Chapter 1 Introduction to Microbes and Their Building Blocks (McGraw Hill)-
Homework
1. Which of the following choices is a correct way to denote the binomial name of a
microorganism?
Multiple Choice
• Staphylococcus Aureus (correct answer)
Explanation
The binomial, or scientific name, of a microorganism must be typed in italics or underlined if
handwritten. In addition, the first letter of the generic part of the name must be capitalized while the first
letter of the species name is lowercase.
2. Which of the following is a macromolecule that assembles into bilayers?
Multiple Choice
• Phospholipid (correct answer)
• Nucleic acid
• Carbohydrate
• Protein
3. Please watch the video below, and then use what you have learned from the chapter to answer the
questions, demonstrating your understanding of biofilms.
1.) What is a biofilm?
• Free-floating bacteria that move through the blood to other sites
• A group of bacteria that accumulate in layers and secrete protective extracellular
material
• A layer of sugars that persist even after bacteria have been killed by antibiotics
• A bacterial cell that secretes an extensive network of fibers around its cell wall Incorrect
