Fish
To make more chickens.
No. But you can get two eggs fertilized at the same time.
Stem cells come from newly fertilized eggs because those eggs divide and evolve into more specialized cells.
No, both contain the same amount of nutrients.
fertilized Neither is more nutritious. Fertilized eggs have a microscopic germinal disk that sits on top of the yolk. That is the only difference. Fertilized eggs are usually fresher than store purchased eggs however and may taste different because of the freshness.
Eggs get fertilized by the cockerel. Sorry, you don't get to choose what gender comes from the fertile egg, neither does the rooster nor the hen.
sharks and more
The number of eggs an animal produces is related its form of fertilization and development because the more eggs there are, the more likely it is for one to be fertilized.
its more easy to give birth in water
Courtship and mating take place in flight. Once the hen is fertilized she lays a clutch of eggs (two or more) and incubates the eggs.
Most frogs and fish abandon their eggs meaning that predators will eat many of the eggs. Therefore for enough eggs to survive they must lay many times more eggs than will be eaten. Hens tend their eggs continuously from when they are laid until they hatch protecting them from predators. Also a hen "invests" more per egg than frogs and fish do, meaning it takes more effort to lay each egg. Note: Hens can lay one egg per day and stop when they have all of them in the nest that they are able to manage. This is why farmers remove the eggs daily to keep the hens laying.
It Depends On The Species Of Frog. Become More Specific and I will answer it.
