The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound containing no nitrogen exhibits strong, broad absorption across the 2500-3300 $cm^{-1}$ region, accompanied by 2200 (w) and 1715 (s) $cm^{-1}$ bands. Relative absorption intensity: (s)=strong, (m)=medium, (w)=weak. What functional class(es) does the compound belong to? List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 $cm^{-1}$. The functional class(es) of this compound is(are) ________ (Enter letters from the table below, in any order, with no spaces or commas.) a. alkane (List only if no other functional class applies.) b. alkene c. terminal alkyne d. internal alkyne e. arene f. alcohol g. ether h. amine i. aldehyde or ketone j. carboxylic acid k. ester l. nitrile

Which of the following statements is an accurate description of Mendel's Law of Segregation? The segregation of alleles of one gene is independent segregation of the alleles for other genes. Dominant traits segregate with higher frequency in the generation, which is why the offspring exhibit the % ratio. During gamete formation, the dominant alleles segregate frequency than the recessive alleles, which is why this is observed. Dominant gametes are more likely to segregate together cross of a heterozygote than in a cross-fertilization different heterozygotes. The inheritance of one dominant allele means that alleles are more likely to segregate in a single gamete. During gamete formation, two alleles for a trait will equal probability into the gametes.
