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.
The main responsible for the delay among the atrial and
ventricular contractions is the action potential conduction velocity of the AV
node cells. If the atria and ventricles contract simultaneously, atria cannot
give any help in filling the ventricles, which is needed, especially in those
with stiff ventricles as in the elderly. Hence atria have to contract first and
then the ventricles.
