2) Young that are born in an undeveloped state and require care and feeding from their parents
3) Young that are born with fully developed physical and behavioral traits
4) Young that are born with a mix of developed and undeveloped traits

Answer 1

Altricial young are those that are born in an undeveloped state and require extensive care from their parents, including feeding and protection.

Step-by-step explanation:

The description that best fits the definition of altricial young is: 2) Young that are born in an undeveloped state and require care and feeding from their parents. Altricial young are dependent on their parents for survival, as they are born helpless, often blind and without feathers in the case of birds. Parental care for altricial young usually includes making a nest, feeding them, and protecting them from predators, which increases their chances of survival. This contrasts with precocial young, which are more developed, able to feed themselves, and require minimal parental care after birth.
