Expert Solution & Answer

Answer to Problem 1P

Correct answer: The statement is true.

Explanation of Solution

The objects that are 500nm wide are able to detect clearly under the light microscope. However, smaller than this size appears blur due to wave-like nature of light. The DNA double helix is only 2 nm wide. Thus, it is below the limit of resolution of the light microscope. Hence, it is not possible to see the chromosomes in living cells under the light microscope without special stain. Hence, the statement is true.

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: 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 16
