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.
Answer:
A cell is in a hypertonic solution, the solution has a lower water concentration than the cell cytosol, and water moves out of the cell until both solutions are isotonic. Cells placed in a hypotonic solution will take in water across their membranes until both the external solution and the cytosol are isotonic.
To organize microtubules and provide structure for the cell, as well as work to pull chromatids apart during cell division
Answer:
They affect cancerous cells during a particular phase of cellular reproduction.
Explanation:
Cell cycle-specific drugs are chemotherapy drugs including cancer, they kill cancer when the cancer cells when they're dividing or active, unlike cell cycle non specific that kills cancer when cells when at rest mode.
Usually considered to be the most effective against tumor in cancer patients.
For example, the following are some of the antitumor antibiotics are:
Anthracyclines: Mitoxantrone and Idarubicin.
Chromomycins: Dactinomycin and Plicamycin.
Miscellaneous: Mitomycin and Bleomycin
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.
