Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells?...
Question 26 (1 point) How is cytokinesis in plant cells different from cytokinesis in animal cells? Cytokinesis in plant cells requires formation of a cell plate; cytokinesis in animal cells requires formation of a ring of actin. Cytokinesis in plant cells occurs during G2; cytokinesis in animal cells occurs in the M phase of the cell cycle. Cytokinesis in plant cell results in one large cell with two nuclei; cytokinesis in animal cells results in two cells, each with one...

two identical malignant cancer cells with identical speeds in the blood flow, collide with each other . due to the specula adhesion of proteins on their surface, they stuck together after the collision. determine the direction of the motion of the combined masses after the collisions. of an angle (degree or radius), with respect to the positive x-xis. assume no external forces act ob the system. Hint; since speeds are identical, when v1 = v2 = v
