Charles is an engineer who is evaluating a prototype of an artificial heart. He should notice the prototype missing is : a structure that would divide the hollow heart into chambers to separate oxygenated blood from deoxygenated blood.
It depends on the placing of the mutation. If the mutation is in a coding area then it may effect function of the amylase by preventing proper folding of the protein or the formation of bonds that hold the protein together, for example a mutation in a cysteine residue may inhibit the formation of a disulphides bond.
It may have to do with more olden stereotypes, where women were seen to be caretakers of the family, while the male went out to work and earn for them. Many jobs back then were dependent on strength, so as long as men fulfilled their role of earning money (through labor) their looks were seen as little importance. Let me elaborate. If a man could care for his family, he was seen as admirable, or at least acceptable to society. If he couldn't earn, then he was deemed worthless. So a man's honor depended on how his strength was. In this sense, looks didn't really contribute to a man's place in society. Women, on the other hand, were the face of the family. Men would show them off to friends, so if women weren't decently attractive, then it wouldn't be very good for the male. Other than housework, the woman's job is to literally sit still and look pretty; thus the reason behind corsets, bonnets, petticoats and so on. You won't see society asking men to wear such complicated things, because their main job is to work. It would be unsuitable for a blacksmith to be wearing tight suits while hammering, no? I hope this gave you some general insight.
This is indicative of classical conditioning as studied by Pavlov. There is an unconditioned stimuli, in this case, Kendra’s nausea wherein nausea is not often associated with alcohol. The conditioned stimuli here is the smell of liquor which does not normally associate with nausea in other humans. In this case, Kendra’s nausea is now associated with the smell of liquor; yet another possible conditioned stimuli such as the sight of bottle was not associated.<span> </span>
