Question

what changes occur when milk changes into curd?​

Answer 1

Answer:

Area Of Sector

It consists of a region bounded by two radii and an arc lying between the radii. The area of a sector is a fraction of the area of the circle. This area is proportional to the central angle. In other words, the bigger the central angle, the larger is the area of the sector.

Answer 2

Answer:-

When the milk is converted into curd due to the action of bacteria, lactic acid is formed which is more acidic in nature.

Explanation:-

The process by which the milk is converted into curd is called fermentation. * Curd contains bacteria called 'lactobacillus'. When one spoon of curd is added to the milk (the precursor curd), the lactobacillus multiplies itself inside the milk.
