The ____ group includes guppies, swordtails, mollies, and platies.

Explanation:
Livebearers reproduce by giving birth to live young. Guppies, swordtails, mollies, and platies carry developing embryos inside the female until they are ready to be born, rather than laying eggs. Fertilization is internal, and the offspring emerge as free-swimming fry. That internal, live-birth strategy is what these fish share, which is why they’re grouped as livebearers. Terms like egg-layers, egg-scatterers, or bubble-nest builders describe other reproductive methods that involve laying eggs or nest-building for eggs, not the way these fish reproduce.
