One of the functional characteristics of life is excitability or responsiveness. This refers to:
A
the ability to maintain a stable internal environment
B
the process of producing offspring
C
the ability of an organism to sense changes in its environment and react to them
D
the process by which organisms convert nutrients into energy
Verified step by step guidance1
Understand the concept of excitability or responsiveness: This is a functional characteristic of life that refers to an organism's ability to sense changes in its environment and respond appropriately.
Compare the given options to the definition of excitability: Analyze each option to determine which aligns with the ability to sense and react to environmental changes.
Option 1: 'The ability to maintain a stable internal environment' refers to homeostasis, which is a different characteristic of life, not excitability.
Option 2: 'The process of producing offspring' refers to reproduction, another distinct characteristic of life, unrelated to responsiveness.
Option 4: 'The process by which organisms convert nutrients into energy' refers to metabolism, which is also separate from excitability. Therefore, the correct answer is Option 3: 'The ability of an organism to sense changes in its environment and react to them.'
