Research finds that the more frequently you brush your teeth, the less likely you are to develop cavities that will need to be filled. this relationship between variables depicts a: a) negative correlation. b) positive correlation. c) bimodal set. d) quasi-experimental finding.

a) Negative correlation

Explanation:

Negative correlation is a term which basically explains a relationship between to variables in which increase in one variable causes a decrease in the other variable and vice versa. As in the given scenario, the more frequently the teeths are brushed ( variable is increasing ) the less likely is the chance to develop cavities (variable is decreasing)

Hence a)negative correlation is the right answer.

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.
