Memory is a characteristic of adaptive immunity but not innate immunity.

During first responses to T-dependent vaccinations, memory B cells are produced.

  • They do not create antibodies, and hence do not defend, unless they are re-exposed to the antigen, which causes them to differentiate into antibody-producing plasma cells.
  • Because reactivation occurs quickly, booster reactions are distinguished by a fast rise in antibody titers that have a stronger affinity for antigens than antibodies produced during original responses.

The post germinal centre memory B cells carry Ig genes that have switched isotypes and contain somatic mutations, and they are identified in humans by the presence of the marker CD27.

  • The CD40-CD40L association helps to drive the maturation of GC B cells into long-lived memory B cells. Memory B cells have an unknown life duration.

Hence, the correct answer is option A

Which best blocks X-ray particles and can therefore be observed more closely through the use of this technology?
Vedmedyk [2.9K]

Answer:

The correct answer would be bones.

X-rays are high energy electromagnetic waves which have an ability to penetrate most of the biological tissues.

In the X-ray machine, a beam of high energy X-rays is passed through the filters and subject and then fall on the detector or photographic film to produce X-ray.

Dense tissues like bone, teeth, tumors et cetera blocks or stops most of the X-ray particles from reaching the detector or photographic film.

It forms glowing pictures on the X-ray film or photographic film.
