At a high elevation, there is little chance of... a) flooding b)lack of oxygen c) getting dizzy

A. flooding

Explanation:

At high elevations air becomes thinner so a person may not be receiving enough oxygen which can cause dizziness. Flooding typically happens at sea level.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

the answer is c.the valence of the atoms combine .
