To propose a hypothesis: To compare the structures of tobacco mosaic virus and influenza virus. Introduction: Virus is a distinctive class of microscopic organisms that are infectious in nature. They are typical parasites that can replicate only inside a living host like bacteria, animals, plants, etc. The viral genome is made of nucleic acid , DNA or RNA, which can be either single or double stranded, circular or linear. The nucleic acid is enclosed within a protective protein coat known as capsid. Capsomere is structurally made of individual protein subunits that self-assemble to form a capsid. Virus can infect both plants (e.g. tobacco mosaic virus) and animals (e.g. influenza virus). In some virus the virus capsid is surrounded by a structure called as envelope. This viral envelope is made of lipids and proteins and helps in viral attachment and transfer of genetic material to host.

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
