1) All populations can be described by fundamental characteristics of their

A. population

density and population distribution

A. (b + i) -- (d + e)

B. N/A

C. N/V

D.ΔN/N

3) The pattern of population distribution found among social animals such a musk-ox would be

C. uniform

D. erratic

4) The planting od apple trees in an orchard to maximize yield, most likely would resemble

A. random population distribution

B. clumped population distribution

C. uniform population distribution

D. a bottleneck population distribution

5) Uniform, clamped, and random patterns of population distributions are influenced by

A. the predator-prey interactions in a community and the effect of parasitism in the population

B. the temperature, availability of water, and nutrients found in the soil of a habitat

C. p + q = 1 ; p2 + 2pq + q2 = 1.00

D. resources in habitat and the interactions among individuals in a population or with other members in a community

6) The four processes that change the number of individuals in population size relative to the original number are

A. natality, immigration, mortality, and emigration

B. birth rate, immigration, migration, and biotic potential

C. large population size, random mating, mutations and genetic drift

D. death rate, emigration, gene flow, natural selection

7) The calculation of the growth rate of a population taking into account the initial size of the population is known as the

A. density of the population

B. per capita growth (cgr)

C. diversity of the population

D. Hardy-Weinberg principle

8) Factors that affect population growth are

A. only biotic factors

B. biogeochemical cycles

C. only abiotic factors

D. both biotic and abiotic factors

9) The highest possible cgr (per capita growth rate) for a population is called its biotic potential. All the following factors determine a species biotic potential (r) except the number of

A. times individuals reproduce in a life span

B. offspring per reproductive cycle

C. high frequency of dominant alleles in the population

D. offspring that survive and reproduce

10) The carrying capacity of the environment is related to factors affecting population growth such as

A. the ratios of the earth's land surface to the volume of the aquatic environment

B. only very small changes in the frequency of alleles from one generation to the next generation

C. availability of water and oxygen, temperature, and relative humidity

D. availability of resources, disease, competition, and predation

11) Drought conditions during the spring seasons prevents the development of large swarms of mosquitoes in summer. This abiotic condition is known as a/an
