Answer 1

The specific characteristic that an organism can pass to its off spring can be called a trait.

The trait that helps an organism survive and reproduce is an adaptation (for example, an adaptation to the cold)

And, finally: the process by which individuals that are better adapted to their environment are most likely to survive and reproduce is called natural selection!
