<span>Chicks hatching from eggs is an innate behavior. Innate
behavioral adaptations are the result of millions of years of evolution. This
type of behavior is already "hard-wired" in the nervous system of
organisms and is usually inflexible. This is where a certain given stimulus triggers

The thoracic cavity is the anterior ventral body cavity found within the rib cage in the torso. It houses the primary organs of the cardiovascular and respiratory systems, such as the heart and lungs, but also includes organs from other systems, such as the esophagus and the thymus gland.
They must occur in the DNA, which is in each cells nucleus. More specifically the nucleolus of the cell. A mutation occurs in an allele, where a base triplet (or a codon) gets transcribed incorrectly.
