Microbiology and Atomic Structure Quiz (Chapter 1)

What are the different groups of microbes? Describe their similarities and differences.

• Bacteria, Archaea, Fungi, Viruses, and Algae; all are prokaryotic.

• Bacteria, Archaea, Fungi, Viruses, and Protozoa; Bacteria and Archaea are prokaryotic, while Fungi and Protozoa are eukaryotic.

• Bacteria, Archaea, Fungi, Viruses, and Protozoa; all are eukaryotic.

• Bacteria, Archaea, Fungi, Viruses, and Algae; all are eukaryotic.

What is spontaneous generation? How was it disproved?

• The theory that life arises from non-living matter; disproved by Robert Koch's postulates.

• The theory that life arises from non-living matter; disproved by Louis Pasteur's swan-neck flask experiment.

• The theory that life arises from living matter; disproved by Antony Van Leeuwenhoek's microscope observations.

• The theory that life arises from living matter; disproved by Louis Pasteur's germ theory.

Describe the contributions to microbiology made by Antony Van Leeuwenhoek, Louis Pasteur, Robert Koch.

• Leeuwenhoek discovered bacteria; Pasteur developed pasteurization; Koch identified the cause of tuberculosis.

• Leeuwenhoek developed pasteurization; Pasteur discovered bacteria; Koch identified the cause of tuberculosis.

• Leeuwenhoek identified the cause of tuberculosis; Pasteur discovered bacteria; Koch developed pasteurization.

• Leeuwenhoek discovered viruses; Pasteur developed vaccines; Koch discovered bacteria.

What is an atom? Describe its parts.

• The smallest unit of matter; consists of protons, neutrons, and electrons.

• The smallest unit of life; consists of cells, tissues, and organs.

• The smallest unit of energy; consists of photons, quarks, and leptons.

• The smallest unit of a compound; consists of molecules, ions, and bonds.

What is matter?

• Anything that has energy and can do work.

• Anything that has mass and occupies space.

• Anything that can be seen and touched.

• Anything that is living and can reproduce.

Define atomic number and atomic mass.

• Atomic number is the number of protons; atomic mass is the sum of protons and electrons.

• Atomic number is the number of neutrons; atomic mass is the sum of protons and neutrons.

• Atomic number is the number of protons; atomic mass is the sum of protons and neutrons.

• Atomic number is the number of electrons; atomic mass is the sum of electrons and neutrons.

What are the 4 elements that make up 96% of the mass of an organism?

• Carbon, Hydrogen, Oxygen, Nitrogen

• Carbon, Helium, Oxygen, Nitrogen

• Calcium, Hydrogen, Oxygen, Nitrogen

• Carbon, Hydrogen, Oxygen, Phosphorus

What is an isotope?

• Atoms of the same element with different numbers of protons.

• Atoms of different elements with the same number of neutrons.

• Atoms of the same element with different numbers of neutrons.

• Atoms of different elements with the same number of protons.

What are valence electrons?

• Electrons in the innermost shell of an atom.

• Electrons that are shared between atoms in a covalent bond.

• Electrons in the outermost shell of an atom.

• Electrons that are transferred in an ionic bond.

What are the three major chemical bonds? Describe how each works? Which is strongest? weakest?

• Ionic, covalent, hydrogen; covalent is strongest, hydrogen is weakest.

• Ionic, covalent, metallic; ionic is strongest, metallic is weakest.

• Covalent, hydrogen, metallic; metallic is strongest, hydrogen is weakest.

• Ionic, hydrogen, metallic; ionic is strongest, hydrogen is weakest.
