Internal fertilization is like animals having sex....the egg is fertilized on the inside. External is when the egg is fertilized on the outside (like when frogs lay eggs and they need to be fertilized before they can hatch).
Hen eggs are fertilized internally by a male rooster before being laid by the hen, while starfish eggs are typically released into the water and fertilized externally by sperm released by male starfish. Additionally, hen eggs have a hard shell for protection, while starfish eggs are usually small and jelly-like.
Embryonated egg culture is a method used to cultivate viruses by injecting the virus into a developing embryo. The virus can then multiply in the cells of the embryo, allowing for the production of large quantities of the virus for study or vaccine production. This method is commonly used for viruses such as influenza.
Chickens typically start laying fertilized eggs when they are around 5-6 months old, depending on the breed. However, the quality and consistency of egg production may vary between individual chickens.
No, not all chicken eggs are fertilized. Most mass-produced eggs from battery farm operations are not fertilized, as the hens live their whole lives without seeing a rooster. Roosters must mate with the female chickens in order for the hens to produce fertilized eggs. No rooster, no fertilization. Hens are able to produce fertilized eggs for 1-2 weeks from one conjugal encounter with a rooster, but it takes a few days for the rooster's sperm to begin fertilizing her eggs.
Hens will lay eggs regularly without the necessity for fertilization. The only difference between a fertilized and unfertilized egg is that a fertilized egg has the potential to hatch and become a chick, while the other does not. Several prominent institutions have conducted studies comparing the nutritional values of fertilized eggs to unfertilized eggs. The result was that both kinds of eggs are nutritionally the same.
Yes, of course they are! In fact, ALL the eggs you buy in the grocery store are unfertilized. The only difference between fertilized and non-fertilized eggs is the tiny drop of sperm. It adds an infinitesimal amount of protein. BIG on the downside: fertilized eggs go bad quicker.
No.
Yes - the only difference in a very few cells amongst many, many millions.
The difference is so minute that there is essentially no difference. The "rumor" that fertilized eggs are lower in cholesterol than unfertilized eggs is untrue.

There is no nutritional difference between a fertilized and an unfertilized egg. People prefer to eat unfertilized commercial layer eggs, so they don't feel like they are eating the next generation. Also a fertilized egg does not have as long of a shelf life as the unfertilized one does.
Depends on the animal, but in general male produces sperm, female produces eggs, and MAY hold fertilized eggs until they grow (but not always)
It is important to know what is being consumed. When a person eats eggs, they are suppose to eat unfertilized eggs, as a fertilized egg with have some formation of an animal in it.No. Most eggs sold today are from large egg producing facilities and there are no interactions between hens and roosters. Most of the egg producing hens have never and never will see a rooster. The only time you may get fertilized eggs is if you buy from a local farm and unless you incubate the eggs you would never know you are eating a fertile egg. There is no discernible difference between a fertile and non fertile fresh egg.Yes, there is really no difference nutritionally between fertile and non-fertile eggs. Unless the egg has been incubated for several days there is no visual difference either. Farm fresh eggs are more often fertile than not. Store bought factory produced eggs are never fertile.The chicken eggs we eat are unfertilized. Actually some are fertilized. It depends on what type of egg you get. But after they have been refrigerated they will not hatch.
Identical twins come from the same fertilized egg; fraternal twins come from 2 fertilized eggs.
If you have fertilized eggs you will not have periods, you are pregnant! not much
