Viviparity is the development of young within the body of the mother, where the mother's body supplies all of the nourishment necessary for the development of the foetus. Human beings are a viviparous species. Oviparity is the development of young within an egg which is deposited outside the body of the mother and hatches outside. The nourishment which the infant needs is wholly contained in the egg. Ovoviviparity is a system midway between the two, where an egg is created with nourishment enough for the infant to grow, but it is not laid, but hatches within the body of the mother. To external appearance, an ovoviviparous species appears to be a viviparous one.
A fish is oviparous as it is an egg layer.

The difference between succeeding terms in a sequence is called the common difference in an arithmetic sequence, and the common ratio in a geometric sequence.
The typical time difference between ovulation and menstruation in the menstrual cycle is around 14 days.
The difference between male and female can be determined by physical characteristics such as reproductive organs, secondary sexual characteristics, and genetic makeup.
Whales are viviparous animals
No placenta in viviparous and oviparous but there is placenta in ovoviviparity
Oviparous, ovoviviparous, and viviparous.
Cockroach are three types in reproduction - oviparous, viviparous and ovoviviparous. Most cockroach are oviparous.
No, actually there is a third choice. They are ovoviviparous as their eggs develop internally and they bear live young.
Such animals are called viviparous ore ovoviviparous. Viviparous animals have some sort of placenta through which the young are nourished before birth. Ovoviviparous animals have their unborn young nourihsed by egg yolk; the young are inside an egg, but the egg hatches just before birth, and there is live birth.
Most amphibians are oviparous (lay eggs ) e.g. but some are ovoviviparous or viviparous ( give birth to young ones ) as some salamanders .

No. Ovoviviparous means that the female produces eggs which hatch inside her body, meaning she actually gives live birth. Platypuses are oviparous, which is quite different from being ovoviviparous. They lay eggs, and incubate them for ten days.
No, humans are not ovoviviparous. Ovoviviparity is a reproductive mode found in some animals where the eggs develop inside the female and hatch internally, but there is no known example of this in humans. Humans give birth to live young after internal development of the embryo.
Chicken is oviparous as it lays egg which later on develops in an embryo. In viviparous condition the new organism is directly delivered from the mother an in case of mammals.
