Questions: Multiple Cholce Question Which of the following accounts for the differences in skin tone between individuals? Differences in the amount of melanin produced Differences in the type of melanin produced Differences in the number of melanocytes

The answer is the first one: Differences in the amount of melanin produced.

Explanation for each option:

1. Differences in the amount of melanin produced: This is correct. The primary factor that accounts for differences in skin tone between individuals is the amount of melanin produced by melanocytes. Melanin is the pigment responsible for the color of the skin, and variations in its production lead to different skin tones.

2. Differences in the type of melanin produced: This is partially correct but not the primary factor. There are two main types of melanin: eumelanin (which is brown or black) and pheomelanin (which is red or yellow). While the type of melanin can influence skin tone, the amount of melanin produced has a more significant impact on the overall skin color.

3. Differences in the number of melanocytes: This is incorrect. Most individuals have a similar number of melanocytes, regardless of their skin tone. The variation in skin color is more about the activity of these melanocytes in producing melanin rather than their number.

In summary, the primary factor accounting for differences in skin tone is the amount of melanin produced by the melanocytes.
