If a trait helps an animal blend into its surroundings and avoid predators, this trait is considered. 

What is an adaptive trait?

Natural selection acts on these inherited characteristics that vary among individuals.

What are traits?

While cells are known as the "building blocks of life", this material is known as the "blueprint of life". It is shaped like a double helix, found inside the nucleus, and it allows important characteristics to replicate and be passed on to the next generation.

What is DNA?

This happens to traits in a population when the environment changes.

What is the distribution of traits changes?

This organ system has the kidneys as its main organ, and allows the body to filter out toxins and release them from the body.

What is the excretory system?
