What are Smooth muscles?
Because it lacks sarcomeres and as a result, striations, smooth muscle is an involuntary non-striated muscle (bands or stripes). Its two subgroups are single-unit smooth muscle and multi-unit smooth muscle. A syncytium is the collective contraction of the sheet or bundle of smooth muscle cells that make up a single-unit muscle.
Smooth muscle makes up the walls of hollow organs including the stomach, intestines, bladder, and uterus as well as the blood and lymphatic vessels, as well as the tracts of the respiratory, urinary, and reproductive systems. The ciliary muscle, a type of smooth muscle present in the eyes, changes the shape of the lens by dilation and contraction of the iris.

Answer with explanation:
a. 3 sodium ions will move from inside to outside while 2 potassium ion will mover from outside to inside. This movement occur to maintain the gradient across the membrane
b. due to ion movement the concentration of sodium ions become higher outside the cell while the concentration of potassium ion will decrease
c. Due to 3 sodium ion movement outer change became positive (+).
d. due to ion movement the concentration of sodium ions become lower inside the cell while the concentration of potassium ion will increase inside
e. this change results in decrease in charge therefore charge inside the membrane becomes negative (-). See Solved Figure Attachment.
