Question 4

Which of the following represents size relationships from smallest to largest?
A)rhinovirus, Ebola virus, Staphylococcus cell, yeast cell, red blood cell, squamous epithelial cell
B)Ebola virus, Rhinovirus, yeast cell, Staphylococcus cell, red blood cell, squamous epithelial cell
C)Ebola virus, yeast cell, Rhinovirus, red blood cell, Staphylococcus cell, squamous epithelial cell
D)rhinovirus, Ebola virus, Staphylococcus cell, red blood cell, yeast cell, squamous epithelial cell

Accepted Answer

Rhinoviruses are among the smallest viruses, followed by the slightly larger Ebola virus. Staphylococcus cells (bacteria) are larger than these viruses. Yeast cells are eukaryotic and larger than bacteria. Red blood cells are larger than yeast cells but smaller than most other human cells, such as squamous epithelial cells, which are among the largest in this list.

Question 6

Which of the three domains includes organisms that would be most likely to survive the environmental conditions that existed on Earth nearly 4 billion years ago?
A)Eukarya
B)Archaea
C)Bacteria

Accepted Answer

Archaea are the oldest known organisms and are believed to have thrived in the extreme environmental conditions that existed on Earth nearly 4 billion years ago. They are known to be extremophiles, meaning they can survive in extreme temperatures, pH levels, and salinity, making them well-suited to the conditions present on early Earth. Bacteria and Eukarya are believed to have evolved later and may not have been adapted to the harsh conditions of early Earth.

Question 7

What unit of measure is most appropriate for expressing the size of bacteria?
A)micrometer
B)nanometer
C)milimeter
D)picometer

Accepted Answer

Bacteria are generally measured in micrometers, as they typically range in size from 0.5 to 5 micrometers. Nanometers are too small and picometers are too large to accurately measure bacteria. Milimeters are too large of a unit for measuring bacteria.

Question 8

Classification and taxonomy provide information and contribute to each of the following endeavors, except
A)identification of unknown species.
B)the study of evolutionary relationships.
C)tracing the origins of bacteria.
D)selection of appropriate antibiotics.
E)enabling communication among scientists regarding the same and different species of microbes.

Accepted Answer

Classification and taxonomy are fundamental in identifying species, understanding evolutionary relationships, tracing origins, and facilitating scientific communication. However, they do not directly contribute to the selection of appropriate antibiotics, which is more related to understanding the specific mechanisms of action and resistance of bacteria rather than their classification or taxonomy.

Question 13

According to current thought regarding the domains of life, which two domains are believed to be the most closely related?
A)Bacteria and Eukarya
B)Archaea and Bacteria
C)Archaea and Eukarya

Accepted Answer

Recently, evidence from molecular studies has suggested that Archaea and Eukarya are more closely related to each other than either is to Bacteria, making C the correct answer.

Question 14

In bacteria such as members of the Bacillus and Clostridium genera, nutrient depletion is likely to result in
A)germination.
B)sporulation.
C)binary fission.
D)plasmolysis.
E)starvation.

Accepted Answer

Nutrient depletion triggers the process of sporulation in bacteria such as Bacillus and Clostridium, leading to the formation of endospores for survival in unfavorable conditions.

Question 15

During the Gram stain, gram _____ cells decolorize when the alcohol is applied.

Accepted Answer

The answer of During the Gram stain, gram _____ cells...

Question 16

Which of the following characteristics of living things is/are not found among viruses?
A)heredity
B)cellular structure
C)ability to evolve
D)presence of nucleic acid
E)All of these characteristics are lacking in viruses.

Accepted Answer

Viruses do not have a cellular structure, as they are acellular particles. They also lack some cellular processes such as metabolism and reproduction outside of a host cell. However, they do possess heredity in the form of genetic material (either DNA or RNA) and the ability to evolve through mutations and natural selection.

Question 17

The enzyme _____, that is found in tears and saliva, can hydrolyze the bonds in the glycan chains of certain bacterial cell walls.

Accepted Answer

The answer of The enzyme _____, that is found in...

Question 18

The process of endospore formation is _____________, while the process of an endospore growing into a vegetative cell is ____________.
A)germination; sporulation
B)reproduction; sporulation
C)germination; reproduction
D)sporulation; germination

Accepted Answer

The process of endospore formation is sporulation, while the process of an endospore growing into a vegetative cell is germination. Therefore, option D is the correct answer. Option A is incorrect because germination is the process of an endospore developing into a vegetative cell, whereas sporulation is the formation of an endospore. Option B is incorrect because endospore formation is not a form of reproduction, and sporulation refers to the process of forming an endospore, not reproduction. Option C is incorrect because germination is the emergence of an endospore into a vegetative cell, which is the opposite of sporulation.

Question 19
