which is a cause of polarity in water molecules? partial negative charge on the hydrogen atomspartial positive charge on the oxygen atomhigh electronegativity difference between oxygen and hydrogenlow electronegativity difference between oxygen and hydrogen

high electronegativity difference between oxygen and hydrogen

Explanation:

The electronegativity value of O and H are 3.5 and 2.1 respectively. The electronegativity difference of the O-H bond in H₂O is 1.4.  

Thus the O-H is a polar covalent bond. This explains the polarity in water molecules.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

i think   the answer is c hope i'm right
