Most parallelograms do not have any lines of symmetry. The only parallelograms that can have lines of symmetry are squares, rectangles, and rhombuses.
I don't think a human foot has any lines of symmetry. I don't know about other species.
A circle has an infinite number of lines of symmetry, corresponding to any of its diameter lines, to any arbitrary level of division (degrees, minutes, seconds).

A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
A rectangle has 2 lines of symmetry whereas a square has 4 lines of symmetry
Yes, there are infinite lines of symmetry in a circle.

An arrow typically exhibits reflectional symmetry, also known as mirror symmetry. This means that if you were to draw a line down the center of the arrow, the two halves would be mirror images of each other. Arrows do not usually have rotational symmetry, as rotating them around a point would not result in the same shape.
Most parallelograms do not have any lines of symmetry. The only parallelograms that can have lines of symmetry are squares, rectangles, and rhombuses.
12 * * * * * A dodecagon need not have any lines of symmetry. It can have 1, 2, 4 or 12 lines of symmetry.
A square by definition has lines of symmetry. Therefore a square cannot be drawn without any lines of symmetry.
