The calcium that makes the egg shell makes it hard.
Yes. Bird eggs are similar in structure to reptile eggs with the main difference being that bird eggs have a hard shell while reptiles eggs have a softer, leathery shell.
no.
are found on land, so they do not have a moist environment to keep them from drying out, and have a leather shell, instead of a hard shell. hard shells are better at keeping water and liquids in, while leather shells are not
No snake does unless scientist fond another specie is found .
Reptiles, such as turtles, snakes, and lizards, produce eggs with a leathery shell. The leathery shell is flexible and allows the eggs to absorb moisture and exchange gases with the environment. Unlike reptiles, birds and some other groups of vertebrates produce eggs with a hard, calcified shell.
All eggs that have a hard or semi hard shell are fertilized before being laid.
it is because egg shell contains calcium and this what makes it white
Yes, it does DEFIANTLY! cockroaches lay there eggs with hard shells, as it easier for cockroaches to reproduce.. .. HOPE IT HELPS! :) :) :) :)
It depends on how fresh they are. Eggs that are very recently laid will often have the white stick to the shell a bit.
NO- the vast majority of the commercial eggs are infertile- the hen never sees a rooster. Fertilization of the egg happend BEFORE the shell membranes and shell are added. Fertilization is not needed to form a shell.
All bird eggs are hard, there is no choice. Ones without a proper shell are defective and usually won't hatch.
Fish eggs, commonly referred to as roe, typically have a jelly-like texture. They are generally not enclosed in a hard shell like bird eggs; instead, they are often surrounded by a soft, gelatinous membrane. The texture can vary slightly depending on the species of fish, but the overall characteristic is more akin to a jelly shell.
