Reproduction is the ability of the living organisms to 

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Show response to stimulus

  2. Adjust to the change in the climate

  3. Produce similar of its kind

  4. Show growth and development

Show answer
Correct Option: C
Explanation:

Reproduction is a process of producing offsprings from parents. It can be sexual, asexual or vegetative. Only sexual reproduction involves the fusion of gametes. It ensures continuity of a species by producing its own kind and also a transfer of genes in further generations.

So the correct option is 'Produce similar of its kind'.

Changes in structure and function of living beings is known as

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Adaptions

  2. Order

  3. Metabolism

  4. Development

Show answer
Correct Option: D
Explanation:

Changes in structure and function of living beings is called as development. Development is important in an organism for in survival in the competition of nature. Development leads to adaptations that increase the chances of survival of an organism. 

So the correct option is D "development".

A living organism can be unexpectional differentiated from a non-living thing on the basis of its ability for

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Reproduction

  2. Growth and movement

  3. Responsiveness to touch

  4. Interaction with environment and progressive evolution.

Show answer
Correct Option: A

Germination of seeds can be related to which of the following properties of the living organism?

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Reproduction

  2. Growth

  3. Response to stimulus

  4. Both B and C

Show answer
Correct Option: D
Explanation:
Seed germination in response to diurnal fluctuations of temperature. Diurnal fluctuations in temperature may initiate or accelerate germination in certain flowering plants, and the effectiveness of the stimulus varies according to the amplitude of fluctuation and the presence or absence of light. These seeds after germinating brow into a new plant.
So the correct option is D "both B and C".

The release of oxygen by the plant during photosynthesis can be related to which of the following characteristics of the living organism?

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Absorption

  2. Movement

  3. Response to stimuli

  4. None of the above

Show answer
Correct Option: D
Explanation:

Photosynthesis is a metabolic process done by plants to produce starch from carbon dioxide and water in presence of sunlight. During this process, residual oxygen atoms are turned to the oxygen molecules as a byproduct. So it's cannot be compared to absorption, movement, and response to stimuli.

So the correct option is D "none of the above".

The buds on the potato determine the which of the following ability of the living organism?

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Locomotion

  2. Growth

  3. Movement

  4. None of the above

Show answer
Correct Option: B
Explanation:

Buds of potato are a type of vegetative reproductive part of the potato. These buds can individually be grown as a whole new plant with proper habitat and nutrition. 

So the correct option is B "growth".

Stomata can be related to which of the following activity

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Locomotion

  2. Excretion

  3. Movement

  4. Reproduction

Show answer
Correct Option: B
Explanation:

Stomata are pores found on the surface ie. epidermis of the leaf. These are used for the exchange of gases and releasing water by the process of transpiration. In some plants, calcium salts are also excreted through these pores. So the correct option is B "excretion".

Which of the following is the characteristics of a living organism?

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. Homeostasis

  2. Metabolism

  3. Adaptation

  4. All of the above

Show answer
Correct Option: D
Explanation:
Homeostasis is the state of steady internal conditions maintained by living things. This dynamic state of equilibrium is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.
Metabolism is the chemical processes that occur within a living organism in order to maintain life.
Adaptation is the process of change by which an organism or species becomes better suited to its environment.
An organism shows all of the given characters. 
So the correct option is D "all of the above".

Plants are considered as living organism because

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. They are capable of movement.

  2. They are capable to locomote.

  3. They can breathe.

  4. Both A and C.

Show answer
Correct Option: D
Explanation:

As a response to external stimuli, the plants show movement. For eg. plants tend to move towards the source of light, this is positive phototropism. It is prominently seen in sunflower. It also shows hydrotropism in the roots.

It is proved experimentally that plants can breathe. The basic principle of breathing includes the exchange of gases. It is seen that plants absorb carbon dioxide and release oxygen.
So the correct option is D "both A and C."

The lifespan of the dog is .......... years.

biology biology : an introduction introduction to organization of life signs of life what is living?

  1. 12 to 18

  2. 18 to 24

  3. 6 to 12

  4. 12 to 20

Show answer
Correct Option: A
Explanation:
  • The ageing profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15 to 16 years.
  • Whereas the medium and large sized dogs typically live for 10 to 13 years and some giant dog breeds such as mastiffs, often live only for 7 to 8 years.
  • So, the average lifespan for a dog is 12- 18 years.
  • So, the correct answer is option '12-18 years'.
