Question

Animals who give birth to young ones are?

Answer 1

Hint: These are the animals that give birth to young ones of their own kind. The growth of the young ones takes place inside the body of the female animal and a fully developed embryo is developed.

Complete answer:
Viviparous are organisms that give birth to young ones of their kind for instance humans. The young ones are developed inside the mother's uterus (womb) this period is known as gestation and birth. After the young one is being born still it requires care and nourishment. Thus the infant is protected from the external harsh temperature or any other external factors.
Thus the correct answer is Viviparous (organisms that give birth to young ones of their kind for instance humans).

Additional Information: Oviparous animals are those organisms that lay eggs for instance frogs, snakes, lizards, hens, ducks, fishes, sharks, penguins, butterflies, octopuses, etc.
Oviparous animals fertilized eggs have calcareous shells and young ones hatch out after a period of incubation (growth phase). This calcareous shell protects the young ones from the outside environment. In contrast to viviparous, this shell protection is not present as the fertilized egg (zygote) develops inside the body of the female organism.
Thus the correct answer is Viviparous (organisms that give birth to young ones of their kind for instance humans).
Ovoviviparous are those organisms producing eggs that develop within the maternal body (as of various fishes or reptiles) and hatch within or immediately after release from the parent eg:- sharks, rays, snakes, fishes, and insects.

Note: Viviparous and ovoviviparous animals are different. Viviparous animals are those organisms that give birth to young ones and ovoviviparous animals producing eggs that develop within the maternal body.
