This questiоn hаs fоur pаrts, A - D. Indicаte where the fоllowing pharmaceuticals would be found physiologically: the blood (aqueous), tissues (less aqueous), or in lipids (least aqueous, hydrophobic). Click to Show Image Description The skeletal chemical structure shows three fused rings across the top, with two outer six-membered rings containing alternating double bonds and a larger central ring. A three-carbon chain extends downward from the central ring and ends at an N atom. The N atom is bonded to two one-carbon groups. [AnswerA] Click to Show Image Description The skeletal chemical structure shows a central six-carbon benzene ring with four substituents. The upper-left substituent is a C(=O)OH group. The lower-left substituent is a sulfur-containing group shown as S bonded to two O atoms and an H₂N group. Cl is bonded to the lower-right side of the benzene ring. An HN group is bonded to the upper-right side of the ring and connects through CH₂ to a five-membered ring containing one O atom and two double bonds. [AnswerB] Click to Show Image Description The skeletal chemical structure shows a fused ring system on the left connected through a sulfur-containing linker to a six-membered ring on the right. The left fused system includes a six-carbon ring bonded to a five-membered ring containing two N atoms, one shown as N-H. A methoxy group extends from the left side of the fused ring. The sulfur linker is bonded to O with a double bond and connects to the right-hand ring through a one-carbon chain. The right-hand ring contains one N atom, two double bonds, two one-carbon branches, and one methoxy group. [AnswerC] Click to Show Image Description The skeletal chemical structure shows a fused two-ring system on the left, with an upper benzene ring fused to a lower six-membered ring. An HN group bonded to CH₃ extends from the left side of the lower ring on a dashed wedge bond. A solid wedge bond extends from the right side of the lower ring to a benzene ring on the right. The right benzene ring has two Cl substituents, one extending to the right and one extending downward. [AnswerD] The compounds shown above (and the same are provided below) include: an antidepressant (must cross blood-brain barrier), a compound to release fluid buildup in kidneys, a muscle relaxant, and a stomach acid inhibitor (PPI). Which one is which?

Identify the cоntext аnd significаnce оf this quоtаtion from Gulliver's Travels (4-6 good sentences): I remember my master having once made an appointment with a friend and his family to come to his house, upon some affair of importance: on the day fixed, the mistress and her two children came very late; she made two excuses, first for her husband, who, as she said, happened that very morning to shnuwnh. The word is strongly expressive in their language, but not easily rendered into English; it signifies, “to retire to his first mother.” Her excuse for not coming sooner, was, that her husband dying late in the morning, she was a good while consulting her servants about a convenient place where his body should be laid; and I observed, she behaved herself at our house as cheerfully as the rest.
