Protease produces what in baby food

In baby food protease brakes down the proteins and is used to pre-digest proteins during the manufacture of baby foods. 

I learnt this last week!

Hope this helps! :)

The correct option is B.

In single celled animals, contractile vacuole function in osmoregulation by regulating the quantity of water that is found in the cell, thereby regulating the osmotic pressure of the cell. Contractile vacuoles are usually found in freshwater protists.
The cells of unicellular organisms operate by osmosis, therefore, the water and the solute contents of the cell have to be balanced. Thus, if there is too much water in the cell, the contractile vacuole functions by pumping the water out of the cell. This helps to protect the cell from bursting, because if the quantity of water inside the cell is too much, the cell will swell up and burst.
