Answer 1

Answer:

Viviparous and Oviparous Animals

Some animals give birth to young ones while some animals lay eggs which later develop into young ones. The animals which give birth to young ones are called viviparous animals. Those animals which lay eggs are called oviparous animals. The following activity will help you understand better and differentiate between viviparous and oviparous animals.

The eggs of a few animals are easy to collect because their mothers lay them outside their bodies. These animals from which you have collected the eggs are examples of oviparous animals. But you would not be able to collect the eggs of a dog, cow or cat. This is because they do not lay eggs. The mother gives birth to the young ones. These are examples of viviparous animals.

Oviparous animals undergo external fertilisation, while viviparous animals undergo internal fertilisation.The zygote undergoes rapid division after fertilisation and moves down the oviduct. During this period, many protective layers form as a hard shell around the developing embryo.The chick hatches from the egg after three weeks.
