Which among the following is not true for adaptation process?

Which among the following is not true for adaptation process? Correct Answer Acclimatisation is a type of adaptation.

Concept:

Charecteristics     Adaptation       Acclimatization
Definiation Adaptation is a heritable change in structure or function that improves an organism's fitness in a changing environment. Acclimatization is the process by which an organism adjusts to a harsh environment by allowing it to retain performance in a variety of settings.
Temporary or Permanent  Permanent change  Temporary change 
Speed  slow, requires thousands of years for evolution to take place faster, no requirement to enter the evolutionary process.
Type of Change  Heredity changes are seen which are permanent for the group of a particular species population.  Changes are not heredity. They are temporary 
Changes in body structure Physical as well as chemical changes are seen in the body.  Only physical changes are seen which are not permanent. 
Factors causing it Changing climatic conditions  entering a stressful environment. 
Reversibility  Irreversible changes Changes are reversible 
Example  Adaptation of the occurrence of fleshy stems performing photosynthesis in succulent plants found in deserts Increase in breathing rates of humans when they are traveling to higher altitude locations like mountains. 


Explanation:

  • Adaptation is a process in which a population of a species undergoes permanent physical and other body changes to adapt to the changing climatic conditions. 
  • Acclimatization is altogether a very temporary form of change.
  • Hence these two terms adaptation and acclimatization are different.
  • So the correct answer to this question is - Acclimatisation is a type of adaptation.
  • The rest three options, - Adaptation includes a change in the body structure as per habitat; Adaptation requires thousand of years;  Adaptation depends upon climate conditions are true for the process of adaptation.

A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given fouralternatives. Just as space permeates everything in the universe, love permeates every part, every aspect of creation. If there is one answer to the question, “How and why doesthis world exist?” the answer, in one word, is Love. Rather, the answer is Pure Love, since the word love has lost its meaning. Your very existence is an expression of pure unconditional love of the Source (you may call it Consciousness, Creator, God, Divine Self). This is the truth of your being.True love transcends both love and hatred. It is unconditional, unquestioning, boundless, unchanging love. It is overflowing love of the Source for the Source throughall of creation. True love is way beyond the personalized love that two or more individuals assert on one another. Personalized love, though apparently selfless, is rooted in desiresand conditional satisfaction. We have been brought up in a society that judges love based on conditions. We have been made to believe that we can receive love only when we fit into peoplesexpectations. If we are not good enough, we will be deprived of love. These beliefs have influenced the collective psyche of families, groups, communities, and societies since generations to such an extent that love has been reduced tofear of denial. We need to shift from the paradigm of false conditional love to the essence of pure unconditional love . The experience of true love comes with surrender of the false I, in letting go of the feeling of separateness. Without this sacrifice, it is not possible to attain divinelove. When this separate I is discarded, you embrace everything in oneness and catch a glimpse of pure love. True love can be experienced only through giving, not by demanding. People who exist in your life are not here to love you. They are here to remind you that you arethe Source of Love. By knowing that you are the Source of love, you can love yourself, instead of waiting to receive love from the world. Ask yourself, “Why do I need an agent to love myself?” Waiting for the world to love you, is like hiring an agent to love yourself! It is time for you to honor yourself as the Source of love. You have undertaken this human journey to realize and express the boundless love that you truly are. According to the passage, which of the following statement is not TRUE?
