Individuals moving into and out of the population

Natural disasters killing most of the members of a population

Small changes because of the environment

a mathematical tool that biologists can use to predict allele frequencies and determine whether or not evolution is occurring within a population.

available at local hobby stores and retailers throughout the Greater Tazewell area.

always occurring within individual organisms in nature.

only useful in the lab and cannot be practically applied to real-world populations of organisms.

What is the best explanation for a population being described as an evolutionary unit?

Population can evolve, not individuals

Natural selection only involves individuals, not populations

Genetic changes only occur in populations

A population's gene pool remains the same throughout time

What does the variable q represent?

The frequency of the recessive allele

Frequency of the heterozygote genotype

Frequency of the homozygous recessive genotype

The frequency of the dominant allele

Which of the following is a true statement about natural selection?

variation exists in a population

Which of the following is not involved in natural selection?

differences in reproductive success

inheritable variation in populations

What is suggested by the similarity of early embryos of different species of vertebrates?

evolution from a distant common ancestor

no evolutionary relationships between the groups

similar environments in the past

Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardy-Weinberg equilibrium within a population

A mutation occurs in a particular animal and quickly begins to increase in frequency throughout the population. Which of the following are you most likely to conclude?

The mutation increase the probability that the animal will reproduce.

The mutation makes the animal grow larger

The mutation does not confer any benefit or harm to the animal

The mutation makes the animal more susceptible to predators

Which statement correctly explains how resistance to penicillin appeared after a few years of its widespread use to fight bacterial infection?

some bacteria were resistant to penicillin and their population spread rapidly, without competition from bacteria that were killed by penicillin

in order to survive exposure to penicillin, bacteria developed a resistance to the drug

a few bacteria became resistant to penicillin, and through sexual reproduction , most bacteria acquired the resistance

penicillin never really successfully wiped out populations of bacteria, scientist did not use proper controls in their studies

A species is a group of similar organisms that

can mate with each other and produce fertile offspring.

can live together on an island.

can migrate to an island from the mainland.

all have exactly the same traits.

the preserved remains or traces of organisms that lived in the past

molds and casts of organisms that live today

drawings of ancient animals and other organisms

footprints or burrows of small animals that live today

What did Darwin observe about finches in the Galápagos Islands?

Their beaks were adaptations related to the foods the finches ate.

Their feathers were adapted to match their environment.

They had identical genotypes in all locations.

Their beaks were similar and NOT related to the foods the finches ate.
