Consider the following statements regarding adaptation in plants and ...
  • Adaptation does not occur over a short period of time. It is related to the plants and animals adapting themselves to the changes having occurred over millions of years.
  • If we live in the plains and suddenly go to high mountain regions, we may experience difficulty in breathing and doing physical exercise for some days. We need to breathe faster when we are on high mountains.
  • After some days, our body adjusts to the changed conditions on the high mountain. Such small changes that take place in the body of a single organism over short periods, to overcome small problems due to changes in the surroundings, are called acclimatisation.

Consider the following statements regarding adaptation in plants and ...
Explanation:

Statement 1: The presence of specific features or certain habits, which enable a plant or an animal to live in its surroundings, is called adaptation.

This statement is correct. Adaptation refers to the process by which organisms develop specific features or behaviors that enable them to survive and reproduce in their particular environment. These adaptations can be physical, physiological, or behavioral in nature. For example, plants growing in arid regions may have adaptations like reduced leaf surface area, deep roots, or succulent stems to conserve water. Similarly, animals living in cold climates may have adaptations like thick fur or blubber to insulate their bodies.

Statement 2: A person who lives in the plains, breathes rapidly in a hilly region, but becomes normal after a few days. This is an example of adaptation.

This statement is incorrect. The described scenario is not an example of adaptation. The person's rapid breathing in a hilly region is a physiological response to the lower oxygen levels at higher altitudes. This response is not a result of any long-term or heritable change in the person's respiratory system. The person's breathing rate returns to normal after a few days because their body adjusts to the lower oxygen levels by producing more red blood cells and increasing the efficiency of oxygen uptake.

So, only Statement 1 is correct.

To summarize:
- Adaptation refers to the presence of specific features or certain habits that enable organisms to live in their surroundings.
- Adaptations can be physical, physiological, or behavioral in nature.
- The described scenario in Statement 2 is not an example of adaptation, but rather a temporary physiological response to lower oxygen levels at higher altitudes.
