Innate: keratinized epithelium
stratified squamous epithelium hypodermal areolar connective tissue antigen presenting cells major histocompatibility complexes complement (antibody -dependent pathway )
Innate or non-specific response is the first defense against invaders. Components of this response include physical (e.g. skin . mucosa) and chemical barriers against pathogens and cells such as Natural Killer cells, macrophages, neutrophils, dendritic cells, mast cells, basophils, eosinophils. Innate response reacts immediately.
Adaptive: immunoglobulin plasma cells agglutinin
helper t cells memory t cells cytotoxic t cells cd4+cells
t lymphocytes
Adaptive immune response or specific response is specific to the pathogen presented and mediated by lymphocytes, B and T cells. Adaptive immune response creates immunological memory after the first, initial l response to a specific pathogen which leads to enhanced response.
That's because they are in the same climate zone. The earth's climate zones change going from the north pole to the equator, and then from the equator to Antarctica, like a mirror image. The two are found in the same zones on the opposite hemispheres.
Answer:
Option B
Explanation:
The series of events mentioned in this description are as follows -
a) In 1850, ash layer deposits over the layer of red clay
b) In 1902, layer of silt from tsunami covers the ash
Now pot is found in between ash and red clay layer
While coin is found in between ash and silt.
Thus, it is clear that pot was first buried between the ash and red clay layer. While coin was buried in 1902 above the ash layer but beneath the silt layer.
Hence, option B is correct
