  1. White muscles

  2. Proper wing span

  3. Pneumatic bones

  4. Red muscles

Show answer
Correct Option: D
Explanation:

Red muscles stores ATP in large amount as they ahave abundant of mitochondria in them since house sparrow lacks red muscles it does not have sufficient energy for long flights.

So, the correct option is 'Red muscles'.

Most names in biological nomenclature of living organisms are taken from which language?

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

  1. Hindi

  2. Latin

  3. German

  4. French

Show answer
Correct Option: B
Explanation:

The original scientific names were taken from Latin and Greek languages. New names are now derived either from Latin language or are latinised. This is because Latin language is dead and therefore, it will not change in form or spellings with the passage of time.

A living organism is unexceptionally differentiated from a non-living structure on the basis of

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

  1. Reproduction

  2. Growth and movement

  3. Interaction with environment

  4. Responsiveness

Show answer
Correct Option: D
Explanation:
All organisms, from primitive prokaryotes to most advanced and complex eukaryotes, are able to sense and respond to environmental factors. The stimuli are perceived by sense organs in higher animals through sensory receptors in the eyes, ears, nose etc. Plants do not possess such sense organs. However, they do respond to external factors such as light, water, temperature, pollutants, other organisms, etc. Human beings have an additional facility of self consciousness (awareness of self). Consciousness and response to stimuli are said to be defining properties of living organisms.
So the correct option is D.

Read the following statements and select the correct ones.


(i) An increase in mass is a characteristic of living organisms
(ii) Metabolic reactions can be demonstrated outside the body in isolated cell-free systems.
(iii) 'Response to stimuli' is a defining property of living organisms.

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. (ii) and (iii)

  3. (i) and (iii)

  4. (i), (ii) and (iii)

Show answer
Correct Option: D
Explanation:

(i) Increase in mass and increase in number of individuals are twin characteristics of growth is true
(ii) Metabolic reactions can be demonstrated outside the body in isolated cell-free systems is true
(iii) 'Response to stimuli' is a defining property of living organisms is true

So, the correct option is '(i), (ii) and (iii)'.

There are various types of reproduction. The type of reproduction adopted by an organism depends on

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

  1. The habitat and morphology of the organism

  2. Morphology of the organism

  3. Morphology and physiology of the organism

  4. The organisms habitat, physiology and genetic makeup

Show answer
Correct Option: D
Explanation:
There are various types of reproduction, both asexual (fission, budding, etc.) and sexual (internal and external). The type of reproduction, an organism undergoes depends ultimately on its genetic makeup which influences its physiology. Habitat also influence the type of reproduction, that organism undergoes.
So, the correct answer is 'The organisms habitat, physiology and genetic makeup'.

The ascending or descending arrangement of taxonomic categories is called as.

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

  1. Classification

  2. Taxonomy

  3. Hierarchy

  4. Key

Show answer
Correct Option: C
Explanation:

Hierarchy of categories is the classification of organisms in a definite sequence of categories(taxonomic categories) in a descending order starting from kingdom and reaching upto species or an ascending order from species of kingdom.

The scientific name of banyan is written as Ficus benghalensis L. Which of the following statements is correct regarding this?

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

  1. Letter L. signifies Latin language

  2. The name should be written reverse with benghalensis preceding Ficus

  3. Letter L. signifies the taxonomist Linnaeus

  4. Benghalensis is a generic name

Show answer
Correct Option: C
Explanation:

In binomial nomenclature, the first or generic word starts with a capital letter while the second word or specific epithet starts with a small letter. The name of taxonomist appears after the specific epithet, i.e., at the end of the biological name and is written in abbreviated form, e.g., Ficus benghalensis L., indicates that this species was first described by Linnaeus.

___________ is a life process that is not essential for an individual's survival but for survival of the species.

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. Respiration

  4. Nutrition

Show answer
Correct Option: B
Explanation:
Reproduction is a biological process in which an organism produces young ones (offspring) of the same species. It is one of the most important characteristic of the living organisms. Reproduction is essential for the survival of species but not for the survival of individuals.
So, the correct answer is 'Reproduction'.
