• Deutoplasm is the nutritive material present in the egg for development and nourishment of embryo. It is a non-living portion of the egg.
• Deutoplam is present in the yolk of eggs. Sometimes yolk and deutoplasm are used synonymously.

Amphibious are the animals that can live on water as well as on land.
Oviparous are the animals that lay eggs.
Triploblastic describes the animal having a body composed of three embryonic cell layers as the ectoderm, mesoderm, and endoderm.
Viviparous are animals that give birth to live young one that has developed inside the body of the parent.

Unisexual is where the organism is either male or female.
Oviparous animals are those that lay eggs, with little or no other embryonic development within the mother.
Viviparous are animals that give birth to live young ones.
Hermaphrodite is the one which has both male and female reproductive organs.
So, the correct answer is option B.

Oviparous are the animals that lay eggs and the embryonic development majorly takes place outside the body of the mother. From the options, pigeon and crocodile lay eggs.
Viviparous are the animals that give birth to live young ones that have developed inside the body of the female parent, Of the given options, rat and horse are viviparous.
So, the correct answer is option C.

Oviparous animals lay an egg and the embryonic development takes place outside the human body. Example birds.
While viviparous animals are those that give birth to live young ones. Example human beings.

Vivipary is the development of the embryo inside the body of the mother, eventually leading to live birth.
Carnivorous are animals that feed on animal tissues.
Omnivorous are animals that feed on plant and animals.
Ovipary is the method of reproduction in which eggs are laid and embryos develop outside the mother's body, each egg eventually hatching into a young animal.
So, the correct answer is option D.

Fish lay eggs instead of giving birth to little fish. As the fish grow, they hatch into fry with an attached yolk sac and then mature into fish. The process usually takes around a week to 10 days, although it can vary widely. Cat, dog, and cow can not lay eggs.

• Oviparous organisms produce their offsprings by laying eggs. Their Egg contains an embryo.
• While viviparous organisms produce offspring by giving birth to young ones. They do not lay eggs.

Crow is oviparous. Cat is viviparous. Frog is oviparous. Lizard is oviparous. Dog and cow both are viviparous. Crow and frog both are oviparous.

So the correct option is Crow, Cat.

The correct option is A.

Oviparous animals can reproduce by laying eggs. This is how most fish, amphibians, reptiles, insects, and arachnids reproduce. All birds and monotremes also reproduce like this. But, viviparous animals are born as the live young individuals.

So the correct answer is oviparous.

The correct option is B.
