Answer:
water and oil don't mix
they form an emulsion
oil is less dense then water
Explanation:
Since there are no given answers, let's examine all pieces of information we can find here.
After mixing two liquids, Janet shook this mixture. She did it in order to enhance the rate of dissolving. After some time passed, we see that these liquids are separated into two distinct layers, meaning that water and oil do not mix (oil doesn't dissolve in water). This also means that water and oil form an emulsion - an unmixable suspension of two liquids.
Another feature we can observe is that the oil had risen to the top. Denser liquid will always fall down, meaning that oil is less dense then water.
I think the answer would be A.
Doctors examine medical history of the patient, order, perform & interpret diagnostic tests before prescribing the medicine. Mathematics required for a doctor are college algebra, trigonometry, calculus, linear algebra, statistics & probility. They use statistical models to guide diagnoses & treat. Becoming a doctor means learning everything there is to know about the human body. The human body itself is an incredible thing to study and medical students and doctors have the opportunity to further examine it with the most innovative technology.
I would say it is C, if not possibly B.
