a video that shows
a penguin that is
laying eggs
a video that shows
a large river that
has penguin
populations on
both sides
a video that shows
penguin species
that have different
mating dances
a video that shows
penguins with
different
reproductive
cycles living
together

Explanation:

Geographic isolation involves physical barriers (like rivers) separating populations. The first option is about reproduction, the third about behavioral isolation (mating dances), the fourth about temporal isolation (reproductive cycles). The second option has a river (geographic barrier) with penguin populations on both sides, showing geographic isolation.

Answer:

a video that shows a large river that has penguin populations on both sides
