Respuesta :

external would be the answer!

Answer:

The correct answer is "external".

Explanation:

External fertilization is a type of sexual reproduction where the fertilization takes place outside the body of the female organism. This type of reproduction has the advantage that the mother does not need to carry the embryo while it develops. External fertilization is particularly common in aquatic animals, where only sharks and a few types of fish do not reproduce using this adaptation.
