Chapter 1, Problem 1RQ
Why is life difficult to define?
Expert Solution & Answer
Summary Introduction
To determine: The reason for the difficulty in defining life.
Introduction: Life is a characteristic that differentiates living and non-living. All the common characteristics that lie in ancestors, past and present are a part of the concept of life.
Explanation of Solution
The general features of life include chemical uniqueness, reproduction, complexity and hierarchical organization, possession of genetic program, metabolism, development, movement, and environmental interactions. These factors differentiate the living and non-living characteristics and define life. All the characters still have some exceptions, which makes it difficult to define. Example-Body movement is the characteristics of a living thing, but plants do not move, and still, they are living.

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:

It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth. Did a patient relationship with the transfusing hospital exist?arrow_forward
