  • The thigh is ________ to the knee.
    Proximal
  • Relationship between solute concentration and osmotic pressure
    The greater the solute concentration, the greater the osmotic pressure.
  • Organelles that digest worn-out cell components and destroy microbes
    Lysosomes
  • Why is administering pure water intravenously dangerous?
    Pure water moves into red blood cells causing them to lyse.

    Anaphase
  • True statement about osmosis
    Water is drawn toward high concentrations of solutes.
  • Body region visible only on posterior/dorsal surface
    Popliteal
  • Cell cycle phase for protein synthesis, growth, and organelle replication
    G1 phase
  • Function of coarse and fine adjustment knobs on a microscope
    Make initial and subsequent focusing adjustments when viewing a specimen.
  • A peptide bond is found in ______ and links _______.
    Proteins; links two amino acids.

    Nonpolar covalent bond
  • Nitrogenous base that replaces thymine in RNA
    Uracil
  • Which is NOT a primary component of a typical animal cell?
    Cell wall
  • Which statement is NOT part of the cell theory?
    Cells are not the smallest living units that perform physiological functions.
