## CORE INFORMATION\n✓ **Answer**: D\n## CONCEPT FRAMEWORK\n\t**Primary Concept**: Dendrochronology\n\t**Related Topics**: Tree rings, Age determination\n\t**Prerequisites**: Basic knowledge of tree biology\n## SOLUTION PATHWAY\n**Given Information**:\n\tThe question asks for the definition of dendrochronology.\n**Method & Steps**:\n\t1. Recall the definition of dendrochronology.\n\t\tReasoning: Dendrochronology is the science of dating tree rings to determine the age of trees.\n\t\tFormula/Rule: N/A\n\t2. Identify the option that matches the definition.\n\t\tWorking: Option D, 'Determination of age of tree', is the correct definition.\n\t\tKey Point: The other options are related to tree biology but not specifically to age determination using tree rings.\n\t3. Select the correct option.\n\t\tResult: Option D is the correct answer.\n\t\tVerification: The definition aligns with the scientific meaning of the term.\n ## OPTION ANALYSIS\n[A] :x: Secondary growth refers to an increase in the thickness of a plant, not age determination.\n[B] :x: Apical growth is growth at the tips of roots and shoots, not related to age determination.\n[C] :x: Seasonal variation refers to changes due to different times of year, not the method of tree aging.\n[D] ✓: Determination of age of tree is the correct definition of dendrochronology.\n ## LEARNING AIDS\n\t**Common Mistakes**:\n\t\t1.[Error 1]: Confusing dendrochronology with general tree growth processes.\n\t\t\t[How to avoid]: Focus on the specific meaning of 'age determination' in the context of tree rings.\n\t**Quick Tips**:\n\t\t1.[Helpful shortcut]: Remember that 'dendro' relates to trees and 'chronology' relates to time or age.\n

The correct Option is "Determination of age of tree"

## CORE INFORMATION\n✓ **Answer**: D\n## CONCEPT FRAMEWORK\n\t**Primary Concept**: Organ Function Matching\n\t**Related Topics**: Human Biology, Anatomy, Sensory Organs\n\t**Prerequisites**: Basic understanding of human body parts and their functions.\n## SOLUTION PATHWAY\n**Given Information**:\n\tPairs of organs and their associated functions.\n**Method & Steps**:\n\t1. Analyze each pair to determine if the function correctly matches the organ.\n\t2. Identify the pair where the function does not match the organ.\n\tResult: Ear : Smell is the mismatch.\n\tVerification: The ear is responsible for hearing, not smell. The nose is responsible for smell.\n## OPTION ANALYSIS\n[A] ✓: Teeth : Chew - This is a correct match. Teeth are primarily used for chewing food.\n[B] ✓: Tongue : Taste - This is a correct match. The tongue is the primary organ for taste.\n[C] ✓: Skin : Feel - This is a correct match. Skin is the largest sensory organ and is responsible for the sense of touch.\n[D] :x: Ear : Smell - This is an incorrect match. The ear is responsible for hearing, while the nose is responsible for smell.\n## LEARNING AIDS\n\t**Common Mistakes**:\n\t\t1. Confusing the functions of different sensory organs: Review the functions of each sensory organ to avoid confusion.\n\t\t2. Overlooking the obvious: Double-check each option, even if it seems obvious, to ensure accuracy.\n\t**Quick Tips**:\n\t\t1. Visualize the function of each organ: Imagine using each organ to help remember its purpose.\n\t\t2. Create mnemonics: Use memory aids, like acronyms or rhymes, to remember the functions of different organs.
