Low plants, lacking vascular tissue:

Mosses

2

One of the first plant groups to have vascular tissues and true roots:

Ferns

3

Larger plants with vascular tissue, fronds, and sperm that swim:

Ferns

4

Produce flowers and seeds:

Angiosperms

5

Produce naked seeds in cones:

Gymnosperms

6

Sepals and petals are present:

Angiosperm

7

Require water for fertilization to occur:

Fern and Moss

8

Produce spores for reproduction:

Fern and Moss

9

Produce naked seeds:

Gymnosperm

10

Able to conduct water up through the stem, often called conifers:

Gymnosperm

11

Pollination occurs:

Angiosperm

12

Contain a stigma, style, and ovary:

Angiosperm

13

One of the tallest plants living:

Gymnosperm

14

Adaptation that protects a living embryo:

Angiosperm

15

Cotyledons provide energy for the newly developing organism:

Angiosperm

16

Classified as nonvascular plants:

Moss

17

Liverworts and mosses belong to this group:

Moss

18

Group of plants that produce flowers:

Angiosperm

19

Fruits are produced by this plant group:

Angiosperm

20

Plants in this group have a symbiotic relationship with algae:

Moss

21

The bones labeled in the figure above are both:

Vestigial body parts

22

Fossils found in the lowest geological strata are generally the most:

Primitive

23

Critical to the theory of evolution, Darwin needed to include an idea that was not generally accepted by the scientists of society at that time. That idea was:

That the Earth must be very old

24

Urban rats have resisted effects to poison them out because they:

Breed rapidly and evolve by natural selection

25

Which of the following evolve?

-Population

-Genera

-Kingdoms

-Individuals

Populations

26

Wings of insects and birds are result of convergent evolution. This means that:

Insects and birds have each independently evolved structures that serve the same function (flight) but have done so in very different ways

27

The presence of vestigial organs supports evidence of evolution because:

The vestigial organ is similar to a functional organ in a related species, having been passed down from a common ancestor.

28

The wing of a bird and the wing of an insect are:

Homologous structures

29

When comparing chick and pig embryos, the similar eyes, pharyngeal pouches, and post-anal tails are evidence of:

Common ancestry

30

Natural selection results in:

Offspring being better adapted to their current environment

31

According to Darwin, natural selection is based on the ______ found in populations:

Variations

32

The fossil record is incomplete because:

-Very few organisms were preserved as fossils

-Organisms tend to decay before becoming a fossil

-Geological processes may destroy fossils

33

The forelimbs of early mammals were similar in all features except:

Function

34

New alleles arise by:

Mutation

35

If the frequency of a recessive allele is 36 percent, the frequency of the dominant allele would be what percent?

64

36

A species is composed of:

Organisms that have the potential to interbreed and produce fertile offspring

37

Which of the following does not generate genetic variation within a population?

Adaptation

38

All of the genes and all of their associated alleles within a population represent the population's:

Gene Pool

39

Dominance causes an allele to become more common:

False

40

In random mating, individuals choose the most attractive mate:

False

41

In the process of natural selection, individuals that are most fit are the ones that are most likely to reproduce:

True

42

Microevolution is the term that applies to small-scale changes over a long period of time:

False

43

Although Lamarck hypothesized that adaptations to the environment did occur, he also believed that offspring inherited characteristics acquired by their parents during their lifetime:

True

44

Lamarck's hypothesis has since been discredited by Darwin's theory of natural selection:

True

45

The observation that different geographical areas sometimes exhibit plant and animal communities of similar appearance, even though the individual plants and animals are not closely related, is called:

Convergent Evolution

46

The key point in Darwin's proposal is that the ______ imposes the conditions that determine the direction of selection:

Environment

47

Natural selection, as a mechanism of evolution that, acts on variants within populations and ultimately leads to the evolution of different species was proposed by:

Darwin

48

Darwin proposed that natural selection occurs in an environment by:

Favoring heritable features that make the organism better suited to survive and reproduce

49

An insect population that becomes resistant to a commonly used insecticide is an example of ______

Natural Selection
