Internal fertilization is a process in which the fertilization of an egg by sperm occurs inside the body of a female organism. This typically involves mating or copulation between males and females to transfer sperm to the female reproductive tract for fertilization to occur. Internal fertilization is common in mammals, reptiles, birds, and some fish.
In the fallopian tube and uterus.
Aves, or birds, typically exhibit internal fertilization. In this process, the male bird transfers sperm to the female bird's reproductive tract before the eggs are laid. This adaptation allows for the fertilization of eggs to occur inside the female's body, which can enhance the likelihood of successful development of the embryos. After fertilization, the female lays eggs that develop outside her body.

No, fertilization of the egg by the sperm occurs inside the female reproductive system, typically in the fallopian tubes. The sperm must travel through the female reproductive tract to reach the egg for fertilization to occur.
Generally fertilization occurs in the Fallopian tube but it can occur in the womb.
When a male human sperm is introduced into a female dog's body, it is highly unlikely that fertilization will occur. This is due to the genetic differences between humans and dogs, which make cross-species fertilization extremely rare. Even if fertilization were to occur, the resulting offspring would likely not survive due to the differences in genetic compatibility and gestational requirements between humans and dogs.
Fertilization occurs internally, in the female's reproductive tract, specifically in the fallopian tubes, after mating between male and female mountain gorillas. The sperm from the male gorilla travels up the female's reproductive tract to reach the egg for fertilization.
Fertilization that happens outside the female body is called in-vitro fertilization. In this procedure, the ova is fertilized with the sperm in a laboratory.
External takes place outside the female, as with fish eggs on which the male fish places his sperm. Internal fertilization, in plants and animals, takes place within the organism's structures, where the gametes are joined. In humans, in vitro fertilization (i.e. test tube babies) is a form of external fertilization in that it bypasses the normal occurrence in the fallopian tubes, and then directly implants the fertilized egg(s) in the uterus.
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.
