What is the main function of the muscular system is to allow the of the body

The muscular system is composed of specialized cells called muscle fibers.

Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement.

Nearly all movement in the body is the result of muscle contraction.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
