Answer:
The models are missing in the question. The models along with the question is provided in the attachment below.
The answer is : Model A represents the Plasma membrane.
Explanation:
According to the question, model A represents the plasma membrane. The reasons are :
(a). In the model A, the bilayers consists of two leaflets of the amphipathic lipid molecules. Here the polar head groups is in contact with the intra cellular or the extra cellular non aqueous phase, where the non polar tails are facing each other constituting the hydrophobic interior of the membrane.
(b). Lipid are not rigid as well as static structure. In the lipid bilayer, the lipid molecule are able to rotate around their axis freely and diffuse laterally with each leaflet.
(c). The plasma membrane acts as the selective plasma membrane.

Is grossly bloody appearance and has a pH of 6
Rationale: Leakage of CSF from the ears or nose may accompany basilar skull fracture. it can be distinguish from other body fluids because the drainage will separate into bloody and yellow concentric rings on dressing material which is also known as halo sign</span>
Answer: DNA contains the nucleotides guanine (G), cytosine (C), adenine (A), and thymine (T). RNA contains the nucleotides guanine (G), cytosine (C), uracil (U), and thymine (T). The difference between the two is that RNA contains uracil (U) rather than adenine (A).
The base pairs in DNA are adenine with thymine and guanine with cytosine. The base pairs in RNA are uracil with thymine and guanine with cytosine.
