Question

which behavior is a response that is determined by heredity?
all behaviors are determined by heredity.
hunting in packs
fighting for protection
sleeping

Explanation:

Hereditary behaviors are innate, instinctual actions not learned. "All behaviors are determined by heredity" is false, as many behaviors are learned. Hunting in packs and fighting for protection can be learned or culturally transmitted in some species. Sleeping is an innate, evolutionarily conserved behavior controlled by genetic and biological mechanisms, determined by heredity.

Answer:

sleeping
