The high boiling point of water is advantageous to living organisms because

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

  1. The environment seldom reaches the boiling point of water

  2. Organisms can easily boil off enough water to keep themselves cool

  3. It allows organisms to spread heat evenly throughout their bodies

  4. Organisms can absorb a great deal of heat before they reach the boiling point from organisms and population

Show answer
Correct Option: D
Explanation:

The high boiling point of water is advantageous to living organisms because organisms can absorb a great deal of heat before they reach the boiling point from organisms and population. Thus the organisms will not be affected by the high temperature because water can absorb the heat and maintain its homogeneity by uniformly dissipating it.


So the correct option is 'Organisms can absorb a great deal of heat before they reach the boiling point from organisms and population'.



Among the following choose the properties shown by the living organism exclusively.


I. Growth
II. Increase in mass
III. Self-replication ability
IV. Response to touch stimuli

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

  1. I and II

  2. I, II and III

  3. III and IV

  4. I, II, III and IV

Show answer
Correct Option: C
Explanation:
self replicating ability, also known reproduction and responding to or reacting to changes in the internal or external environment is called responsiveness to stimulus are both properties exclusive to living organisms
So, the correct answer is 'III and IV'

  1. C , H, O, P

  2. C , H, O

  3. C, H, N ,P

  4. C , H, O, N, P

Show answer
Correct Option: A
Explanation:
  • Organic compounds are macromolecules or compounds associated with life processes such as carbohydrates, proteins, lipids, nucleic acids.
  • The main constituents of this organic compond are Carbon, hydrogen, oxygen and phosphorous.
  • In carbohydrates, the main components are carbon, hydrogen and oxygen atoms.
  • Eg- Glucose- is a single-unit carbohydrate or monosaccharide with six carbon atoms, 12 hydrogen atoms, and six oxygen atoms.
  • In proteins,  the main components are carbon, hydrogen, oxygen, and nitrogen atoms.
  • Eg- Any amino acid has a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain).
  • Nucleic acids contains carbon atoms, phosphate and nitrogenous base.

The most important characteristics of living organisms is

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

  1. Multiplication

  2. Movement

  3. Growth

  4. Protoplasm

Show answer
Correct Option: D
Explanation:

The most important characteristic defining an organism as living is the presence of protoplasm in it's cells. While the other three options which are multiplication, movement and growth can not define living to the full extent. As plants are immobile yet they are living. The external growth of mountains, boulders, and sand is observed. Mules, sterile worker bees and sterile couples can not multiply but they are living organisms.

So, an important characteristic of living organisms is 'Protoplasm'.

The property which is present universally in living organism is

  1. Reproduction

  2. Metabolism

  3. Cellular organisation

  4. Growth

Show answer
Correct Option: B

Which characteristic distinguishes living organism unexceptionally from the non-living?

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

  1. Metabolism

  2. Reproduction

  3. Movement

  4. Interaction with the environment

Show answer
Correct Option: A
Explanation:

  1. Metabolism occurs 'unexceptionally in all living organisms' and this is a defining feature of living beings. 
  2. Reproduction is absent in sterile or infertile living beings.
  3. Organisms like the majority of sponges and plants do not move, but they're still living.
  4. Patients in a coma do not interact with the environment, yet all the metabolic processes occur thus they are living.
So, the correct option is "Metabolism",

How many of the following organisms have a lifespan of more than 20 years?

  1. 3

  2. 4

  3. 5

  4. 6

Show answer
Correct Option: C
Explanation:

Life span : The period from birth to the natural death of an organism. Life span can never be correlate with the size of animals. Life span of some animals are given below ;

  • Elephant - 60-90 years
  • Parrot - 100 - 140 years
  • Dog - 20 - 30 years
  • Rose - 5 - 7 years
  • Crow - 15 years
  • Banyan tree - 200 years
  • Crocodile - 60 years
  • So the correct answer is " 5 ".

The living organisms can be unexceptionally distinguished from the non-living things on the basis of their ability for

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

  1. Growth

  2. Reproduction

  3.  Movement

  4. Responsiveness to touch

  5. All of the above

Show answer
Correct Option: E
Explanation:

Living things are lively and active and exhibit characteristics of life, like growth, movement, reproduction, response to stimuli (like touch, smell, light) . These activities are done by the cells of which the living things are made up of. Some examples of living things around us are human beings, animals, plants and microorganisms.

So, the correct answer is 'All of the above'.
