Question

Which of the following is not a type of adaptation?

Answer 1

Answer: The correct answer for the first question is- B) Mechanical.

Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.

Mechanical is not a type of adaptation as it deals with movement of objects.

The correct answer for second question is- C) Variations.

Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).

Thus, difference is in the feather color reflects variations.
