Questions and Answers

1.

Are micro organisms classified as living things?
- A.
  
  Yes
- B.
  
  No
- C.
  
  None of the above
- D.
  
  All of the above
Correct Answer
A. Yes

Explanation
Microorganisms are classified as living things because they possess the fundamental characteristics of life. They are capable of growth, reproduction, and metabolism. They can respond to stimuli from their environment and adapt to changes. Microorganisms also have genetic material and can evolve over time. Therefore, they meet the criteria for being considered living organisms.

Prokaryotic organisms are conventionally classified as?
- A.
  
  Distributing membrane-bound organelles
- B.
  
  Possessing membrane-bound organelles
- C.
  
  Lacking membrane-bound organelles ..
- D.
  
  None of the above
Correct Answer
C. Lacking membrane-bound organelles ..

Explanation
Prokaryotic organisms are conventionally classified as lacking membrane-bound organelles. Unlike eukaryotic organisms, prokaryotes do not have membrane-bound organelles such as mitochondria, endoplasmic reticulum, or Golgi apparatus. Instead, their genetic material is found in a single circular chromosome in the cytoplasm, and their metabolic processes occur in the cytoplasm as well. Prokaryotes may have other structures within their cytoplasm, such as ribosomes and inclusion bodies, but these are not considered membrane-bound organelles. Therefore, the correct answer is lacking membrane-bound organelles.

Are viruses classified as micro organisms?
- A.
  
  No
- B.
  
  Yes
- C.
  
  None of the above
- D.
  
  Indecisive
Correct Answer
B. Yes

Explanation
Viruses are classified as microorganisms because they are microscopic in size and exhibit characteristics of living organisms, such as the ability to replicate and evolve. While they are not considered to be alive in the traditional sense because they lack cellular structure and cannot carry out metabolic processes on their own, they are still classified within the realm of microorganisms due to their small size and ability to cause infectious diseases.

Bacteria can be used for the industrial production of?
- A.
  
  Amino-acids
- B.
  
  Litter
- C.
  
  Diseases
- D.
  
  Spirogyra
Correct Answer
A. Amino-acids

Explanation
Bacteria can be used for the industrial production of amino acids. Bacteria have the ability to synthesize various amino acids, which are essential building blocks for proteins. Through genetic engineering techniques, bacteria can be modified to produce specific amino acids in large quantities. These amino acids can then be used in various industries such as food, pharmaceuticals, and agriculture. Bacterial production of amino acids is a cost-effective and sustainable method compared to traditional chemical synthesis methods.

Can micro organisms be seen with the naked eye?
- A.
  
  Yes
- B.
  
  No
- C.
  
  Indecisive
- D.
  
  None of the above
Correct Answer
B. No

Explanation
Microorganisms cannot be seen with the naked eye because they are too small to be visible without the aid of a microscope. Microorganisms include bacteria, viruses, fungi, and protozoa, and their sizes range from a few micrometers to even smaller sizes. Due to their microscopic nature, they require magnification to be observed and studied.

The following are the branches of microbiology except?
- A.
  
  Virology
- B.
  
  Sexology
- C.
  
  Mycology
- D.
  
  Protozoology
Correct Answer
B. Sexology

Explanation
Sexology is not a branch of microbiology. Microbiology is the study of microorganisms, including viruses, bacteria, fungi, and protozoa. Virology is the study of viruses, mycology is the study of fungi, and protozoology is the study of protozoa. Sexology, on the other hand, is the scientific study of human sexuality and sexual behavior. It is not directly related to the study of microorganisms.

Microorganisms or microbes are microscopic organisms that exist as the following except?
- A.
  
  Unicellular
- B.
  
  Bi-cellular
- C.
  
  Multicellular
- D.
  
  Cell clusters.
Correct Answer
B. Bi-cellular

Explanation
Microorganisms or microbes are microscopic organisms that exist as unicellular, multicellular, or cell clusters. However, they do not exist as bi-cellular organisms. This means that they are either single-celled or form cell clusters, but they do not have two distinct cells like bi-cellular organisms.

The following are types of microbes except?
- A.
  
  Fungi
- B.
  
  Bacteria
- C.
  
  Disease
- D.
  
  Viruses
Correct Answer
C. Disease

Explanation
The question asks for types of microbes, and the answer "Disease" does not fit this category. Microbes refer to microscopic organisms such as fungi, bacteria, and viruses. "Disease" is a health condition caused by microbes or other factors, but it is not a type of microbe itself.

Rate this question:
9.

The following are examples of microbes except?
- A.
  
  Salmonella
- B.
  
  E. coli
- C.
  
  Listeria
- D.
  
  All of the above
Correct Answer
A. Salmonella

Explanation
Salmonella is not an example of a microbe because it is a genus of bacteria that causes food poisoning in humans and animals. It is not a type of microorganism, such as bacteria, viruses, fungi, or protozoa. On the other hand, E. coli and Listeria are examples of microbes. E. coli is a type of bacteria commonly found in the intestines of humans and animals, while Listeria is a genus of bacteria that can cause serious infections in humans. Therefore, the correct answer is Salmonella.

The following are diseases caused by microbes except?
- A.
  
  Common cold
- B.
  
  Measles
- C.
  
  Chicken Pox
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
The correct answer is "All of the above." This means that common cold, measles, and chickenpox are all diseases caused by microbes.
