Question

Read the following statements.

(a) Allergy is caused due to .......... response of the immune system towards foreign antigens.
(b) Syphilis and gonorrhea are sexually transmitted diseases, which are caused by ..........
(c) Down's syndrome and Klinefelter's syndrome are the .......... diseases, which are caused by ..........
(d) Penicillin is a .......... antibiotic, which inhibits the growth of a number of bacterial pathogens by blocking the metabolic processes which build the cell wall in bacteria.

Select the correct fill-ups for any two of the above statements.

• A. (a) Exaggerated (d) Narrow-spectrum
• B. (b) Bacteria (c) (i) Congenital (ii) Chromosomal mutations
• C. (c) (i) Acute (ii) Chromosomal mutations (d) Broad-spectrum
• D. (a) Hypersensitive (b) Protozoans

Answer 1

The correct option is B (b) Bacteria (c) (i) Congenital (ii) Chromosomal mutations

1. Allergy is caused due to the allergic response of the immune system towards non-infectious substance like dust, mold or pollen.
   
2. Sexually transmitted disease by bacteria Neisseria gonorrhoeae is gonorrhea by developing warm, damp areas of a reproductive area while Treponema pallidum causes syphilis and primarily infects mouth, rectum or genitals and can be pass through infected mother to infant.
3. These are the disease caused by chromosomal mutations and are called congenital. Down's syndrome is caused by the additional copy of chromosome number 21 called trisomy of 21 while Klinefelter's syndrome is a disease occur due to the presence of an additional copy of X chromosome in males.
4. Penicillin is a broad spectrum antibiotic invented by Alexander Fleming in 1928 and used as medicine in 1942 which blocks the protein that forms the bacterial cell wall.

So the correct option is (b) bacteria (c) (1) Congenital (2) Chromosomal mutations
