it is composed of three layers:an outer cuticular layer,intermediate fibrous layer,and inner mucous layer. the cuticular layer is continued with the skin of external acoustic meaus; the fibrous layer lies b/w cuticular and mucous layer; the mucous layer is continued with the mucous membrane of tympanic membrane.
Two phospholipid layers? I think.
2 layers of lipids.

There are 2, surrounding a water layer.
There are no bone in the eardrum (tympanic membrane). The three auditory ossicles (little bones) are located in the middle ear. They are the only bones in the ear.
There are two layers of phospholipids in the plasma membrane, with each layer composed of phospholipid molecules arranged in a bilayer structure. This bilayer provides the membrane with its characteristic flexibility and semi-permeability.
I think you are referring to the cristae. These are the folded parts of the inner membrane. The purpose is to increase surface area of the inner membrane against the matrix. The membrane is the site of the energy transfer in the mitochondria, so having more surface area is a plus.
The composition of the example sentnce must use the word comprise.How many ingredients does this recipe comprise?
The answer you're looking for is probably two, because a membrane consists of two layers of phospholipids, but it really depends on how the word "layer" is defined in this context.
A cell membrane consists of two layers of phospholipids, making it a double-layered structure. This double layer is known as a lipid bilayer.
