Phalloidin is a toxin from a toadstool (mushroom). You are studying actin dynamics and the effect of phalloidin. You add G-actin
adelina 88 [10]

Answer:

Dissociation of actin subunits occurs.

Explanation:

When we add phalloidin to a solution containing G-actin, the phalloidin binds to actin filaments more tightly as compared to actin monomers which leads to a decrease in the constant rate of dissociation of actin subunits from the ends of the filament. This dissociation stabilizes the actin filaments through the prevention of filament depolymerization. So we can conclude that addition of phalloidin to actin leads to stabilizing of actin filaments.

Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.

Compare and contrast reputation and circulation in fish and humans
ANEK [815]

In fish, the heart only has one atrium and one ventricle. The oxygen-depleted blood that returns from the body enters the atrium, and then the ventricle, and is then pumped out to the gills where the blood is oxygenated, and then it continues through the rest of the body.
