What statements about vertebrates is true?
The development of an amniotic egg and internal fertilization allowed vertebrates to reproduce away from water.
Why is fertilization internal for humans?
Human evolution goes back from mammals (what we are) to reptiles. One of the huge breakthroughs in the sucess of reptiles was adapting to a land existence. This included both internal fertilization and the amniotic egg (prior to this (by and large) animals shed their gametes into the water.. Our fertilization is internal because via the processes of evolution and adaptation that shapes all life on this planet yielded internal fertilization as a way to live on land yet still be able to keep the gametes (sperm and egg) from drying out. Like your private parts...thank a reptile!
How do animals fertilize plants?
Internal fertilization and external fertilization. Internal fertilisation means fertilize the egg inside the female's body. External fertilization is fertilize the egg after the female had lay it out. All mammals including platypus and spiny anteater do internal fertilization.
How is an amniotic egg important adaptation for reptiles?
The amniotic egg allows reptiles to reproduce on land, away from water.
What are two crucial reproductive adaptations animals needed to make in order to live on land?
One adaptation is the amniotic egg; a waterproof egg with a shell. It also has an amnion that will protect the embryo from drying out. The other is internal fertilization: when the sperm has to enter directly into the female because the sperm does not survive in the air. Previously animals, like sponges, had to spread their sperm through the water in hopes of fertilization. Both of these adaptions are crucial to life on land and we would not be here without them.

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 birds fertilization internal or external?
All birds fertilize their eggs internally. A male bird has to mate with a female in order for a fertilized egg to be produced.

What are the differences between internal fertilization and external fertilization?
Internal fertilization is where the egg is fertilized inside the body(such as humans) and external fertilaztion is where the an egg is laid and then fertilized. Such as in fishes!
What reptile has internal fertilization?
Since most reptiles have hard shells, it would be impossible to fertilize an egg after it is laid. Therefore most reptiles perform a sort of internal fertilization.
What kind of fertilization is the locust?
Locusts use internal fertilization for reproduction. This is when the male locust actively copulates with the female to produce the fertilized egg.
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

How does an embryo in an amniotic egg get oxygen?
The shell on an amniotic egg is equip with very small pores that allow oxygen to seep slowly into the embryo so that it doesn't suffocate.
How do cephalopods reproduce?
fertilization of the female egg is internal and cephalopods have both female and male reproductive organs so reproduction is internal
