Summary Introduction
To determine: The role of vitamin D and folic acid nutrition in explaining the variation in human skin pigmentation.
Concept introduction:
Human skin color ranges in variety from the darkest brown to the lightest hues. An individual’s skin pigmentation is the result of genetics. Human skin pigmentation has evolved as a compromise between the conflicting physiological demands of protection against the harmful effects of ultraviolet.

Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a load of x50,000 bacteria/gram is considered unsafe. Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured: Time (days) MicroYo colony count# 1 1 4 1 12 2 16 20 4 7 What day should you recommend expiring the yogurt (the last possible date before the microbial load is unsafe). 12 4 20 16arrow_forward
