Tissue growth by cells dividiging in response to a normal demand, such as callus formation on our hands when we work hard, is

hyperplasia

Explanation:

Cellular adaptation refers to the ability of the cell to change in order to respond to any changes that occur in the environment. Oftentimes, the changes are adverse. The adaptations can be seen in different situations such as hypertrophy, atrophy, hyperplasia, metaplasia or dysplasia.

We will focus on hyperplasia.

Hyperplasia- this refers to an increase in tissue size as a result of an increase in the number of cells. There are two types of hyperplasia, the physiological and the pathological. Callus formation is a physiological type of hyperplasia because the growth occurs only in the epithelial cells and the growth is not abnormal. The callus is formed because it tries to protect the injured site. An abnormal growth of cells signals a pathological hyperplasia.
