  1. True

  2. False

Show answer
Correct Option: A
Explanation:

Response to stimuli also known as sensitivity is shown by all the living organisms whether it is unicellular or multicellular. This is essential for one-celled organisms for their survival. For example, if a unicellular organism is exposed to a chemical, it will react either by producing another chemical or by moving away from the stimulus to survive. 

Thus, the correct answer is option A.

  3. The species epithet only

  4. Any rank of taxonomic hierarchy
