Why is internal fertilization considered more advantageous than external fertilization?
Internal fertilization is considered more advantageous than external fertilization for various reasons. The unborn baby is protected in the internal fertilization from any external threats.
Why are there more egg and sperm cells produced during external fertilization than during internal fertilization?
Why are there generally more eggs and sperm cells produce during external fertilization thean internal fertilization
Is external or internal fertilization more common in terrestrial animals?
no it i very rare
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.
What fertilization is most common among terrestrial animals?
Yes, internal fertilization is a reproductive strategy used by virtually all terrestrial animals. In aquatic environments, external fertilization is much more common.
Which of internal and external fertilization is more efficient?
Internal since it limits the space in which the sperm and egg are found in. Fewer eggsare produced by the female conserving raw materials and energy. The male still produces a tremendous amount of sperm but it is less than what is wasted in external fertilization. The offspring are afforded more protection by the mother so fewer are produced
Do mouse internal or external fertilization?
There is a difference. Internal feritilisation takes place in the female's body while external fertilisation does not. External fertilisation usually requires a medium such as water, which the sperms can use to swim towards the egg cell. External fertilisation usually occur in fish and amphibians. Internal fertilisation occurs in mammals, insects, birds, reptiles.
What are the advantages of internal fertilization?
internal fertilization is, by definition advantageous because it is natural. In Vitro fertilization is advantageous for those who cannot have children naturally because it allows the miracle of birth to occur.
How does the number of eggs relate to the type of fertilization?
Usually, it doesn't. The only thing that would be different is that internal fertilization, there is less eggs because they are protected in the mother's body. The external fertilization, there is more eggs because of the lesser chance of survival
What are the similarities of internal external fertilization?
Internal fertilization takes place inside the body of the female. It is necessary for animals which live on land (terrestrial animals) and is retained by aquatic animals descended form terrestrial ancestors eg whales and dolphins. External fertilization takes place outside the body of the female. It usually takes place in water, usually the environment in which the animal lives eg fish and amphibians. This is because eggs and sperm would dry out and die if they are not kept wet. Internal fertilization is more certain than external fertilization so fewer eggs need to be produced. After internal fertilization eggs can be protected and fed while developing inside the mother's body. After external fertilization the eggs are potentially exposed to predators and so must either be produced in very large numbers or protected by the parents or both.
Which forces are easier to anticipate and design for internal or external?
can some one write the reason for why external or internal?
Why might internal fertilization be useful adaptation for life on land?
Internal fertilization is a useful adaptation for life on land. This is because the embryo can develop in an aqueous environment where oxygen is more available and nutrients are more soluble.
