3. Among the following taxonomic categories, which one occupies the highest place in the taxonomic hierarchy as compared to the remaining three? [S.S.C. JE Electrical Exam 28.01.2020 (Shift-I)]

(a) Family
(b) Order
(c) Genus
(d) Species

Correct Answer: (b) Order

Solution:The hierarchical order of taxonomic categories is a sequence of categories in a decreasing or increasing order from kingdom to species and vice versa. The kingdom has the highest rank followed by division, class, order, family, genus, and species. Species has the lowest rank in the hierarchy.

(a) Fungi
(b) Animalia
(c) Protista
(d) Monera

Correct Answer: (d) Monera

Solution:Under the five-kingdom classification given by R.H. Whittaker, prokaryotic organisms are placed in the kingdom Monera. Kingdom Monera has unicellular prokaryotic organisms. They do not have a well-developed nucleus or advanced cell, neither do they possess any cell organelles.

6. Which of the following classifications do humans NOT fall under? [S.S.C. Online MTS (T-I) 07.07.2022 (Shift-III)]

(a) Chordata
(b) Porifera
(c) Hominidae
(d) Vertebrata

Solution:The classification that humans do NOT fall under is Porifera. Porifera is a phylum of animals that includes sponges, which are multicellular organisms that lack tissues and organs. Humans, on the other hand, belong to the phylum Chordata, subphylum Vertebrata, and family Hominidae. Chordates are animals that have a notochord, dorsal nerve cord, and pharyngeal gill slits at some point in their life cycle, while Vertebrates are chordates with a backbone or vertebral column. Hominidae is the family of great apes that includes humans, chimpanzees, gorillas, and orangutans.

8. Which of the following represents the CORRECT scheme of sub-groups at various levels in classification? [S.S.C. Online CHSL (T-I) 15.03.2018 (Shift-II)]

(a) Kingdom → Phylum → Class → Order → Family → Genus → Species
(b) Kingdom → Order → Class → Family → Genus → Species → Phylum
(c) Kingdom → Phylum → Order → Genus → Species → Class → Family
(d) Phylum → Kingdom → Class → Order → Genus → Family → Species

Correct Answer: (a) Kingdom → Phylum → Class → Order → Family → Genus → Species

Solution:The following is the order of various categories in classification from largest to smallest: Kingdom → Phylum → Class → Order → Family → Genus → Species. The smallest category of classification is species.

9. Binomial Nomenclature was founded by [S.S.C. Online CHSL (T-I) 16.01.2017 (Shift-II)]
