What term describes animals that give birth to live young?

• A. Oviparous
• B. Viviparous
• C. Incubative
• D. Parthenogenetic

Answer: (B)

The term that describes animals that give birth to live young is "viviparous." This term originates from Latin, with "vivus" meaning "alive" and "parere" meaning "to give birth." In viviparous species, the young develop inside the mother's body and receive nutrients directly from her, which allows for a more protected and nourished development compared to those that hatch from eggs. In contrast, the other terms refer to different reproductive strategies. Oviparous refers to animals that lay eggs, where the embryos develop outside the mother's body. Incubative is not commonly used in the context of animal reproduction, and parthenogenetic refers to a form of asexual reproduction where an embryo develops from an unfertilized egg, leading to offspring that are genetically identical to the parent.
