Answer:
An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
Explanation:
There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

I really just want to say B because they just suppress the immune system, but they are used to treat autoimmune diseases, but the drug itself doesn't replace anything
Around 14% of women have .................................... one year after giving birth.
This type of penetration disorder is called dyspareunia. This type of disorder usually has a physical cause, such as injury to the vagina during child birth. Psychological factors such as over anxiety and relationship problems may also cause this type of disorder.
