Select the correct option for biological names.

  1. They are binomial

  2. They are descriptive

  3. They are universal

  4. All of these


Correct Option: D
Explanation:

The scientific names or biological names consist of two components- a generic name and a specific epithet. The name with two components are called binomial.
The scientific names are universal, being used all over the world irrespective of the language of the people. They are often descriptive, indicating some important characteristic of the organism.


Life span of Parrot is

  1. 25 yrs

  2. 50 yrs

  3. 140 yrs

  4. 15 yrs


Correct Option: C
Explanation:

Each organism has a specific lifespan in which it grows, undergoes a reproductive phase and then dies. Different organisms have a different lifespan.

the approximate lifespan of the parrot is 140-150 years. It has quite a long lifespan then any other birds.

So, the correct option is '140y years'

Which of the following improves the capacity of an organism to survive in a particular environment?

  1. Growth

  2. Reproduction

  3. Repair

  4. Adaptation


Correct Option: D
Explanation:

Adaptation is the ability of an organism to modify or change according to the conditions of the environment. This ability allows the organism to change some of the structures permanently and evolve to form a more sustainable organism. This property improves the chances of survival of the organism in a particular area. 

Thus, the correct answer is option D. 

The process of taking in and giving out of the air is known as 

  1. Breathing

  2. Inhaling

  3. Exhaling

  4. None of the above


Correct Option: A
Explanation:
Breathing is process of taking in and giving out of the air for exchange of gases between the internal of body and the external environment. The taking in of air is called as inhalation and giving out of air is called exhalation. It is an important part of respiration and can be done by various organs like nose, skin, gills.
Hence the correct option is A "breathing".

The living and non-living things can be distinguished by 

  1. The living things cannot move

  2. The living things need food

  3. The living things cannot perform respiration

  4. Both B and C


Correct Option: B
Explanation:
The living things require energy for all basic activities like respiration, movement, reproduction. This energy is obtained by break down of food, therefore, living things need food. But non-living things do not require such energy thus they do not need food.
Hence correct option is B "The living things need food".

The removal of the wastes from the body is known as 

  1. Excretion

  2. Digestion

  3. Extraction

  4. Ingestion


Correct Option: A
Explanation:

Excretion is process by which nitrogenous waste is thrown out of body. It is done to avoid toxicity in body by the waste, maintain pH and water level. It's done by various organs like kidney in human, nephridia in worms, etc.

So, the correct option is 'Excretion'.

The change that takes place in the body of the organism when a stimulus is provided is known as 

  1. Adaptation

  2. Response

  3. Growth

  4. None of the above


Correct Option: B
Explanation:
An adaptation is a feature that helps an organism, such as a plant or animal, survive in its environment.
A response can be defined as any change in the behavior of a living organism that results when an external or internal stimulus is provided. Growth is an irreversible, permanent increase in the size of an organ or its parts or even of an individual cell.
So, the answer is B.

It is much easier for a small animal to run uphill than for a large animal because

  1. the efficiency of muscles in large animals is less than in small animals

  2. it is easier to carry small body weight

  3. smaller animals have a higher metabolic rate

  4. small animals have a lower $O _2$ requirement.


Correct Option: C
Explanation:
Metabolic rate is directly proportional to the size of an animal. Larger the animal, lower is the metabolic rate.
Small animals can run uphill than a large animal because of their fast metabolic rate.
So, the correct option is 'smaller animals have a higher metabolic rate'
