How does the washing of hands prevent a societal problem? it keeps water supplies clean. it treat inherited disease. it protect the environment. it reduces the spread of disease.

The Answer is D. It reduces the spread of disease/sickness.

We can rule A out since it has nothing to do with water pollution or keeping it clean. We can also rule out B since it can't treat diseases. Now we are left with C and D. C doesn't make sense since washing your hands isn't helping the environment, it is helping you. D makes sense since it helps people get sick and catch diseases that can be spread through viruses and germs which are located on the hands.

Hope I helped! ;)

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
