Questions Related to living world and classification of microbes

Which one of the following does not find a heterotrophs place in five kingdom system of classification?

biology living world and classification of microbes modern classification system traditional method of animal classification salient features of five kingdoms classification hierarchy hierarchy of classification

  1. Bacteria

  2. Lichens

  3. Cyanobacteria

  4. Viruses

Show answer
Correct Option: D
Explanation:

Viruses are considered to be acellular as they do not have a defined cell wall, cell membrane, nucleus or nucleoid, cytoplasm and cellular organelles. For this reason, they cannot perform their metabolic activities on their own and are obligately dependent on the host cell machinery. Therefore, they do not find a place in the five-kingdom classification system. 

A. Bacteria are classified under Kingdom Monera as they have a prokaryotic cell.
B. Lichens are grouped under Kingdom Fungi.
C. Cyanobacteria are photosynthetic prokaryotes grouped under Kingdom Monera.
D. No kingdom is ascribed to the viruses.
Hence, the correct answer is 'Viruses'

Which of the following is the most commonly used classification scheme?

biology living world and classification of microbes modern classification system traditional method of animal classification salient features of five kingdoms

  1. Linnaeus, five kingdom scheme

  2. Whittaker, five kingdom scheme

  3. Darwin, five kingdom scheme

  4. Hooke, five kingdom scheme

Show answer
Correct Option: B
Explanation:
R.H. Whittaker proposed the five kingdom classification in the year 1969. It is the modern or latest classification system of organisms which is most commonly used. It classifies the organisms in the groups Monera, Protista, Fungi, Plantae and Animalia. The classification is performed on the basis of the structure of cell, complexity of organisms, mode of nutrition and phylogenetic relationship.
Thus, the correct answer is option B.

Carolus Linnaeus was from

biology living world and classification of microbes modern classification system traditional method of animal classification salient features of five kingdoms

  1. Sweden

  2. U.K

  3. Holland

  4. France

Show answer
Correct Option: A
Explanation:

Carolus Linnaeus (23 May 1707 10 January 1778), also known as Carl von Linn or Carl Linnaeus was a Swedish botanist, zoologist, and taxonomist, who established conventions for naming living organisms still in general scientific use today, which is called as the binomial nomenclature. 
Thus, the correct answer is option A.

Choose the incorrect match from the following in Whittaker's classification.

biology living world and classification of microbes modern classification system traditional method of animal classification salient features of five kingdoms

  1. Archeae - Monera

  2. Diatoms - Protista

  3. Lichens - Fungi

  4. Green algae - Plantae

Show answer
Correct Option: C
Explanation:
A lichen is not a single organism, but the result of a partnership (mutualistic symbiosis) between a fungus and an alga or cyanobacteria. So they are not particularly classified under one single kingdom because it consists of two or more mutualistic symbiotic organisms.
So the correct option  is 'Lichens -fungi'.

.............. is a kind of allergy

zoology living world and classification of microbes allergy and autoimmune diseases allergy non infectious diseases

  1. Asthma

  2. Yellow eyes

  3. Typhoid

  4. Mumps

Show answer
Correct Option: A
Explanation:

An allergy is a hypersensitivity disorder of the immune system. Symptoms include red eyes, itchiness, and runny nose, eczema, hives, or an asthma attack. Out of the given options, only asthma is an allergy. Asthma and allergies often go hand-in-hand. Asthma is a disease of the branches of the windpipe (bronchial tubes), which carry air in and out of the lungs. There are several different types of asthma. Allergic asthma is a type of asthma that is triggered by an allergy (for example, pollen or mold spores).

  1. Aedes aegypti

  2. Culex fatigans

  3. Anopheles

  4. Aedes donovoni

Show answer
Correct Option: A
Explanation:

Dengue fever is a mosquito-borne disease caused by the dengue virus. There is a characteristic skin rash that is similar to measles. It is transmitted by several species of mosquito within the genus Aedes, mainly Aedes aegypti.
Therefore, the correct answer is option A.

  1. Culex

  2. Aedes

  3. Anopheles

  4. None of the above

Show answer
Correct Option: B
Explanation:

Break bone fever is another name for dengue fever. It is a mosquito-borne tropical disease caused by the dengue virus. It is transmitted by several species of the mosquito within the genus Aedes aegypti.
Therefore, the correct answer is option B.

  4. Fungus

Show answer
Correct Option: A
Explanation:

Influenza is commonly known as 'flu' and is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness and at times can lead to death. The best way to prevent the flu is by getting a flu vaccination each year.

  1. Aedes

  2. Male Anopheles

  3. Female Anopheles

  4. Tsetse fly

Show answer
Correct Option: A
Explanation:

Aedes aegypti, the principal mosquito vector of dengue viruses is an insect closely associated with humans and their dwellings. People not only provide the mosquitoes with blood meals but also water-holding containers in and around the home needed to complete their development. The mosquito lays her eggs on the sides of containers with water and eggs hatch into larvae after a rain or flooding. A larva changes into a pupa in about a week and into a mosquito in two days.
