Binomial Nomenclature is a naming system for species with how many names?

2

100

Genes for traits that help an organism be more successful reproductively can be expected to be _____________ common

more

100

Speciation due to a geographic divide is called

allopatric speciation

100

Evolution that results in speciation is called

macroevolution

200

Which characteristic did Darwin observe about the finches on the Galapagos Islands?

Beaks

200

Organisms are grouped into a five-kingdom classification system based on their structure and their

Evolutionary Relationships

200

Which of the following does NOT increase genetic variation?

a. mutations    

b. mitosis   

c. gene flow     

d. crossing over

mitosis
200

speciation due to behavioral differences is called

sympatric speciation

200

Evolution that results in small changes in the population but the population does not change into a different species is called

microevolution

300

An adaptation is

a trait that helps an organism survive in its environment.

300

According to binomial nomenclature, species are given two names based on their:

genus and species

300

Genetic diversity is ultimately/mainly the result of

mutations

300

Gene Flow changes allele frequencies because it occurs when

members move in or out of a population

300

Ostrich wings, human tailbone and appendix, and whale legs are all examples of

vestigial structures

A population of giraffes lives in a forest with trees of varying heights. Following a flood in the area, all shorter plants were destroyed and only tall trees remain. After many generations, it is noted that giraffes living in this forest have longer necks, on average, than giraffes living in the same forest prior to the flood. 

What type of natural selection has occurred?

Directional

400

Which one of these is most closely related to the organism Harmonia Axyridis and why?

a. Apis mellifera

b. Harmonia yelloritus

c. Scarabaeus sacer

d. Maratus volans

b. Harmonia yelloritus ; They are in the same family, Harmonia 

400

Allele Frequencies in a population can be predicted with a formula called

Hardy Weinberg Equilibrium

400
Two types of Genetic Drift are:

Bottleneck Effect and Founder Effect

400

The bone structure of a human hand compared to the bone structure of a bat's wing is an example of

Homologous Structures

500

Which of the following is most affected by natural selection and why?

Angora Rabbits

Cuties (Tangerines)

Influenza

Poodles

Influenza -- 

The repeated or cyclical nature of flu outbreaks is caused by the natural selection of the virus for traits that allow it to evade the immune system and replicate, a process that actually results in new distinct strains of influenza virus.


In contrast, the other answers are all examples of artificial selection by which the specific variety or breed has been purposely selected for specific traits.

500

What is the correct hierarchy of classification, going from broadest to most specific?

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

500

In a population that is in Hardy-Weinberg equilibrium, the frequency of homozygous recessive individuals is 0.16 What is the percentage of the population heterozygous for this allele?

0.48 or 48%

500

When a population is no longer in Hardy-Weinberg Equilibrium, ____________ frequencies change, which can lead to _____________

allele; evolution

500

A bird's wing compared to a bat's wing is an example of

analogous structures
