<span>Fats, oils and cholesterol are all types of lipids.Lipids are biomolecules that consist in long chains of carbons and hydrogen, insolubles in water (becauise they are not polar). Many lipids have in common the functional group corboxilic, COOH. Cholesterol, fats and oils all have carboxlic group. </span>
Pheromones used in reproduction are not likely to be found in organisms that only reproduce asexually.
The chemicals called pheromones are used to communicate between members of the same species and cause the recipient to react physically or behaviorally. Pheromones are a subset of organisms' larger class of chemicals to communicate, known as semiochemicals, from the Greek <em>semeon</em>, meaning signal or mark.
Animals communicate chemically constantly, with pheromones mediating more interactions than any other type of signal. The majority of pheromone research has been conducted on insects, particularly species that are considered pests.
For these, using pheromones that alter their behaviour in various ways might be employed for population control, pest management, or monitoring.

Answer:
Pyrimidines
Uracil = 2,4-dioxy pyrimidine
Thymine = 2,4-dioxy-5-methyl pyrimidine
Cytosine = 2-oxy-4-amino pyrimidine
Orotic acid = 2,4-dioxy-6-carboxy pyrimidine
Polynucleotides
Nucleotides are joined together by 3'-5' phosphodiester bonds to form polynucleotides. Polymerization of ribonucleotides will produce an RNA while polymerization of deoxyribonucleotides leads to DNA.
