Summary Introduction

To determine:

The characteristics of viruses that could be used to characterize them as life forms.

Introduction:

Viruses are defined as the biological agent that is able to reproduce inside the cell of living host. After infection, the host cell produces thousands of identical copies of viruses. They can infect all living organisms such as animals, plants, microorganisms, and humans.

Explanation of Solution

The virus is defined as non-cellular organisms which is composed of genetic material such as either DNA or RNA and protein. They have the ability to invade in living cells. Viruses are considered as both living and non-living organisms. The general characteristics of viruses are as follows:

(a) Viruses are enclosed within a protective envelope which is made of lipoprotein.

(b) Viruses are composed of viral protein coat which is called as capsid and capsid and envelope are responsible for infection in the host.

(c) They are composed of spikes that help in the attachment of viruses with the host cell.

(d) They have to ability to reproduce and form multiple copies inside the host cell.

(e) Viruses may contain either DNA or RNA as their genetic material.

(f) Viruses are active and considered as living cells when they are inside their host.

(b)

Explanation of Solution

Viruses are non-cellular parasites that can exist in both living and non-living forms. They do not have the ability to metabolize molecules and respire. They are not composed of cell organelles. Viruses do not have their own replication machinery. They have the ability to crystallize and can also be precipitated. Viruses when in the non-living state do not show growth, development, nutrition, and reproduction.

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
