An atom will usually form either an ionic bond or covalent bond with another atom but not both.

Ionic bonds are the kind of bonds that result when one atom transfers or gives up electrons and another atom receives them and adds them to its own energy shells.

An example is sodium metal and chlorine gas. Sodium gives up two of its electrons and Chlorine receives them and the two elements form an ionic bond to create sodium chloride, a new compound.

Covalent bonds are the kind of bonds formed when two atoms decide to share electrons. No atom gives up any electrons and neither does the other atom receive any. An example is water. An oxygen atom shares two of its electrons with two hydrogen atoms to form a molecule of water (H2O).

accumulations of genetic mutations over time.

Genetic and epigenetic changes compound over time to cause cancer. While aging and chronic inflammation are the major causes of epigenetic changes, carcinogenic substances, UV radiation, and other conditions can also cause genetic changes. Our prior exposure levels and life history are reflected in the accumulation and patterns of changes in normal cells. The majority of accumulated changes are regarded as passengers, although they are linked to cancer drivers as they accumulate. Although only hypothesized for genetic changes, this has been demonstrated for aberrant DNA methylation. However, modern technology has made it possible to assess uncommon point mutations, and research has revealed that the rates of their accumulation do actually correspond with cancer risk.

strojnjashka [21]

Answer:

e) a drive

Explanation:

We felt thirsty when we have fluid imbalance in our body either we have less water or we have more concentration of osmolytes such as sodium in blood. The brain detect the change produce the effect for the intake of water.

However thirst is a vital primordial emotion that motivates us for fluid intake. So the emotion produces a drive to quench it.
Some recent studies refers it as basic instinct to drink water.
