II. increase in mass
III. self-replication ability
IV. response to touch stimuli

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
	**Primary Concept**: Defining characteristics of life
	**Related Topics**: Biology, Life processes, Reproduction, Growth, Sensitivity
	**Prerequisites**: Basic understanding of living vs. non-living things.
## SOLUTION PATHWAY
**Given Information**:
A list of properties and the requirement to identify those exclusive to living organisms.
**Method & Steps**:
	1. Analyze each property for its presence in living organisms.
	2. Determine if the property is exclusive to living organisms or if non-living things can also exhibit it.
	3. Select the combination of properties that are exclusively found in living organisms.

## OPTION ANALYSIS
[A] :x: I and II (growth and increase in mass): While growth and increase in mass are common in living organisms, non-living things like crystals can also increase in mass.
[B] :x: II and IV (increase in mass and response to touch stimuli): As explained above, increase in mass isn't exclusive to life.  While living organisms respond to stimuli, some non-living materials also react to touch (e.g., piezoelectric materials).
[C] ✓: I and III (growth and self-replication ability): Growth, in the biological sense, involves the organized development of an organism, which is exclusive to living things. Self-replication, the ability to produce offspring, is a fundamental characteristic of life.
[D] :x: III and IV (self-replication ability and response to touch stimuli): While self-replication is exclusive to life, response to touch, as explained earlier, is not.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing 'increase in mass' with biological growth:  Biological growth is more complex than simply adding mass. It involves structured development and cellular differentiation.
		2. Considering any response to external factors as a sign of life:  Many non-living things react to external changes, but these reactions are fundamentally different from the responses of living organisms.
	**Quick Tips**:
		1. Focus on the fundamental processes that define life:  These include self-replication, growth (in the biological sense), metabolism, adaptation, and response to stimuli in a coordinated manner.
		2.  Remember that exclusivity is key: The property must be exhibited *only* by living organisms to be considered a defining characteristic of life.
