    If you're a fat molecule forming the inner layer of a cell membrane,your head will face toward ?

    Fat molecules do not have heads. Can you rephrase the question?

    The best way I can rephrase it is
    If you're a fat molecule forming the inner layer of a cell membrane, which way would it face?

    There is no front or back or "face" to a fat molecule. What exactly are you looking for?

    Have you tried to GOOGLE that phrase? Many instructors put their language in terms that can GOOGLE.

    Could he/she maybe mean something about the nucleus and its specific location?

    Pretty vague to me.

    The only way I can tell you what I looking for is to give you the answer choice that I have.
    A. the watery environment outside a cell.
    B. the watery environment inside the cell.
    C. either the inside or the outside of the cell
    D. the protein pump in the cell

    I would have to go with

    A

    Adipose tissue, fat cells, float.

    D. Protein PUMP?

    However, C covers the first two.

    Has this been brought up again as Tammy also wants the answer?

    Anyway I think the OP was referring to the polar 'head' of a phospholipid.
    Long carbon chains are hydrophobic whereas the phospho-head is hydrophilic. In a biological membrane this will cause it to face towards the cytosol. It will also cause it to face the outside of the cell which is also aquous, the hydrophobic tails tuck up together forming what is known as the phospholipid bi-layer.

    Lipid bilayer - Wikipedia, the free encyclopedia

    Hope this helps anyone interested in the answer to this question.
