Question

Which of the following is not a type of adaptation?

A. Structural
B. Mechanical
C. Behavioral
D. Functional

Slight differences in inherited traits, such as feather color in birds, are called
A. adaptations.
B. differential traits.
C. variations.
D. mutations.

Answer 1

The type of adaptation not recognized in biology is 'Mechanical', and slight differences in inherited traits are known as 'Variations'.

Step-by-step explanation:

The type of adaptation that is not listed among recognized biological categories is Mechanical. In biology, the recognized types of adaptations are Structural, Behavioral, and Functional. Thus, the correct answer to the first part of the question is 'B. Mechanical'.

Slight differences in inherited traits, such as feather color in birds, are called Variations. These variations can sometimes lead to adaptations if they provide some advantage in survival or reproduction within a particular environment. Consequently, the correct answer to the second part of the question is 'C. Variations'.

An adaptation is a heritable trait that aids the survival and reproduction of an organism in its present environment. The types of adaptations include structural, mechanical, behavioral, and functional adaptations. Therefore, the correct answer is D. Functional.

Slight differences in inherited traits, such as feather color in birds, are called adaptations.

Answer 2

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.
