Answer:
The correct answer is option B.
Explanation:
FRAP or Fluorescence Recovery After Photobleaching refers to a method of finding the kinetics of diffusion in living cells, generally with the assistance of fluorescence microscopy. The method comprises the labeling of a particular cell constituent with a fluorescent molecule, imaging that cell, photobleach a small section of the cell, then image the recovery of fluorescence with time.
In the given question, as the fluorescence has recovered back to the bleached region. The scientist can come to the conclusion that the membrane of the cell and the peripheral membrane proteins do not always belong together.
Students hypothesized that adding lactose to a sixth test tube would produce the greatest amount of carbon dioxide.
This is because lactose is a sugar molecule that is the food source for the yeast.
Fermentation is a metabolic pathway that occurs anaerobically, meaning in the absence of oxygen (O2). It includes the process of glycolysis with some extra reactions which make alcohol.
