Dipol-dipole Interactions are a type of intermolecular force. They are caused by polar bonds found within nonpolar molecules. When one side of a molecule has an atom that is much more electronegative than the other atoms in the molecule, the atom with the higher electronegativity pulls the electrons more closely to itself causing that end of the molecule to be
partially negative and the opposite end of the molecule to be partially positive. The oppositely charged ends of neighboring molecules attract to one another and this attraction is the

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
