A mature female may have its body cavity full of black and white eggs. the black portion of the egg contains the living embryo. the white portion is yolk, containg stored food. when placed in water the eggs will float with the light side down. what is the advantage of this?

- synthesis of yolk proteins carried out by other non-germ cells: is panoistic ovaries, fat body elsewhere in the organism is producing proteins, carried towards and deposited in the oocyte

- labelled precursor with ferretin, when looked at under microscope it shows up black

- electrophoresis, proteins migrate along gel in an electric current, proteins in body fluid of organism were identical to the proteins within the yolk of the oocyte

- immunological methods using antibodies, more sensitive way of detecting yolk-protein-like proteins in the body fluid

These are the advantages:

synthesis of yolk proteins carried out by other non-germ cells: is panoistic ovaries,
fat body elsewhere in the organism is producing proteins, carried towards and deposited in the oocyte.
labelled prototype with ferritin, when looked at under microscope it shows up black.
electrophoresis, proteins migrate along with gel in an electric current, proteins in the body fluid of organism were identical to the proteins within the yolk of the oocyte.
immunological methods using antibodies, a more sensitive way of seeing yolk-protein-like proteins in the body fluid.

What is the main protein in the yolk?

The major proteins found in egg yolk include low-density lipoprotein (LDL), which constitutes 65%, high-density lipoprotein (HDL), phosvitin, and livetin.

These proteins live in a homogeneously emulsified fluid. Egg white is made up of some 40 different types of proteins.

Thus, these are the advantages.
