The resistant bacteria change the chemical make up of the antibiotic, rendering it ineffective.

The resistant bacteria grow larger and the antibiotic can no longer work on them

The bacteria that were resistant managed to survive and form a population that is likewise resistant.

The resistant bacteria attack the antibiotic rendering it ineffective

How does the location of the finches affect the length of the beaks?

How does the beak shape of the finches change from one generation to the next?

Is the shape of the beaks of the male finches similar to that of female finches?

What is the relationship between the length of the beaks in comparison to the length of the feet?

An increase in the in fitness of the short necks

A decrease in the in availability of food

An environmental factor which changed the phenotypic distribution of the turtles

A change in the phenotypical distribution of the female turtles

Brown beetles undergo a greater number of unfavorable mutations than green beetles do.

Brown beetles are more fit for the environment than the green beetles are.

Brown beetles have a shorter life cycle than green beetles have.

Green beetles are more fit for the environment than brown beetles are.

The the toxic chemicals on their skin helps them find food in their environment.

The the toxic chemicals on their skin helps them blend in with their environment.

The the toxic chemicals keeps predators away which allows them to survive and reproduce.

The bright colors of the frog helps them attract mates.

Producing more offspring increases the probability that some will survive and reproduce

Producing more offspring increases the probability of developing beneficial mutations in the population

Producing more offspring increases competition between other organisms who eat the same food

Producing more offspring increases the probability that they will evolve into a new species.

Variation increases from mutations.

Variation increases due to gene flow.

Variation decreases due to genetic drift.

Variation does not change.

It decreases diversity, which limits Escherichia coli to a single type of environment.

It decreases diversity, which causes it to reproduce more slowly over time.

It increases genetic diversity, which prevents Escherichia coli from undergoing genetic changes.

It increases genetic diversity, which increases the chances of survival.

Founder Effect

Bottleneck Effect

Gene Flow

Natural Selection

Geographic separation that limited genetic changes.

Good traits that are inherited from parents and passed on to their offspring.

The intentional breeding of cuttlefish by humans to promote specific traits.

Pollution in the environment changed their genetic makeup.

Natural selection

Gene flow

Genetic Drift

Speciation
