Answer:
diverse proteins embedded in a phospholipid bilayer
Explanation:
According to fluid mosaic model the cell membrane is made of bilayer of phospholipid. Many proteins are embedded in this bi layer. Carbohydrate and cholesterol are also found in different forms. Carbohydrate can either be attached to the embedded protein in which case it is called as glycoprotein or it can be connected to the lipid molecule in layer and called as glycolipid.
Proteins can be found in two forms too. They can either be embedded in the layer i.e. they can penetrate single or both layers. These proteins are called as integral proteins. They can also be present on one side of the membrane and not penetrate the lipid bilayer in which case they are called as peripheral proteins.
Answer:
If contain, the colorant stays, if not, it washes.
Explanation:
The ELISA inmmunoassay experiment consists on adding to an antibody a sample with a colorant, if the sample contains an antigen, it will stick to its proper antibody and te colorant will remain. If not, when the laboratory worker washes the sample after adding the sample, the colorant and the sample will be gone because there wasn´t an antigen on the sample that fitthe antibody. In that case, the result will be negative.
