Alright, so mass is a property of a physical body. During physical changes, such as acceleration, force, etc, the mass stays the same since we are not affecting its physical shape, just where it is physics wise. So yeah mass is conserved during a physical change.
(This is very confusing I'm bad at explaining things sorry)
Speed. Reaction. Function. Alter.
Answer:
The scientific method is a process for experimentation that is used to explore observations and answer questions.
Sour milk contains less lactose than the fresh milk, as the sour milk gets converted to lactic acid and bacteria which enhances the digestion process. One important reason is that proteins take more time in getting digest than other nutrients. We know that fresh milk has a large amount of lactose.
Explanation:
The lactic acid bacteria have many benefits. They improve lactose digestion in the stomach. The lactase activity of the bacteria performs the task of digesting lactose in the product once it reaches the intestine thus fuelling the process of digestion in case of sour milk.
In fresh milk, the casein protein in contact with milk forms curdles which are difficult to digest.
We grow the vegetation and we get our oxygen from plants and vegetation.
