a. What is the difference between a desirable and an undesirable change?
Answers
Answer:
Changes brought about by a person or by nature which are harmful are known as undesirable or nonagreeable changes.
Examples: Rain causing destruction by floods, souring of milk
Changes which are desired to occur (i.e. we want them to take place) are known as desirable changes.
These changes produce good results.
Examples: Rain bringing water to the crops results in germination of seeds, change of milk to curd, ripening of fruits, growth of a seedling into a plant.
Explanation:
Desirable Changes: Those changes which are desired to occur that is, we want them to take place are known as desirable changes. Examples: ripening of fruits, germination of seeds etc. Undesirable change: Those changes which we do not want to take place are called undesirable changes.
