Inherited trait that helps an organism survive is a(n) ____
A
Fossil
B
Adaptation
C
Ancestor
D
Natural selection
Explanation: 

Detailed explanation-1: -An adaptation is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.

Detailed explanation-2: -Definition: A biological characteristic with a heritable basis that improves reproduction and/or survival and results from evolution by natural selection.

Detailed explanation-3: -There are three types of adaptations: structural, physiological, and behavioral. Structural adaptations are how the animal’s body functions or looks on the outside. Body parts (like feet and ears) and body coverings (like fur and scales) are structural adaptations.

Detailed explanation-4: -The three basic types of adaptations, based on how the genetic changes are expressed, are structural, physiological and behavioral adaptations. Most organisms have combinations of all these types.

Detailed explanation-5: -A trait is an aspect of the whole or of a certain portion of the developmental pattern of the organism. An adaptive trait is, then, an aspect of the developmental pattern which facilitates the survival and/or reproduction of its carrier in a certain succession of environments.
