Is external fertilization common on land?
Naw
How are external and internal fertilization are different?
internal happens inside the body and in land external happens outside the body and in water
Differentiate between internal and external fertilization?
Internal fertilization occurs inside the female's body, where sperm fertilizes the egg, while external fertilization occurs outside the body, usually in water, where eggs are fertilized by sperm. Internal fertilization is common in land-dwelling animals, while external fertilization is common in aquatic animals. Additionally, internal fertilization provides better protection for the developing embryos compared to external fertilization.
Predict whether an animal that reproduces by external fertilization is more likely to live in water or on land?
The answer is this website SUCKS!
Why do you think there is a basic difference between the kinds of fertilization most common in aquatic and terrestrial animals?
the process of fertilization involves fusion of egg/ova and spermatozoa. the two cells are also called gametes. for their meeting aqueous medium is required. in land animals out side environment is dry therefore fertilization on land is not possible while as genital tract provides similar aqueous atmosphere where spermatozoon swim to reach the egg.
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.
Adaptations in land animals help ensure internal fertilization?
Internal fertilization adaptations in land animals include specialized reproductive organs such as copulatory organs for delivering sperm, behavior changes for mating, and protective structures to safeguard developing embryos. These adaptations are key for successful reproduction on land.
What is the term given to organisms that live both in land and water?
Land organisms and liquid organisms
Which of the animal would you except to have internal fertilization?
Land animals.
Why do animals that undergo fertilization reproduce on land?
Fertilization takes place inside the body. It is directly deposited on the female reproductive system
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.
What evidence is there that land animals mainly carry out internal fertilization?
Sperm cannot fly. Really, it´s that simple. Sperm can´t survive in open air, so it has to be delivered directly to the egg. That´s why we have penises ;) Sperm can survive in water, so fish can just let it all out and let it meet halfway between their bodies. That´s what spawning is; external fertilization.
