Answer 2

Answer:

External fertilization is a type of fertilization that occurs outside of the female body and is common in the animal kingdom. The external environment is where the embryo grows and matures.

Explanation:

• Animals that reproduce are referred to be viviparous. In viviparous animals, the female reproductive system is where fertilization and embryo development both take place. The woman gives birth to the child when the fetus has finished developing. The condition in which the embryo gets its nourishment from the mother rather than the yolk is known as matrotrophy.
• Oviparous animals are those that lay eggs. In oviparous species, internal fertilization occurs, but external embryo development occurs.
• Immature embryos are present in the eggs of birds like the hen and the duck. Eggs are shielded from harm by their robust shells. The egg hatches when the fetus is fully developed. Oviparity is the term for an animal's ability to deposit eggs.
