Question

What differences between humanbeings birth babies and hen laying eggs?

Answer 1

humans are viviparous while hens are oviparous.
human babies have full chances of survival as they are protected in the mother's womb.
hens lay eggs which are food for predators.

Answer 2

Answer:

Internal fertilisation is the term for conception that occurs inside the female reproductive system. When it comes to hens, the zygote rapidly divides after fertilisation and moves down the oviduct. Numerous shielding layers are produced around it as it descends. One such protective layer is the thick shell that you can see on a hen's egg. The hen ultimately lays the egg when the developing embryo's hard shell has formed around it. However, in the case of humans, the entire process takes place inside the female body, resulting in immediate childbirth.

Explanation:

In the animal kingdom, there are species that go through the process of fertilisation in two different ways: one is external fertilisation, where the sperm-egg fusion takes place outside the female body, and the other is internal fertilisation, where the sperm-egg fusion takes place inside the female body. Animals are divided into oviparous and viviparous groups based on this.

Oviparous animals:-

• These organisms lay eggs.
• There is evidence of internal fertilisation, but the embryo develops through external mechanisms.
• Once the foetus is developed, the egg hatches out of its hard shell, providing protection.
• Ovarian animals have this trait, which is known as oviparity.
• Birds, frogs, and all fish are examples. Platypus and Echidna are egg-laying mammals, while all other reptiles are oviparous with the exception of several snake species.

Viviparous animals:-

• Animals that give birth to young are referred to as viviparous animals.
• Inside of the female body, the embryo develops and is fertilised.
• Matrotrophy is noticed.
• For examples: Humans, whales, dogs, cats, etc.
