why does the yellow (yolk)remain in center? not at top or at bottom?

Answer 1

Favorite Answer

An egg yolk is the part of an egg which serves as the food source for the developing embryo inside. The yolk together with the germinal disc is a single cell. The egg yolk is suspended in the egg white (known more formally as albumen or ovalbumin) by one or two spiral bands of tissue called the chalazae.

Answer 2

there is a thin string like line holding the yolk in place. the yolk has a thin costing around it, to stop it mixing with the egg white and the inside of the shell is coated with a thin rubbery interior cover. the yolk is suspended between these.

sometimes when u crack an egg, u can see a small string in there.

Answer 3

The yolk is held in place by a thick white membrane called a chilaza that you can see when you crack an egg...Thank you 7th grade Home Ec!

Answer 4

My guess is that the yolk is less dense than the white so it is not able to displace/replace the egg white in any direction and so stays in the centre. It probably has a skin too. Beatsa me.

Answer 5

You know that little white thing that is partly on the yolk and the clear part...that is a membrane that connects the two, keeping it in the middle

Answer 6

Because when the egg is an embryo,the egg white's function is to protect the yolk(embryo) in the middle against all hard knocks or whatever,so it is in the middle.

Answer 7

Its known as specific gravity. the yoke is suspended-untill ya scramble it. The yoke is on you!

Answer 10
