(d)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Exp. None of the given sets is correctly matched.<br>Diphtheria, pneumonia and leprosy, all of these are bacterial diseases caused by Corynebacterium diphtheriae, Streptococcus pneumoniae and Mycobacterium leprae, respectively. Gonorrhea, syphilis and AIDS are sexually transmitted<br>diseases (STDs are transmitted through unprotected sexual<br>contact). AIDS is caused by Human Immunodeficiency Virus (HIV) Syphilis is caused by Treponema pallidum and gonorrhea is caused by Neisseria gonorrhoeae.<br>Color blindness and hemophilia are sex-linked diseases while, sickle-cell anemia is an autosomal disease. Polio and Japanese-B encephalitis are viral diseases and plague is a bacterial disease caused by Yersinia pestis.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Q2_Which_one_of_the_following_antimicrobial_drugs_is_suitable_for_treatment_of_both_tuberculosis_and_leprosy_1995\"><\/span>Q2.

(d)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Exp. Rifampicin is an antimicrobial drug which is suitable for both tuberculosis and leprosy. It is a semi-synthetic antibiotic produced from Streptomyces. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms, it inhibits DNA-dependent RNA polymerase activity. It thus suppresses the initiation of RNA synthesis.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Q3_The_normal_temperature_of_human_body_on_the_Kelvin_scale_is_1995\"><\/span>Q3.

Normal temperature of human body on Celsius scale = 37\u00b0C Temperature in Kelvin Temperature in degree Celsius + 273<br>37+273310 Kelvin.<br>Hence, the normal body temperature of human being on kelvin scale is 310 Kelvin.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Q4_%E2%80%9CBy_weaving_threads_of_physics_chemistry_and_biology_into_a_rich_tapestry_this_remarkable_scientist_provided_a_unifying_molecular_view_of_the_world%E2%80%A6_He_touted_the_wonderful_properties_of_vitamin-C_first_agent_against_cancer%E2%80%9D_One_of_sciences_major_figure_of_all_time_referred_to_above_is\"><\/span>Q4. &#8220;By weaving threads of physics, chemistry and biology into a rich tapestry, this remarkable scientist provided a unifying molecular view of the world\u2026.

(d)<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Exp. Viruses are capable of infecting bacteria, fungi and plants. These are sub-microscopic agents which cannot multiply on their own, so they have to invade a &#8216;host&#8217; cell and take over their machinery in order to be able to make more virus particles. As viruses have a small genome, increased virulence resulting from a chance mutation is likely. The viruses that have been detected in fungi are all thought to be double- stranded RNA.<br>Plants are susceptible to viral diseases, just like any living systems. Viruses cause many plant diseases and are responsible for huge losses in crop production and quality in all parts of the world.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Q11_Consider_the_following_statements_1_In_tropical_regions_Zika_virus_disease_is_transmitted_by_the_same_mosquito_that_transmits_dengue_2_Sexual_transmission_of_Zika_virus_disease_is_possible_Which_of_the_statements_given_above_isare_correct_2017\"><\/span>Q11.

Zika virus is caused by the Aedes aegypti mosquito that can spread dengue lever, chikungunya as well as yellow fever. It has quickly spread since the start of last year&#8217;s outbreak first in Brazil, and then through Latin America and elsewhere.Because the virus can cause birth defects, including microcephaly i.e., an abnormally small head and brain size, Sit was adviced for pregnant women to avoid travel to areas where Zika is active.
