What mosquito housefly eagle turtle and dog undergo internal-external fertilization?
External fertilization occurs when sperm and eggs unite in the open, rather than within specialized organs during internal fertilization. Turtles, eagles, and dogs most definitely undergo internal fertilization. Mosquitoes and houseflies, on the other hand, undergo external fertilization.
Is penguin fertilization internal or external?
Penguin fertilization is internal. The male penguin transfers sperm to the female's reproductive tract during copulation.
Does a newt have internal or external fertilization?
Internal
Did beetle is internal or external fertilization?
Beetles typically exhibit internal fertilization. During mating, the male transfers sperm to the female's reproductive tract, where fertilization occurs inside her body. This method allows for greater protection of the developing embryos compared to external fertilization, which is common in some other species.
Do cats have internal fertilization or external fertilization?
Tigers have Internal Fertilization. (occurs inside the body). Tigers copulate frequently and noisily and repeatedly for 5 or 6 days. Each usually take about 20 to 30 seconds. Then the gestation period is 16 weeks.
Do butterflies have internal skeletons or external skeletons?
Butterflies reproduce by internal fertilization and not by external fertilization. Butterflies, like most insects, will then lay the eggs and wait for them to hatch.
Do earthworms use internal or external fertilization?
Earthworms use internal fertilization. During copulation, sperm is transferred from male to female through the male's specialized structures called seminal vesicles. The female then stores the sperm in her spermatheca until she is ready to fertilize her eggs.
Why does organisms that use internal fertilization produces less offspring than the ones that use external fertilization?
Because internal fertilization requires a womb and placenta to protect and nourish the growing embryos - which limits the number of offspring the mother can produce. Laying eggs outside the body means the female can potentially produce many more off-spring, and thus vastly increase the chances of the species survival.
Does a peregrine falcon use external fertilistaion?
No, peregrine falcons do not use external fertilization. They reproduce through internal fertilization, where the male transfers sperm to the female during mating. After fertilization, the female lays eggs, which she incubates until they hatch. This process is typical of most birds, which lay fertilized eggs rather than engaging in external fertilization.
Does barracuda have internal or external fertilization?
the Barracuda likes to live in fresh water and they love to give externally
Where does fertilization take place in a reptile?
In reptiles, fertilization usually takes place internally inside the female's body. Male reptiles deposit sperm inside the female through cloacal contact during copulation. The sperm then fertilizes the eggs within the female's reproductive tract.
DO gray wolves have internal or external fertilization?
Gray wolves have internal fertilization. During mating, the male and female wolves engage in a reproductive process where the male's sperm fertilizes the female's eggs inside her body. This internal fertilization is typical for mammals, including wolves, ensuring the protection and development of the embryos within the female until they are ready to be born.
