Questions Related to living and non living

A dead organism does not grow. Although, some non-living things can increase in size e.g. mountains, stones. The process is called ______

  1. accretion

  2. accumulation

  3. adaptation

  4. organisation


Correct Option: A
Explanation:

  • Non-living things increase in size due to the addition of similar materials to their outer surface, they include crystals, glaciers, stones and mountains

So, the correct answer is 'accretion'

Living organisms must maintain a constant internal environment.

  1. True

  2. False


Correct Option: A
Explanation:

Living organisms must maintain a constant internal environment while living in a constantly changing external environment. Maintaining the internal environment is important because the processes that keep the cell alive can only take place under certain conditions. There are different processes that occur in the body to maintain the constant internal environment such as diffusion, osmosis, homeostasis, active transport, passive transport, endocytosis, exocytosis, etc. Homeostasis helps to maintain an equilibrium of an internal environment. 

So, the correct answer is 'True'

Characteristics of living things are

  1. Made up of cells

  2. Growth

  3. Response

  4. All of the above


Correct Option: D
Explanation:

All living things and dead are made up of the cells which perform life processes for maintaining life. They give the response to the stimulus or environmental factors. But growth is the characteristic of both living and dead as dead like wood shows growth by the absorption of water. Thus, the growth is the characteristics of living things but not the defining or fundamental properties of living things. Hence, the correct answer is option D.

What is Gilotin?

  1. Mine of Coal

  2. Human Settlement

  3. Death Machine

  4. Shifting Agriculture


Correct Option: C
Explanation:

The guillotine is a device designed for carrying out executions by decapitation. It consists of a tall upright frame in which a weighted and angled blade is raised to the top and suspended. The condemned person is secured at the bottom of the frame, with his or her neck held directly below the blade. The blade is then released, to fall swiftly and sever the head from the body.

In nonliving things

  1. Growth occurs from inside

  2. Growth occurs from outside

  3. Reproduction is asexual

  4. Cell is the structural unit


Correct Option: B
Explanation:
  • Non-living things do not grow through internal metabolic functions but by adding on from the outside. Non-living things do not need the energy to continue to exist. Some nonliving things such as crystals grow by accumulating more of the same material of which they are made.
  • Living things exhibit growth, movement, reproduction, respiration and metabolism. Living things use energy, respond to stimuli and adapt to their environment.
  • So, the correct answer is 'Growth occurs from outside'.

The structural unit of a nonliving being is

  1. Electron

  2. Neutron

  3. Cell

  4. Atom


Correct Option: D
Explanation:

Non-living beings are made up of a single or combination of molecules repeated in a sequence or randomly arranged. A molecule is a group of two or more atoms bound by chemical bonds. A few examples of non- living being is water, table, ground.

So, the correct answer is 'Molecule'.

An example of living organism is/are

  1. Bacteria

  2. Plant roots

  3. Earthworm

  4. Both A and C


Correct Option: D
Explanation:

The bacteria is a unicellular living organism which has been included in the group of prokaryotes. The earthworm is an example of segmented worm which belongs to the phylum Annelida. These are the living organisms which can perform the different biological processes like respiration, digestion, reproduction, etc. The plant roots cannot perform the functions without the other parts of the plants like leaves which produce food. 

Thus, the correct answer is option D. 

Which of the following helps in decomposition in soil and increases its nutrient content in the soil?

  1. Fungi

  2. Virus

  3. Protozoa

  4. None of the above


Correct Option: A
Explanation:

Fungi feed by saprophytic mode of nutrition on dead and decaying plants and animals. In this, the fungi release enzymes on the dead organism and break down complex substances into simpler substances. They absorb the required amount of released nutrients and release the rest in the soil hence increase its nutrient content.

So, the correct answer is 'Fungi'.

The structural unit of a non-living thing is

  1. Electron

  2. Neuron

  3. Cell

  4. Molecule


Correct Option: D
Explanation:

Electron is a stable sub-atomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids. 

Molecule is a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction. 
Cell is the structural unit of a living being.  
A neuron is an electrically excitable cell that processes and transmits information through electrical and chemical signals. 

Find the odd one out.

  1. Cotton shirt

  2. Shoe

  3. Pen

  4. Paper


Correct Option: C
Explanation:

The odd one out is the pen. The pen is generally made up of plastic. Plastic or polyvinyl chloride is a synthetic material. The material is non-biodegradable and cannot be degraded due to the activity of the microbes. The other examples are cotton shirt, shoe made up of leather and paper are biodegradable.

Thus, the correct answer is option C.
