If extracellular solution is isotonic, which direction will water move?

• Into cell

• Out of cell

• Both into and out of cell

• No water movement

Water moves from

• High water potential to low water potential

• Low water potential to high water potential

The higher the solute concentration…

• the higher the water potential

• the lower the water potential

Pressure potential = 0.2 MPa and solute potential = - 0.6 MPa…

• Water Potential = -0.8MPa

• Water Potential = -0.4 MPa

• Water Potential = 0.4 MPa

• Water Potential = 0.8 MPa

Which direction is DNA synthesized in DNA replication?

• 3' -> 5’

• 5' -> 3’

• C terminus to N terminus

• N terminus to C terminus

What enzyme is responsible for making the new DNA strand?

• DNA polymerase

• Helicase

• Ligase

• Primase
