The mystery food sample tested positive for lipids using the Sudan red indicator.
Nicole ate salad dressing.
Salad dressing contains fat, a lipid.
Nicole is probably guilty.
The right choice for your question is A. A dog has three alleles for a certain fur color.
<span>Once collected, lymph ultimately drains into venous circulation.
<u />Lymph goes from terminal lymphatic ducts into venous circulation through the subclavian veins.
Lymph is not filtered or detoxicated yet at this point, and it doesn't go to arterial circulation because that would just distribute it all over the body, instead of just the heart.

The phospholipid bilayer has two hydrophilic surfaces: the extracellular and the intracellular surfaces. These two layers sandwiches a major layer of lipids or fat. Because of this nature of the lipid bilayer, water-soluble or <em>hydrophilic</em> hormones cannot enter the cell membrane. They have to rely on the mechanisms of receptors.
One can find transmembrane proteins embedded across the whole length of the lipid bilayer. One of the functions of these proteins is to serve as the link for hormones such as the ones given above. When the water-soluble hormones attach to one of these receptors, the receptor will be activated and send down a signal to the intracellular environment; these signals will then travel down towards their target site and eventually activate whatever it is the hormone was made for. One example of these transmembrane proteins are <em>G-coupled proteins; </em>examples of signals that cascade down the cell are cylic AMP and cyclic GMP.
