Is bacteria alive? What can bacteria do?

yes, bacteria is alive because it can basically generate energy and including molecules to keep itself alive. There are sone bacteria that can help to digest food, destroy disease-causing cells, also giving the body its needed vitamins.

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.
