प्रश्न
In markets, eggs of birds are available but never eggs of dogs, why?
उत्तर
Birds are oviparous, i.e. lay eggs outside their body. So, it is easy to collect their eggs and these are thus available in market.
On the contrary, dogs are viviparous, i.e. do not lay eggs but give birth to young ones. Their eggs are extremely small which remain inside their bodies.
