Scientists are studying compounds in a newly discovered rainforest plant. The plant produces an unusual substance that local people say acts as an anesthetic. If another scientist tests the substance using iodine, the scientist testing for carbohydrates.
The existence of carbohydrates in leaves can be sampled by the Iodine test. When chlorophyll is removed from the leaf by boiling it in alcohol and then placing two drops of iodine solution it turns blue in color which indicates the presence of starch.
The iodine test is a test that is utilized to test for the existence of starch. The mixture of starch and iodine produces an extremely blue-black color.

Answer & explanation:
This acidity in our stomach is advantageous because it kills most bacteria and creates the ideal environment for the enzymes pepsin and gastric lipase to digest food.
The pH corresponds to the hydrogen potential of a solution, this potential can be classified as acid, basic or neutral.
Respuesta y explicación:
Esta acidez en nuestro estómago es ventajosa porque mata a la mayoría de las bacterias y crea el ambiente ideal para que las enzimas pepsina y lipasa gástrica digieran los alimentos.
El pH corresponde al potencial de hidrógeno de una solución, este potencial se puede clasificar como ácido, básico o neutro.

Answer:
We mean that a cell changes to another type of cell.
Explanation:
<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.
Then, a differentiated cell is a cell that had gone under the previously described process.
