  1. Pasteur

  2. Oparin

  3. Darwin

  4. Linnaeus

Show answer
Correct Option: D
Explanation:

Pasteur, Oparin and Darwin are the scientists who are known for their contributions in the field of microbiology, biochemistry (theory for the origin of life) and evolution (origin of species) respectively. Carl Linnaeus gave the Linnaean taxonomy and binomial nomenclature. The classification and the nomenclature were published in the book Systema Naturae which was written by Carl Linnaeus. The binomial nomenclature for the classification of the organisms is considered as an important contribution. 

Thus, the correct answer is option D.

  1. 2

  2. 3

  3. 4

  4. 5

Show answer
Correct Option: B
Explanation:
  • In Vedic times, the; living organisms were divided into 3 classes. They are
  1. Born from the womb (Jivagi)
  2. Born from egg (Andaja)
  3. Born from sprouts (Udbhija)
  • Hence In Vedic times, living organisms were classified into 3 classes.
  • So, the correct answer is '3'

Which of the following things grow? 

zoology living and non living characteristics of life attributes of living organisms signs of life biology : an introduction living world and classification

  1. Road

  2. Pen

  3. Water

  4. Tree

Show answer
Correct Option: D
Explanation:

The living organisms are composed of cells. The cells divide and the body of the organisms show growth due to the increase in the number of cells. The trees are the living organisms and show the process of growth. Road, pen and water are non-living organisms which do not show the process of growth. 

Thus, the correct answer is option D. 

Organisms respond to environment stimuli which would be

  3. Biologocal

  4. All the above

Show answer
Correct Option: D
Explanation:

Stimuli can be of any type whether physical or mechanical, biological as in response to another organic thing or chemical including chemical compounds or environment.

So the correct option is 'All of the above'.

  1. methane

  2. ethane

  3. oxygen

  4. nitrogen

Show answer
Correct Option: A
Explanation:

Microbial conversion of organic matter to methane called Biogas has become attractive as a method of waste treatment and resource recovery. This process is anaerobic(absence of oxygen) and is carried out by action of various groups of anaerobic bacteria.
Three basic points about this process are that most of the important bacteria involved in biogas production process are anaerobes and slow growing, a greater degree of metabolic specialization is observed in these anaerobic microorganisms and that most of the free energy present in the substrate is found in the terminal product methane. Since less energy is available for the growth of organism, less microbial biomass is produced and, consequently, disposal of sludge after the digestion may not be a major problem.
Hence, the statement is false.
