Plants perform cytokinesis differently than animals because
a. plant cytokinesis takes place during interphase but animal cytokinesis takes place in cell division.
b. plant chromosomes are more difficult to separate than animal chromosomes.
c. the rigid cell wall of the plant cell prevents the plasma membrane from pinching inward like it does in animal cells.
d. the centrosomes of plants do not replicate prior to cell division.

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone
