Explanation:
When using chromatography, the 2 solutes in the solvent paper should have different Rf values from the base line to identify them as different compounds.
If they were to have the same speed in the solvent, they would appear as 1 dot instead of 2 separate dots, which is a false reading.
Answer:
In CONVECTION, heat energy is carried by the movement of particles of matter. In CONDUCTION, heat is transferred by particles vibrating. In RADIATION, heat is carried directly by electromagnetic waves. When a hot object touches a cool object, heat moves from the hot one to the cool one.
Explanation:
Cells need energy for various purposes
Answer:
Umami identifies foods that might contain essential amino acids.
Explanation:
You may have heard that our taste buds can recognize the four basic tastes: sweet, salty, sour and bitter. But what many still do not know is that the human taste recognizes one more taste - the "umami".
Umami is recognized by our taste buds when we eat foods that contain substances called aminoacids. The umami flavor is composed of three main substances present in various foods: glutamate, inosinate and guanylate. The ability to recognize umami taste is an evolutionary advantage of humans that represents the ability to identify foods that may contain essential aminoacids.
