Answer:

Option B, The neutral nature of water changes due to mixing of various salts, bases, and acids, thus changing its pH.

Explanation:

Water obtained from natural sources like underground water, sea water, rain water etc are not neutral in nature. This is so because water extracted from all these sources contains several dissolved salts/chemical components which either reduces or increases their pH.

The ground water contains lot of dissolved carbonates and bicarbonates (as it remains in contact of rocks beneath the earth) due which it becomes extremely hard and has a pH greater than 7. On the other hand rain and snow water are acidic in nature and have a pH between 5 to 6.

Thus, it is only due to the dissolved bases and acids in natural water which makes it either acidic or basic in nature.

amid [387]

Smooth muscle fibers can sustain a contraction without fatigue by allowing dephosphorylated myosin to remain attached to actin in what is called the Latch State.

Latch State- Myosin cross-bridge creation with actin is prevented by dephosphorylating its RLCs, however dephosphorylating myosin that is already attached to actin slows down its off rate, creating the so-called "latch state." In the latch state, smooth muscle maintains tension while undergoing modest rates of ATP hydrolysis.

ATP hydrolysis- When the high-energy phosphoanhydride bonds in adenosine triphosphate are split, as occurs, for example, in muscles, chemical energy that has been stored in them is released. This process is known as ATP hydrolysis.
