Questions: Take Quiz Question 17 1 pts Skin color in humans is represented in geography by a cline, or clinal pattern. The skin color cline means that no patterns in skin color are visible in any regions of the world. people living at high altitudes will have a lighter skin color than those who live at sea level. all of the people living in one region will share the same skin color, and people living in another region will share a different skin color. a certain skin color may be more common in one region than another, but the variation is gradual and continuous. Question 18 1 pts Several groups of people, including the Chukchi of Eastern Siberia and Inuit of Alaska, Canada, and Greenland, have darker skin than other people living at similar latitudes. This is due to the high folate content of the diets of these groups. the low folate content of the diets of these groups. the high Vitamin D content of the diets of these groups. the low Vitamin D content of the diets of these groups. Question 19 1 pts The pressure on members of ethnic and immigrant minority groups to abandon their native customs, traditions, languages, and identities quickly and adopt those of mainstream society is the pressure of assimilation consumption amalgamation multiculturalism

Sure, let's address the questions one by one.

Question 17: The answer is D: a certain skin color may be more common in one region than another, but the variation is gradual and continuous.

Explanation:

• A: This is incorrect because there are visible patterns in skin color across different regions of the world.
• B: This is incorrect because skin color is more influenced by latitude and UV radiation exposure rather than altitude.
• C: This is incorrect because it suggests a sharp boundary between regions, which is not the case. Skin color variation is gradual.
• D: This is correct because a cline refers to a gradual change in a trait (in this case, skin color) over a geographical area. Skin color varies gradually and continuously, with certain colors being more common in specific regions due to historical exposure to UV radiation.

Question 18: The answer is C: the high Vitamin D content of the diets of these groups.

Explanation:

• A: This is incorrect because folate content in the diet does not directly influence skin color.
• B: This is incorrect for the same reason as A.
• C: This is correct because the Chukchi and Inuit have diets rich in Vitamin D (from sources like fish and marine mammals), which reduces the need for lighter skin to synthesize Vitamin D from sunlight. This allows them to maintain darker skin despite living in high latitudes with low UV radiation.
• D: This is incorrect because a low Vitamin D content would typically necessitate lighter skin to facilitate Vitamin D synthesis from limited sunlight.

Question 19: The answer is A: assimilation.

Explanation:

• A: This is correct because assimilation refers to the process by which individuals or groups adopt the culture and norms of another group, often the dominant society, sometimes at the expense of their original cultural identity.
• B: This is incorrect because consumption refers to the use of goods and services.
• C: This is incorrect because amalgamation refers to the blending of different cultures or groups into a new, unified culture.
• D: This is incorrect because multiculturalism refers to the coexistence of diverse cultures, where cultural differences are accepted and valued.
