Question

State whether the following statements are true or false .
Homeostasis is achieved by morphological, physiological and behavioural adaptations

• A. True
• B. False

Answer 1

The correct option is A True

Homeostasis is maintaining constant conditions inside living organisms. These might be in terms of maintenance of pH, temperature, osmolarity etc. Organisms achieve homeostasis by various adaptations. This can be understood with the example of temperature regulation in different organisms-

• Morphological adaptation - thick blubber and fur coat in polar bears for maintaining body temperature in cold temperature.
• Physiological adaptation - sweating to bring down body temperature in summer.
• Behavioral adaptation - Desert lizards lack the physiological ability that mammals have to deal with the high temperatures of their habitat but manage to keep their body temperature fairly constant by behavioral means. They bask in the sun and absorb heat when their body temperature drops below the comfort zone, but move into the shade when the ambient temperature starts increasing.

So, the correct option is 'True'.
