Exam 3 (Lab)

Front 1

Allele frequencies stay the same if?

Back 1

if all conditions of hardy-weinberg equilibrium are met.

Front 2

If a population is in Hardy- Weinberg equilibrium and p=6,

Back 2

q=4

Front 3

Natural selection operates directly on

Back 3

the phenotype

Front 4

The process that discriminates between phenotypes with respect to their ability to produce offspring is know as

Back 4

natural selection

Front 5

two populations that have no gene flow between them are likely to

Back 5

become more different with time

Front 6

The process that results in individuals of two populations losing the ability to interbreed is referred to as

Back 6

speciation

Front 7

Two ways in which new alleles can become incorporated in population are

Back 7

mutation and gene flow

Front 8

a shift from expected allele frequencies resulting from chance is know as

Back 8

genetic drift

Front 9

genetic drift is a process that has a greater effect on populations that

Back 9

are small

Front 10

What effect does increasing gene flow between two populations have on their genetic makeup

Back 10

their deneflow will become more similar making it likely to get a specific trait

Front 11

how can selection cause two populations to become different with time

Back 11

each will be subjective to different environmental pressures, the stronger the pressure the more likely and quickly they will become different

Front 12

describe the effects of directional selection can be offset by gene flow

Back 12

the gene would have to be isolated from all other environmental pressures otherwise it will offset gene flow

Front 13

The example "human" is an example of

Back 13

common name

Front 14

current scientific thought places organisms in one of ____ kingdoms?

Back 14

6

Front 15

the scientific name for the ruffed grouse is bonus umbrellas. bonuses is

Back 15

the genus

Front 16

A binomial is always a

Back 16

two part name

Front 17

the science of classifying and aiming organisms is known as

Back 17

taxonomy

Front 18

which scientific name for the wolf is presented correctly

Back 18

Canis lupus (italicized)

Front 19

a road that dichotomizes is

Back 19

a road that forks into two roads

Front 20

most scientific names are derived form

Back 20

Latin

Front 21

one problem with using common names is that

Back 21

1. many organisms may have the same common name

2. many common names may exist for the same organism

3. the common name may not be familiar to an individual not speaking the language of the common name

Front 22

Phylogeny is the apparent

Back 22

ancestors of an organism

Front 23

The advantages of using scientific names rather than common names

Back 23

1. no organism has the same scientific name as another

2. There are not multiple common names for the same organism

3. scientific names are specific to the organism in which anyone who does not speaks the language of the common name can understand

Front 24

some members of the domain bacteria have

Back 24

photosynthetic ability

Front 25

a pathogen is

Back 25

an organism that causes a disease

Front 26

gram stain is used to distinguish between different

Back 26

bacteria

Front 27

organisms capable of nitrogen fixation

Back 27

1. include some bacteria

2. include some cyanobacteria

3. may live as simians with other organisms

Front 28

those organisms that are covered by numerous, tiny locomotory structures belong to phylum

Back 28

alveolata

Front 29

which organism cause "red tides?"

Back 29

dinoflagellates

Front 30

if you found a fish floating on the water covered with white fuzzy material and tiny dark spheres you would suspect that the fish has been infected by a

Back 30

water mold

Front 31

a vector is

Back 31

an organism that transmits a disease causing organism

Front 32

the organism that causes malaria is

Back 32

1. a pathogen

2. Plasmodium vivax

3. carried by a mosquito

Front 33

the cell wall component algin is

Back 33

found in the brown algae

used in the production of ice cream

Front 34

Agar is derived from

Back 34

red algae

Front 35

which is the correct plural form of the word fro the organisms studied in this exercise

Back 35

algae

Front 36

phycobilins are

Back 36

1. photosynthetic pigments

2. found in the red algae

3. blue and red pigments

Front 37

specifically, female sex organs are known as

Back 37

oogonia

Front 38

a reagent that stains the stored food of a green alga black is

Back 38

I2KI

Front 39

The starch production center within many algal cells in the

Back 39

Front 40

a phylum of organisms most closely linked to the evolution of land plants is the

Back 40

sex organs

Front 42

amoebic dysentery is caused by
