The difference between viviparous and oviparous animal is

Explanation

In Biology, animals can be classified into two groups based on how they give birth: viviparous and oviparous. Viviparous animals give birth to live young, while oviparous animals lay eggs. The difference between these two groups of animals is explained in this question. The question asks us to identify the difference between viviparous and oviparous animals. The options given are possession of yolked eggs, laying and brooding of eggs (correct answer), possession of yolkless egg and laying of unfertilized egg. The correct answer is option B, which states that oviparous animals lay and brood their eggs. This means that the eggs are fertilized outside the mother's body and then laid outside. The mother then broods over the eggs, providing warmth and protection until they hatch. In contrast, viviparous animals retain the fertilized eggs within their body and give birth to live young. It is important to note that not all oviparous animals lay eggs in the same way. Some lay eggs with a lot of yolk, while others lay eggs with very little yolk. The amount of yolk in the egg determines how much nutrition the embryo will have to sustain itself until it hatches. In conclusion, the difference between viviparous and oviparous animals is that oviparous animals lay and brood their eggs, while viviparous animals give birth to live young.
