Answer:

Free radicals.

Explanation:

X-ray as an example of ionizing radiation.Like any ionizing radiation it produces free radicals  and reactive oxygen species when it interacts with biomolecules  e.g (DNA) in cells and tissues. Free radicals are atoms with unpaired  lone of electrons in  outermost shells. They are therefore  very reactive and always looking for  an unpaired lone of  electron to complete the outer shell. Thus radicals can be positive, negative or neutral in charges.

When an individual is exposed to  X-ray radiation,  hydroxyl free radicals,superoxide free radicals are produced .These radicals are damaging to DNA and cells.

E.g; the <u>hydroxyl  radicals</u> attacks the hydrogen atoms of the  deoxyribose sugar, disrupted the  ring structure and therefore the DNA structure leading to mutation.

Other radicals reaction involved addition reaction of the free radicals to the  Carbon atom in the sugar molecules ,and also addition reaction  on  the organic bases in DNA molecules, damaging the molecules.

All these belong to the second line of defense except
babunello [35]

Answer:

Option D, Gastric Juices

Explanation:

The second line of defense is a non specific defense mechanism in which no specific individual is targeted but all invaders are killed in general way. Some common mode of second line of defense are - Phagocytic cells (white blood cells), inflammatory responses, macrophage system etc. The second line of defense comes into action when the invader has surpassed the first line of defense which include either physical barrier like skin, mucous membrane, hair, cilia etc. or chemical barriers like gastric juices, saliva, Hyaluronic acid etc.

Hence, gastric juice does not belong to second line of defense.

Thus, option D is correct.
