolution
15
Which is evidence to support the idea that two different species might have a common ancestor?
Their methods of respiration are alike
Their fossils were discovered in the same location
Many of their genes are the same
They use the same means of locomotion
16
Ideas speculating that organisms changed over time, forming new organisms, led to the theory of
environmentalism
selection
evolution
biochemical change
17
Darwin's explanation for evolution was dependent on which scientific concept?
The relationship between size and survival
The ability of organisms to learn
The existence of variations in a population
The significance of social behaviors to survival
18
Which best explains why the sugar glider and flying squirrel both have the ability to glide?
Both evolved at the same time in geologic history
Both learned to glide by imitating the same kinds of birds
Both interbred and blended their gene pools in the past
Both adapted to similar niches where gliding inc. survival
