Question

match each example to one of the processes below.

an area consists of dark and light rocks. mouse populations that live on the dark rocks tend to be darkly colored; mouse populations that live on the light rocks tend to be lightly colored. choose founder effect gene flow genetic bottleneck genetic drift natural selection

a large boulder rolls down a mountain and kills all the flowers in its path. choose

a tourist carries seeds to a new location. these seeds are able to breed with plants of the same species in this new location. choose

overfishing results in an endangered fish population with a very small population size. choose

algae attach to a boat motor and are transported to a new lake where they establish a new colony. choose

Explanation:

First Example:

The example shows mice with color matching their rock environment, a key example of natural selection (adaptation to environment).

A random event (boulder) reduces flower population, fitting genetic drift (random change in allele frequencies).

Seeds (genes) are introduced to a new population, which is gene flow (transfer of genetic material between populations).

Answer:

natural selection
