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.
What does the porous shell of the amniotic egg allow to happen?
Oxygen can get to the embryo. Of course, it´s also the reason sea turtles lay their eggs on land, it works both ways.
Why is it important that an amniotic egg shell is semi permeable?
The semi-permeable nature of an amniotic egg shell allows gases, such as oxygen and carbon dioxide, to pass through, enabling the exchange of respiratory gases for the developing embryo. This is essential for the embryo's survival as it allows for proper respiration. Additionally, the semi-permeability helps regulate the water content within the egg to maintain the optimal environment for embryonic development.
What type of egg is composed of a protective shell and membranes that surround the developing embryo?
A type of egg is composed of a protective shell and membranes that surround the developing embryo is an egg
What keeps embryo from drying out?
The amniotic fluid surrounding the embryo provides a protective, hydrated environment that prevents it from drying out. This fluid helps to cushion the embryo and maintain a consistent level of moisture, essential for its development. Additionally, the amniotic sac acts as a barrier to prevent dehydration.
Do lobsters have amniotic eggs?
No. An amniotic egg is a bird or reptile egg, with a shell. Only vertebrates can have amniotic eggs. ^^ By extention, mammals also have amniotic eggs, but they're reduced in placental mammals (live birth). Platypi and echidnas still lay amniotic eggs though.
How is an amniotic egg important adaptation for reptiles?
The amniotic egg allows reptiles to reproduce on land, away from water.
What are the four membranes in an amniotic egg.?
The amniotic egg has seven different parts that play different functions. The seven parts include the shell, albumen, chorion, yolk, allantois, ammunion and embryo.
How are the pores of egg shell usefull to the embryo inside?
It gives the embryo oxygen it needs to survive in the egg.
Why do gases travel across the shell of a reptile egg?
The embryo inside the egg is carrying out cellular respiration. In order for it to do that oxygen must be able to enter the egg and carbon dioxide must be able to leave.
What might happen to a reptile egg if part of its shell were removed?
Removing part of the shell of a reptile egg can expose the embryo to potential damage or infection due to loss of protection. It can also lead to dehydration of the embryo, affecting its development and possibly leading to death. The egg may also be more vulnerable to physical damage or predation.
Do most snakes lay amniotic eggs?
Yes, most snakes are oviparous, meaning they lay amniotic eggs. These eggs are enclosed within a shell that allows for gas exchange and protects the developing embryo.
