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.
Answer:
If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
So that the cell itself can maintain homeostasis and balance out its necessities
Fossils are found of giraffes with short necks.
Lamarck believed the giraffes stretched their necks and passed it to their offspring
necks grew longer due to stretching.
giraffes need long necks for food and evolution provided it to them
