Question

Match the correct set.

A. Diapause	1. Deep winter sleep after accumulation of body fat.
B. Hibernation	2. A change in the properties of an organism at genetic level in response to environment.
C. Phenotypic adaptation	3. Interaction of an orchid growing on mango tree.
D. Commensalism	4. Physiological state of dormancy with very specific triggering and releasing conditions being suspended growth.

• A. A- 1, B- 2, C- 4, D- 3
• B. A- 1, B- 3, C- 2, D- 4
• C. A- 3, B- 1, C- 3, D- 2
• D. A- 4, B- 1, C- 2, D- 3

Answer 1

The correct option is D A- 4, B- 1, C- 2, D- 3

• Diapause is a period during which growth or development is suspended and physiological activity is diminished. Example in arthropods mainly in insects.
• Hibernation is an extended period of deep sleep. It is a state of inactivity and metabolic depression in endotherms.Example polar bears show hibernation.
• Phenotypic adaptation involves changes in the body of an organism in response to genetic mutation or certain environmental changes. For example, desert plants have thick cuticles and sunken stomata on the surface of their leaves to prevent transpiration.
• Commensalism is an association between two organisms in which one benefits and the other one neither benefits nor harm. For example, the interaction of an orchid growing on a mango tree where the orchid receives benefits from a mango tree and the mango tree is unaffected.

Therefore, the correct answer is option D.
