You Have Identified the Causative Organism of the Outbreak as E

question 53

Multiple Choice

You have identified the causative organism of the outbreak as E. coli. In an effort to characterize the strain of the organism involved, you do different tests. The results are as follows:
Gram stain-Gram-negative rods; Oxidase test-negative; Lactose fermentation-positive; Serological testing-O157:H7; Colony morphology-smooth, creamy colonies; RFLPs-E. coli O157:H7; Antibiogram-resistant to ampicillin.
Which test(s) confirm the identity of the organism at the strain level?

• A) Gram stain AND antibiogram
• B) Serological testing AND colony morphology
• C) RFLPs AND serological testing
• D) Oxidase test AND RFLPs
• E) Lactose fermentation AND oxidase test

Grasp the significance of empirical data, such as population sizes and trait distributions, in studying evolution.

Relate environmental changes and challenges to the evolution of reproductive strategies.

Understand the fiduciary responsibilities of shareholders within a corporation.

Identify and explain the concepts of shareholder oppression mechanisms such as squeezing out noncontrolling shareholders.

Definitions:

Butane Conformers

Different spatial arrangements of atoms in butane that result from rotation around single bonds, affecting the molecule's energy.

Energy Minima

Points in a potential energy surface that represent stable states of a system, where any small displacement of particles leads to an increase in potential energy.

Dihedral Angle

The angle between two planes defined by four atoms, often used to describe the orientation of parts of a molecule relative to each other.

Steric Strain

A form of strain in molecules resulting from repulsive interactions when atoms are forced too close to one another, influencing molecule stability and reactivity.
