Answer:

The correct answer is option D.

Explanation:

The outer surface of body defenses is nonspecific, which means they do not attack specific pathogens. Skin is the very first immune system against nonspecific pathogens. Other than mucous membranes also act as a barrier to pathogens and produce chemical defenses.

Saliva also provides a non-specific external response as it contains mucus, antibacterial compounds and various enzymes to target bacteria and other pathogens.

Thus, the correct answer is option D.

This has to do with blind spots: What parts of the eye are involved with this inability to see? How do these eye parts function?
Slav-nsk [51]

Answer:

  • Blindspot
  • It has a vital role. It is the only way out of the optic nerve. By this hole optic nerve exits from the eye and goes towards the brain.
  • It can be proved by a simple experiment. A paper sheet is taken. Then a cross and a circle are drawn side by side on that paper. Then we will focus on the cross. Then by closing one eye and by bringing the paper slowly towards our face, the circle will be disappeared at a certain point.        

Explanation:  

The blind spot is a region on the retina where ganglion cells connect with the optic nerve, and the optic nerve and blood vessels leave the eyeball. There are no receptors in this area so nothing can be translated into vision. That's why the blind spot is unable to see things.

Both coal and diamonds are forms of elemental carbon. Coal is brittle while diamonds are considered to be the hardest Of all sub
Art [367]

arbon, as with many elements, can arrange its atoms into several different geometries, or "allotropes." In pure diamond, every carbon atom is covalently bonded to exactly 4 other carbon atoms in a very specific and energetically favorable geometry. The diamond cannot be broken or scratched unless many covalent bonds are broken, which is difficult to do. In another common allotrope, graphite, every carbon atom is covalently bonded to only 3 other carbon atoms, and the atoms are arranged in sheets that are not covalently bonded to each other. The sheets can be broken apart easily, ultimately meaning that graphite can be easily scratched. Coal is composed of particles of different allotropes of carbon, and some "amorphous carbon," which has no defined geometry in its atomic structure. Without a continuous network of covalent bonds, coal is easily scratched (i.e. it is not hard).
