Final Review

What is the study of population?

• demography

• survivorship

• migration

• age structure

What can occur if a population has plenty of food and space, and has no competition or predators?

• reducing of carrying capacity

• zero population growth

• exponential growth

• coevolution

A male has which of the following chromosomes?

• XY

• YY

• X

• XY

The basic facilities of ages in a specific population at a certain time.

• arable land

• infrastructure

• urbanization

• age structure

The functional role of a species within an ecosystem.

• carrying capacity

• symbiosis

• niche

• dispersion

In Mexico the population in 2000 was 50,000. During the year, there were 225 births, 80 migrants, and 45 deaths. What is the population at the beginning of 2001.

• 48,446

• 49,220

• 50,250

• 50,260

Is this trait heterozygous, homozygous dominant, or homozygous recessive: FF

• heterozygous

• homozygous recessive

The ratio of births to deaths in a population.

• carrying capacity

• density

• growth rate

• dispersion

• commensalism

• parasitism

• symbiosis

An organism's genetic makeup or allele combination.
