Question

Which of the following processes demonstrates adaptation in living organisms?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Biological Adaptation
 **Related Topics**: Evolution, Natural Selection, Phenotype, Genotype
 **Prerequisites**: Basic understanding of biology and evolution.
## SOLUTION PATHWAY
**Given Information**:
  Four options describing different processes.
  The question asks for a process demonstrating adaptation in living organisms.
**Method & Steps**:
 1. Analyze each option to determine if it represents an adaptation.
  Reasoning: Adaptation is a trait that enhances an organism's survival and reproduction in its environment.  It's a heritable characteristic.
  Formula/Rule: None directly applicable.
 2. Evaluate each option based on the definition of adaptation.
  Working:
  A. Stone weathering is a geological process, not a biological adaptation.
  B. Rust formation is a chemical process, not a biological adaptation.
  C. Camouflage in a chameleon is a heritable trait that improves its survival by allowing it to avoid predators. This is a classic example of adaptation.
  D. Sugar dissolving in water is a physical process, not a biological adaptation.
 3. Select the option that represents a biological adaptation.
  Result: Option C, the development of camouflage in a chameleon.
  Verification: The chameleon's camouflage is a heritable trait that directly increases its survival chances, fitting the definition of adaptation.
 ## OPTION ANALYSIS
A :x: Stone weathering is a geological process, not a biological one. It does not involve living organisms adapting to their environment.
B :x: Rust formation is a chemical reaction, unrelated to biological adaptation.
C ✓: The development of camouflage in a chameleon is a clear example of adaptation.  The chameleon's colour change is a heritable trait that enhances its survival and reproductive success by providing protection from predators.
D :x: Sugar dissolving in water is a physical process and has nothing to do with biological adaptation.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing adaptation with acclimation: Acclimation is a short-term, non-heritable adjustment to the environment, while adaptation is a long-term, heritable change.
  2.Choosing examples of phenotypic plasticity without a genetic basis:  While phenotypic plasticity can be adaptive, the question focuses on heritable traits.
 **Quick Tips**:
  1.Focus on heritable traits that enhance survival and reproduction.
  2.Remember that adaptation is a result of natural selection acting on genetic variation.
