Question
Chapter 38, Problem 10TYU
Summary Introduction
To explain: The response against genetically modified food critics.
Concept introduction: Genetically modified foods have been made by scientist by introducing certain changes in the DNA or genome of crop plants by using genetic engineering. It is very different from breeding because in this instead of getting random genes, scientists put a desired gene directly into the plant’s DNA.

In order to establish the expiration date of perishable food, growth curve data must be collected. 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:
