House sparrow can fly for short distances only because of the absence of 

  1. White muscles

  2. Proper wing span

  3. Pneumatic bones

  4. Red muscles
Reveal answer Fill a bubble to check yourself
D Correct answer
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?

  1. Hindi

  2. Latin

  3. German

  4. French
Reveal answer Fill a bubble to check yourself
B Correct answer
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

  1. Reproduction

  2. Growth and movement

  3. Interaction with environment

  4. Responsiveness
Reveal answer Fill a bubble to check yourself
D Correct answer
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.

  2. Morphology of the organism

  3. Morphology and physiology of the organism

  4. The organisms habitat, physiology and genetic makeup
Reveal answer Fill a bubble to check yourself
D Correct answer
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'.

  4. Benghalensis is a generic name
Reveal answer Fill a bubble to check yourself
C Correct answer
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.
