Explain how the hydrophobic and hydrophilic properties of phospholipids help maintain the structure of the cell membrane.
What is hydrophilic heads attract water so therefore face outwards (toward the surfaces of the membrane) and the hydrophobic tails are not attracted to water so point inwards

Explain what the chromosomes do during the phases of mitosis (in order)
What is (Interphase: chromosomes duplicate and coil up) Prophase: chromosomes are copied and have formed chromatids; nuclear membrane dissapears, spindle fibers form, nuclear membrane breaks down Metaphase: chromosomes line up at the equator; spindle fibers are attached to chromosomes at the centromere Anaphase: sister chromatids get pulled to opposite polls of the cell by the spindle fibers Telophase: separated chromosomes are now on opposite polls of the cell and uncoil; nuclear membrane reforms, spindle fibers dissapper, cytokinesis occurs.
