Four phospholipids are present in a mixture, with each phospholipid having a different length for its hydrocarbon tails: phosphatidylcholine (pc): composed of c18 lipid tails phosphatidylethanolamine (pe): composed of c16 lipid tails phosphatidylinositol (pi): composed of c12 lipid tails phosphatidylserine (ps): composed of c20 lipid tails if this mixture of phospholipids is resolved on a thin-layer chromatography (tlc) plate, what will be the order of the phospholipids on the plate at the end of the experiment, from closest to the solvent front to closest to the origin? assume that the length of the phospholipid tails is the primary determining factor in the experiment.

In a hypothetical breed of dogs, coat color is controlled by two genes. there are six different coat colors in this breed: black, brown, cream, gray, silver, and tan. consider the following crosses.cross 1: black females from a lineage of all black dogs are crossed with brown males from a lineage of all brown dogs. f1 males and females are all black. when f1 are intercrossed, f2 males and females are black or brown.cross 2: black females from a lineage of all black dogs are crossed with tan males from a lineage where all males are tan and all females are cream. f1 males are black, f1 females are gray. when f1 are intercrossed, f2 males and females are black, brown, gray, or tan.cross 3: silver females from a lineage where all females are silver and all males are gray are crossed with brown males from a lineage of all brown dogs. f1 males and females are all gray. when f1 are intercrossed, f2 males are black, brown, gray, or tan, f2 females are cream, gray, silver, or tan.select the correct statements regarding the mode of inheritance of the coat color genes.a) both genes are x-linked.b) both genes are autosomal.c) one of the genes modifies the expression of the other gene.d) each gene has an additive effect on the intensity of coat color.e) each gene independently specifies three colors.f) one of the genes is autosomal, and the other is x-linked.
