Question 4

Epiphytes

Answer 4

Plants that grow entirely on other plants such as lichen and Moss.

Question 5

Kin selection

Answer 5

A form of natural selection that favors traits to increase survival or reproduction of an individual’s kin at the expense of the individual.

Question 6

Innate behavior

Answer 6

A type of behavior that is inherited and does not need to be learned, it is typical of a species.

Explains how things happen in a neurological, muscular, and skeletal sense. For example how do birds fly?

Question 8

Ultimate causation

Answer 8

Explains why things happen from an evolutionary history. For example why you hummingbirds prefer the color red?

Dead or decaying matter eaten by animals.

Where the river meets the ocean and freshwater mixes with salt water.

Question 14

Invasive species

Answer 14

And exotic species that takes over an area and flourishes while harming other native species, like the zebra muscle.

Question 15

Mono phyletic group

Answer 15

And evolutionary unit that includes all it’s ancestral population and all descendants of no other group.

Question 16

Convergent evolution

Answer 16

The independent evolution of analogous traits in the distantly related organisms due to adaptation in similar environments and a similar way of life.

Question 17

Homology

Answer 17

Where organisms of different species share common characteristics such as proteins, DNA, and body parts.. This suggests a shared/common ancestry.

Question 18

Hox gene

Answer 18

A master homeotic gene that controls structure sequence.

Question 19

Ecological niche

Answer 19

The role that a species plays in its environment and the rang of resources it uses.

Question 20

Extinction

Answer 20

When a species completely dies off due to natural causes or man intervention.

Question 21

Sympatric speciation

Answer 21

The divergence of populations living within the same geographic region into different species

Question 22

Post zygotic isolation

Answer 22

Reproductive isolation that results from mechanisms that operate after mating has occurred such as sterility or weakness

Question 23

Prezygotic isolation

Answer 23

The reproductive barrier that prevents organisms from mating.

Question 24

Behavioral isolation

Answer 24

A prezygotic barrier in which organisms cannot mate because they have different courtship rituals.

Question 25

Allopatric speciation

Answer 25

When two species cannot mate because they are completely geographically seperated, such as on two different islands.

Question 26

Temporal isolation

Answer 26

A prezygotic barrier in which species do not mate because they mate at different times in the year.

Question 27

Disruptive selection

Answer 27

A type of natural selection in which both extreme phenotype are favored over intermediate ones.

Question 28

Directional selection

Answer 28

A type of natural selection in which one extreme phenotype is favored over the other and the intermediate.

Question 29

Stabilizing selection

Answer 29

A type of natural selection in which intermediate phenotypes are favored.

Question 30

Vestigial structure

Answer 30

A rudimentary structure with little or no known function that reflects evolutionary history

Question 31

Gene flow

Answer 31

The movement of alleles between populations. It occurs when individuals leave one population, join another and breed.

Question 32

Selfish allele

Answer 32

An allele that benefits an individual rather than the population.

Question 33

Biological fitness

Answer 33

The ability of an individual to produce viable offspring.

Question 34

Sexual selection

Answer 34

A pattern of natural selection that favors individuals with traits that increase their ability to obtain mates.

Question 35

Generic bottleneck

Answer 35

A type of genetic drift in which the population/allele frequency is drastically decreased due to environmental factors.

Question 36

Founder effect

Answer 36

A type of genetic drift in which a population is moved to/started in a new environment.

Question 37

Typological thinking

Answer 37

The idea that organisms are unchanging and if they do change, it is unimportant.

Question 38

Acclimation

Answer 38

Changes in an individual’s phenotype that occur in response to changes in environmental conditions.
