Opposite charges of polar molecules can interact to form hydrogen bonds. The hydrogen bond in polar molecules occurs only in compounds that have hydrogen bonded to N, O, or F. <span>These very highly electronegative</span><span> </span><span>elements</span><span> create a partial positive charge on the hydrogen. </span><span>The H atom is attracted to the partial negative charge on an N, O, or F atom in another molecule.</span>
However, the hydrogen bond is a strong intermolecular bond.

A person's environment can influence their personal health such as<u> exposure to certain chemicals increasing the risk of cancer.</u>
<u></u>
Explanation:
The environment has a significant influence on the expression of the gentoype of an organism to cause its phenotype.
Living in a toxic environment will also cause increased risk to diseases. This is because there is the presence of mutagens in a toxic environment. Mutagens, like lead, arsenic, ultraviolet rays, and etc, cause an increased risk of mutations in a population. Increased mutation rates means increased chances of developing cancer in the population.
