1_________ means that growth is not equal in all directions?
- Aanisotropic
- Bproportional
- Cadaptable

2why cells can't be very large
- Abecause they would have more copies of genes, causing an imbalance
- Bbecause more mRNA would be needed but the number of copies of genes would be the same

5CDK levels...
- Aremain more or less the same throughout the cell cycle
- Bdepends on the level of cyclins present in every phase of the cell cycle

11the direction of mitosis is controlled by
- Athe cell polarity
- Bthe planar polarity
- Cthe North-South ends of a cell
- Dthe neural tube formation

12how does spindle orientation take place?
- Athe trapping complexes bind to the actin filaments involved in mitosis
- Bthe trapping complexes + the cell polarity complexes bind to the microtubules involved in mitosis
- Cthe cell polarity complexes determine the orientation of the microtubules in mitosis
- Dthe cell polarity complexes determine the orientation of the actin filaments in mitosis as they bind to the trapping complexes
