Describe an experiment you would perform to prove that an orange contains vitamin C
Tanya [424]
To prove that a certain fruit (in this case, an orange) indeed contains a certain compound (in this case, vitamin C); then the vitamin C should be extracted and isolated from the orange and must be confirmed by molecular analysis. The extraction process involves using chemicals (i.e. 6% MPA), and procedures such as centrifugation and filtration. Then the extract is stored and subjected to high-performance liquid analysis (HPLC) to measure the vitamin C content.

Which of the following properties of water help to explain why icebergs float in the ocean?
eduard
I think the best answer from the choices would be the first option. Icebergs float in the ocean since i<span>cebergs are composed of freshwater and freshwater is less dense then salt water. The ocean contains salts which contributes to its density which most likely would be higher with that of an iceberg.</span>

remember to imagine that blood in the heart is color-coded according to its oxygenation status. What color of blood would you ex
Vinvika [58]

Answer:

Red blood.

Explanation:

Red blood is for oxygenated blood, while blue blood is for deoxygenated blood.

The blood in Isabelle's left ventricle would be red, in other words, oxygenated. The left ventricle has oxygenated blood because this blood was first in the right ventricle. Then, it went to the pulmonary arteries, which led the blood to the capillaries close to the alveoli in the lungs. In this area, the deoxygenated blood dropped the CO₂ and took O₂ becoming oxygenated blood. Now, this blood is color-coded red and will go to the pulmonary venules, then to the pulmonary vein, and from there, it will go to the left atrium. Lastly, it will go to the left ventricle to start the systemic circulation, which is the one that distributes the oxygenated blood in the body.
