I think it would be D hope this helps
4-2 years that is how long they can live
Cytochalasin D prevents the addition of monomers at plus ends of existing filaments. When the concentration of G-actin in the cytosol is below the critical concentration, the loss of monomers at <span>minus ends</span> of existing filaments eventually results in their shortening. This occurs despite the pool of available G-actin in the cytosol.
With the exception of echinoderms, invertebrates are protostomes; chordates, echinoderms and vertebrates are deuterostomes.
