Does the development of the amniotic egg make early reptiles less dependent on water?
Yes! :) hope it helped
Does development of the atomic egg made early reptiles less dependent on water?
There is no such thing as an 'Atomic' egg.However, the amniotes are a group of four-footed animals with backbones or spinal columns that have a terrestrially adapted egg. Amniote embryos, whether laid as eggs or carried by the female, are protected and aided by several extensive membranes, including an amniotic sac that surrounds the fetus. The membrains protect the egg form drying out on land.There is such thing as an Amniotic egg tho its in my science book :P
Similarities in the development of this early stage of life such as the presence of an amniotic sac show organisms are related?
Embryo
Why is the amniotic egg considred an important evolutionary breakthrough?
It shows how life forms are all very similar in early development stages.
How did the evolution of an amniotic egg help reptiles?
The amniotic egg allowed early reptiles to move away from waterside habitats and colonize dry regions. It allowed reproduction on land by preventing the embryo from drying out, so eggs could be laid away from the water.
Are mammals evolved from early reptiles?
no they did not they where alive with the reptiles
Did fish evolve from early reptiles?
no, the reptiles evolved from fish
Is a amniotic egg a characteristic of reptiles?
The amnion is a semi-permeable membrane that retains moisture within the egg, thus preventing it from drying out, but permits the exchange of gasses, thus enabling the developing animal to breathe. With its evolution, it became possible for the amniotes (such as reptiles) to lay their eggs away from water and still successfully reproduce, as all embryos need to develop in a moisture-rich environment. Amphibian eggs lack the amnion, just as all the early tetrapod eggs did, and they could never lay their eggs in a dry environment, as their embryos would die long before they fully developed.
Does a reptile have a cerebellum?
It's possible that early reptiles did not, but modern reptiles certainly do.
Did amphibians evolve from early reptiles?
no
How early will the amniotic sac show up on an ultrasound?
My doc just told me usually 8 weeks
What is an organism in the early stages of development?
An organism in the early stages of its development is an embryo.
