Question: According to Mendelian inheritance, variations in an organism's phenotype (observable physical and behavioral characteristics) are due in part to variations in its genotype (particular set of genes). Each gene specifies a particular trait with different sequence of a gene (alleles) giving rise to different phenotypes. Most eukaryotic organisms (such as the pea plants Mendel worked on) have two alleles for each trait, one inherited from each parent.:20
Is there an answer to this question: What sort of characteristics are described by an organism's phenotype?

Answer: observable physical and behavioral characteristics


Question: To unambiguously specify the date, dual dating or Old Style (O.S.) and New Style (N.S.) are sometimes used with dates. Dual dating uses two consecutive years because of differences in the starting date of the year, or includes both the Julian and Gregorian dates. Old Style and New Style (N.S.) indicate either whether the start of the Julian year has been adjusted to start on 1 January (N.S.) even though documents written at the time use a different start of year (O.S.), or whether a date conforms to the Julian calendar (O.S.) rather than the Gregorian (N.S.).
Is there an answer to this question: What is the Old Style date mean?

Answer: Julian calendar


Question: Early Islamic philosophy and Islamic metaphysics, imbued as it is with Islamic theology, distinguishes more clearly than Aristotelianism between essence and existence. Whereas existence is the domain of the contingent and the accidental, essence endures within a being beyond the accidental. The philosophy of Ibn Sīnā, particularly that part relating to metaphysics, owes much to al-Farabi. The search for a definitive Islamic philosophy separate from Occasionalism can be seen in what is left of his work.
Is there an answer to this question: What does Muslim philosophy more clearly explain than Aristotelianism?

Answer: unanswerable


Question: An FBI special agent is issued a Glock Model 22 pistol or a Glock 23 in .40 S&W caliber. If they fail their first qualification, they are issued either a Glock 17 or Glock 19, to aid in their next qualification. In May 1997, the FBI officially adopted the Glock .40 S&W pistol for general agent use and first issued it to New Agent Class 98-1 in October 1997. At present, the Model 23 "FG&R" (finger groove and rail) is the issue sidearm. New agents are issued firearms, on which they must qualify, on successful completion of their training at the FBI Academy. The Glock 26 in 9×19mm Parabellum, and Glock Models 23 and 27 in .40 S&W caliber are authorized as secondary weapons. Special agents are authorized to purchase and qualify with the Glock Model 21 in .45 ACP. Special agents of the FBI HRT (Hostage Rescue Team), and regional SWAT teams are issued the Springfield Professional Model 1911A1 .45 ACP pistol (see FBI Special Weapons and Tactics Teams).
Is there an answer to this question: What are FBI special agents issued if they fail their first qualification?

Answer:
Glock 17 or Glock 19
