(5) Which of the 7 characteristics of life does the nervous system and endocrine system produce? What role do they play in negative feedback loops? (6) Skin tone is produced by melanin, a dark pigment that protects against UV damage. The more melanin a person has in their skin, the darker their skin tone. Originally, all humans had a high melanin load (dark skin). In some parts of the world mutations spread that caused enzymes that produce melanin to be dysfunctional, resulting in less melanin production and lighter skin. (Extra Credit) a. What are the dangers of UV light? b. What are the dangers of not absorbing enough UV light? C. Given this information, in what kind of climate, or in what part of the world, do you think lighter skin tones would be more adaptive, and where would darker skin tones be more adaptive?

He plunged in among the big spruce trees. The trail was faint. A foot of snow had fallen since the last sled had passed over, and he was glad he was without a sled, traveling light. In fact, he carried nothing but the lunch wrapped in the handkerchief. He was surprised, however, at the cold. It certainly was cold, he concluded, as he rubbed his numbed nose and cheek-bones with his mittened hand. He was a warm- whiskered man, but the hair on his face did not protect the high cheek-bones and the eager nose that thrust itself aggressively into the frosty air.

MONEY MAKES YOU LESS LIKELY TO SAVOR SMALL PLEASURES The notion that money can't buy happiness has, in recent years, been backed up by a lot of psychological research. The wealthy have access to many pleasure-producing goods and experiences, so why are they no happier than the rest of us? Rich individuals, and less-wealthy people with money on their minds, are less likely to slow down and savor the Snickers candy bar. Writing in the journal Psychological Science, a research team led by Jordi Quoidbach reports money "impairs people's ability to savor everyday positive emotions and experiences.” They conclude this negative effect can “undercut other emotional benefits provided by money." In other words, that rich guy undoubtedly enjoys driving his fancy sports car to the beach. But once he meets you there, you're more likely to get a genuine happiness out of the gorgeous sunset. Quoidbach and his colleagues reached this conclusion after conducting this study. The experiment featured 40 volunteers, who participated in a taste-testing study featuring varieties of chocolate. However, only half were exposed to a photograph of money as they were tasting the chocolate. Then the researchers evaluated how much joy the participants showed on their faces as they tasted the chocolate. They also found that those had been exposed to the photo of cash “spent significantly less time eating the chocolate, and displayed significantly less enjoyment." The scholars' conclusion: When it comes to happiness, money gives with one hand providing access to pleasurable experiences — but “takes away with the other, by undercutting the ability to relish the small delights of daily living." (Tom Jacobs is the author of "Money makes Your Less Likely to Savor Small Pleasures" published on Jun 14, 2017) Writing Directions: Read the passage above and write an essay responding to the ideas it presents.
