Which of the following things grow? 

  1. Road

  2. Pen

  3. Water

  4. Tree
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

Biomass ferments to form _________ in the presence of air.

  1. methane

  2. ethane

  3. oxygen

  4. nitrogen
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

The organism made up of many cells are known as 

  1. Acellular

  2. Unicellular

  3. Multicellular

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The living organisms are composed of cells which forms the structural and functional unit of the life forms. Some of the animals are composed of only one cell which forms the complete body are known as unicellular. Some of the animals are composed of many cells which form tissues and organs are known as multicellular. 

Thus, the correct answer is option C.

C Correct answer
Explanation

Under adequate and favourable conditions, the lifespan of a

  • Fruit fly is 40-50 days.
  • Crocodile is nearly 70-100 years, depending on the species.
  • Parrot is from 50-95 years, depending on the species.
  • Banyan tree is 200 years.
  • Crow is 7-22 years, depending on the species.
  • Butterfly is from weeks to months, depending on the species.
  • Tortoise is 150 years.
Thus, the correct answer is 'Fruitfly<Crocodile<Parrot<Banyan tree.'
