Question 1

Robert Koch developed a vaccine that could be used to prevent anthrax.

Accepted Answer

Robert Koch is famous for identifying the bacterium that causes anthrax, Bacillus anthracis, and for formulating Koch's postulates, but he did not develop a vaccine for anthrax. The first anthrax vaccine was developed by Louis Pasteur.

Question 2

Some microorganisms are useful in bioremediation processes that reduce the effects of pollution.

Accepted Answer

Some microorganisms, such as certain types of bacteria and fungi, have the ability to break down or metabolize pollutants in the environment. This process is known as bioremediation and can be used to reduce the effects of pollution in soil, water, and air. Therefore, the statement is true.

Question 7

An Italian physician,__________,challenged the concept of spontaneous generation by demonstrating that maggots do not arise from decaying meat but rather from developing fly eggs.

Accepted Answer

The answer of An Italian physician,__________,challenged the concept of spontaneous...

Question 8

The usefulness of agar in solidifying microbiological growth media is limited because it does not remain solid at temperatures above 28^oC.

Accepted Answer

The statement is incorrect. Agar remains solid up to temperatures of around 85°C, which is well above the optimal growth temperature for many microorganisms. Therefore, it is a useful tool in microbiology for solidifying growth media.

Question 9

Which of the following provides the best explanation for why viruses are not included in the three domain system?

Accepted Answer

Viruses are not considered a cellular life form because they lack the characteristics of living organisms such as metabolism, reproduction, response to stimuli, and growth. Therefore, they do not fit into the three domain system, which classifies cellular organisms based on genetic and biochemical criteria.

Question 10

The relationship between specific bacteria and specific diseases was first demonstrated by Koch.

Accepted Answer

Robert Koch is famously known for his postulates, which demonstrated the causal relationship between specific bacteria (such as Bacillus anthracis) and specific diseases (such as anthrax).

Question 11

__________ _____________microbiologists monitor community food establishments and water supplies in order to control the spread of communicable diseases.

Accepted Answer

The answer of __________ _____________microbiologists monitor community food establishments and...

Question 12

What is the most compelling reason why "protists" are not considered to be a taxonomic group?

Accepted Answer

The organisms often included in the protist group are very diverse and do not have a shared, defining feature that unites them as a cohesive taxon. Protists can be unicellular or multicellular, prokaryotic or eukaryotic, autotrophic or heterotrophic, and can have different modes of reproduction. Therefore, they are not considered a taxonomic group.

Question 13

__________ was the first to isolate a root nodule bacterium capable of nitrogen fixation.

Accepted Answer

The answer of __________ was the first to isolate a...

Question 14

__________ and __________ microbiology investigates the spoilage of products for human consumption and the use of microorganisms in the production of cheese,yogurt,pickles,beer,and the like.

Accepted Answer

The answer of __________ and __________ microbiology investigates the spoilage...

Question 15

The endosymbiotic hypothesis is generally accepted as the origin of two eukaryotic organelles: mitochondria and chloroplasts.

Accepted Answer

The endosymbiotic hypothesis proposes that mitochondria and chloroplasts were once free-living prokaryotes that were engulfed by another cell and eventually became integrated as organelles within eukaryotic cells. This hypothesis is widely accepted by the scientific community as the origin of these two organelles in eukaryotic cells.

Question 16

A new microbe has been discovered in the rumen of sheep.Microscopy shows no evidence of a nuclear membrane and biochemical studies of the cell wall demonstrate the lack of peptidoglycan.Metabolic studies show that this microbe generates methane.This microbe would most likely be classified in the:

Accepted Answer

The lack of a nuclear membrane and presence of methane production are both characteristics commonly found in organisms belonging to Domain Archaea. Additionally, some species of archaea have been found in the rumen of animals, making this classification even more likely. The absence of peptidoglycan in the cell wall rules out Domain Bacteria as an option, and the lack of fungal features rules out Kingdom Fungi and the possibility of Eukarya as a domain.

Question 17

__________ discovered that soil bacteria could oxidize iron,sulfur,and ammonia to obtain energy.

Accepted Answer

The answer of __________ discovered that soil bacteria could oxidize...

Question 18

The branch of microbiology that studies the relationship between microorganisms and their habitats is called __________ ______________.

Accepted Answer

The answer of The branch of microbiology that studies the...

Question 19

The branch of microbiology that deals with the mechanisms by which the human body protects itself from disease-causing organisms is called __________.

Accepted Answer

The answer of The branch of microbiology that deals with...
