    1. Aa hydrogen ion
    2. Bstarch
    3. Ca mitochondrion
    4. Da cell
  2. 2Compared to when a solution is basic, when a solution is acidic it has...
    1. Athe same pH
    2. Bmore free hydrogen ions
    3. Cfewer total hydrogen ions, both in free and in large molecules
    4. Dhigher pH
  3. 3The membranes that surround cells are made of many ...
    1. Atriglycerides
    2. Bnucleic acids
    3. Cstarches
    4. Dmicelles
    5. Ephospholipids
  4. 4The polarity of water...
    1. Ameans that protons are more often found by oxygen, not hydrogen
    2. Bmakes water magnetic
    3. Carises from the difference in electronegativity between oxygen and hydrogen
    4. Dallows water to make covalent bonds
    5. Eallows water to make hydrogen bonds
  5. 5The polysaccharide most likely to be a structural part of a plant is
    1. Aglycogen
    2. Bcellulose
    3. CATP
    4. Dchitin
  6. 6The fatty acid tails of phospholipids are...
    1. Ahydrophilic
    2. Bmade of steroids
    3. Chydrophobic
    4. Dfacing inside the cell
    5. Emade of glycerol
    6. Fjoined to the head by glycerol
    7. Gfacing outside the cell
  7. 7Insulin receptors are proteins in the membranes of cells. When insulin binds to the receptor it changes the shape of the receptor. The shape change activates a response in the cell. You are studying a new protein that no one has studied before. You find out your protein has the same shape as the insulin receptor. Based on this information, you would predict that your new protein has...
    1. Aa similar function to proteins with different shapes
    2. Bno function-- the protein is denatured
    3. Ca similar function to the known insulin receptors
    4. Da similar protein to the hydrophilic proteins inside the cells
  8. 8Pasteur studied germ hypothesis when the spontaneous generation hypothesis was still popular. He sterilized broth in a swan neck flask, and then waited to see if living organisms grew. With the swan neck intact, he observed that when he waited he saw...
    1. Ano bacterial growth
    2. Bbacterial growth
    3. Cdata supporting the germ hypothesis
    4. Ddata contradicting the germ hypothesis
    5. Edata supporting the spontaneous generation hypothesis
  9. 9Which type of bond holds two different water molecules to each other, or the two halves of a DNA double helix together?
    1. Anon-polar covalent bonds
    2. Bionic bonds
    3. Chydrogen bonds
    4. Ddouble covalent bonds
    5. Epolar covalent bonds
  10. 10Which two are made of monomers and held together with covalent bonds?
    1. Anucleic acids
    2. Ball acids
    3. Cwater
