What's the difference between bulb and bulk?

Bulb


Definition:

  • (n.) A spheroidal body growing from a plant either above or below the ground (usually below), which is strictly a bud, consisting of a cluster of partially developed leaves, and producing, as it grows, a stem above, and roots below, as in the onion, tulip, etc. It differs from a corm in not being solid.
  • (n.) A name given to some parts that resemble in shape certain bulbous roots; as, the bulb of the aorta.
  • (n.) An expansion or protuberance on a stem or tube, as the bulb of a thermometer, which may be of any form, as spherical, cylindrical, curved, etc.
  • (v. i.) To take the shape of a bulb; to swell.

Bulk

  • (4) Chromatographic separation revealed that the bulk (85%) of the mitogenic activity in SSV-transformed NRK cells was not due to p28v-sis but rather two distinct endothelial cell growth factors that eluted off heparin-Sepharose between 1 and 2 M NaCl.
  • (5) The remainder of the plasmid appeared to be associated with five positioned nucleosomes and two nonnucleosomal, partially protected regions on the bulk of the molecules.
  • (6) The fact that proteolytic activity could be detected within 2 days at 7 degrees C is significant, since bulk cooled milk is normally held for 3 to 4 days at temperatures between 4 and 7 degrees C at farms or factories prior to processing.
