d) mimicry

?

a) habituation

Explanation:

Habituation is the adaptive learning behaviour in which the response strength is reduced when stimulus is given repeatedly. Barking and scratching of door by the dog was the response towards arrival of letter carrier. However, repeated visits of the person at the same time reduced the strength of response through the process of habituation.

a) due to a learned behavior so habituation

false

Explanation:

In cold climates, water freezes and expands as a result, breaking rocks with sheer force. The smaller rocks or sediments are washed away by erosion.

During the warm wet season, rocks expand and contract. As a result, the rocks are weakened and eventually fracture.

Note that the rate of weathering depends on the types of rock and temperature change. Rocks in tropical climates experience the highest rate of weathering because of the combination of high heat and heavy rainfall.
