Fill in the blanks. Compounds that contain a fused ring system are called . These have three 6-membered rings and one 5-membered ring. Some of these compounds are found in biological membranes. are the building blocks for many lipids, and they generally contain an even number of carbon atoms and an unbranched hydrocarbon chain. are formed when a carbohydrate is glycosidically linked to a hydroxyl group of a lipid. Examples include gangliosides and cerebrosides. These are also found in biological membranes. are the storage form of lipids, accumulating in adipose tissue, and they can be metabolic fuel. These compounds have a polar part, made of three ester groups, and a nonpolar fatty acid tall. made of a long-chain amino alcohol joined, either by a glycositic linkage or a phosphodiester linkage, to a fatty acid. These do not contain . They are abundant in the nervous system. When glycerol is esterified to two fatty acids and a phosphoric acid molecule a is formed. These are found in biological membranes.

Answerthis solution will not form a precipitateexplanationsolubility equilbrium:         pbf₂(s)  ⇄ pb²⁺(aq) + 2 f⁻(aq)the solubility product expression is    (we exclude solids from the equilibrium expression).now suppose we have the trial ion product q, which we can define as    then, we can interpret  q as the product of the concentration of the ions that we have and ksp as the product of the ion concentrations that are needed to form a saturated solution.if q > ksp, then that implies that there will be a surplus of ions that exceed the amount that is required to form a saturated solution. a precipitate will then form (the precipitate continually  forms until the surplus ions are removed and q is decreased to ksp's value).if q = ksp, the saturated solution that forms is barely saturated and the precipitate will be minimal.if q < ksp, then the ion concentration will not be enough to form a saturated solution (so no precipitate).using our information, we calculate the trial ion product:     since q = 2.7  × 10⁻⁸ < ksp =  4  ×  10⁻⁸, a precipitate will not form.

The answer is tea due to the main ingredient being a herb that grows from the ground and sugar that grows from a stalk, i hope this : )     p.s.  can i be brainliest?
