Answer 1

Incubation

1) The maintenance of an infant, especially one that is ill or born before the usual gestation period, in an environment of controlled temperature, humidity, and oxygen concentration in order to provide optimal conditions for growth and development.

Moulting

2) Molting, known technically as ecdysis, is literally a period of growth for insects. When one organism sheds something like hair, feathers, shells, or skin to make way for new growth it is said to be moulting. In molting, the epidermis separates from the outermost cuticle.

Hatching

Hatching means the production of young from an egg.
