10. What is the opportunity cost in daffodils to go from 0 tulips to 300 tulips? How does this opportunity cost compare with the opportunity cost of going from 600 tulips
to 900 tulips?

As the decrease in the tulip's quantity in the both cases is the same, hence the opportunity cost will also be the same required that the marginal cost remains constant.

Explanation:

Opportunity cost is the value lost in opting to alternative option. This means that if an ice cream costs me $10 then the opportunity cost of eating an ice cream would be $10 because I haven't enjoyed an alternative of an ice cream which would be worth $10. Likewise, if I am deciding to attend a party but I have previously purchased cinema tickets worth $50 then the opportunity cost of attending the party would be $50 and opportunity cost of watching movie would be the loss of entertainment at the party.

The opportunity cost of producing 0-300 tulips is $5 per tulip then it is more likely that the cost of producing 600-900 tulips will also be $5 per tulip.

Thus the opportunity cost here for each case will be:

Case1 0-300 Tulips: 300 Tulips * $5 per Unit = $1500

Case2 600-900 Tulips: 300 Tulips * $5 per Unit = $1500

But if the cost of producing first 300 units of tulips are different from the third 300 units of tulip then there will be of course a difference in opportunity cost.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
