A
Order, class, family

B
Class, order, family

C
Family, class, order

D
Order, family, class

Solution

Taxonomic hierarchy is a framework by which we arrange taxonomic groups into definite order from higher to lower category. The sequence of taxonomic categories according to taxonomic hierarchy is as follows - kingdom, phylum, class, order, family, genus, species.
So, the correct answer is option B.
Question 2
1 / -0

'Systema Naturae' was written by

A
Lamarck

B
Cuvier

C
Aristotle

D
Linnaeus

A
E. Haeckel

B
John Ray

C
G.L Cuvier

D
Carolus Linnaeus

Solution

In 1866, Ernst Haeckel coined the term 'phylum' for the classification of animals. It is the category below the Kingdom and is made up of various classes sharing common features. The same category is called the 'division' for plant classification and this term was given by August W. Eichler in 1883.
A. Ernst Haeckel coined the term 'phylum'
B. John Ray established the category of 'species'
C. G.L. Cuvier was the proponent of catastrophism in geology in the early 19th century.
D. Carolus Linnaeus gave binomial nomenclature.
Hence, the correct answer is 'E. Haeckel'
Question 4
1 / -0

The term 'biosystematics' was coined by

A
Gaspard Bauhin

B
Camp and Gilly

C
Karl Prantl

D
Robert Brown

Solution

Biosystematics is the branch of biology which deals with the evolutionary relationships and is used for the classification of the organisms on the basis of their history, phylogenetic studies, anatomy, physiology, etc, in order to place them in a specific hierarchical rank. The term biosystematics was coined by Camp and Gilly in the year 1943. Thus, the correct answer is option B.
Question 5
1 / -0

Interbreeding natural population of animals are referred to as belonging to the same

A
Family

B
Species

C
Genus

D
Variety

Solution

A species is the group of individuals having similar morphological and reproductive features. This is the lowest rank in the hierarchical classification system. They can interbreed and reproduce. These are the further classification of the organisms in the same genus which has similar characters.
Thus, the correct answer is option B.
Question 6
1 / -0

Match the following and choose the correct combination from options given.

Column I
Column II
A Wheat 1 Primates
B Mango 2 Diptera
C Housefly 3 Sapindales
D Man 4 Poales

A
A- 1, B- 2, C- 4, D- 3

B
A- 4, B- 3, C- 2, D- 1

C
A- 2, B- 4, C- 1, D- 3

Solution
The column I has the name and the column II contains respective order name.
Wheat (Triticum species) belongs to order poales, Family: Poaceae Class: Monocotyledonae. Wheat is believed to have originated in southwestern Asia and mostly hexaploid. It is a rich source of lysine.
Mangoes are juicy stone fruit (drupe) from numerous species of tropical trees belonging to the flowering plant genus Mangifera and order Sapindales, cultivated mostly for their edible fruits.
Housefly (Musa domestica) belongs to order Diptera. It is evolved in the Cenozoic era, possibly in the Middle East, and has spread all over the world. It acts as a transmitting agent for spreading of disease.
Man belongs to order Primates. Primates are the group which contains all lemurs, ape and monkeys including humans. They are characterised by large brain capacity, stereoscopic vision and dominant sensory system. Thus, the correct answer is option B.
Thus, the correct answer is option B.
Question 7
1 / -0

International Code of Botanical Nomenclature is applicable to

A
Plants

B
Animals

C
Species

D
All of the above

Solution

International Code of Botanical Nomenclature is applicable to algae, fungi, and plants. It is a set of rule which helps in the proper nomenclature of algae, fungi and plants. It provides a formal botanical names to these organism. It provides the rule to frame the botanical name of the organism. A botanical name consists of two names, the genus and the specific epithet or species name. According to ICBN rule, the genus name starts with capital letter while the species name is written in small letters. Both the names are written in italics and are underlined separately.
So, the correct answer is option A.
Question 8
1 / -0

An attribute found in plants but not animals is

A
Metabolism

B
Sexual reproduction

C
Autotrophy

D
Asexual reproduction

Solution

Autotrophic organisms synthesise their own food. Photoautotrophs are green plants which synthesise their own food using the energy of sunlight. Plant fix atmospheric carbon in presence of sunlight and convert them into glucose and energy in the form of ATP. While animals can not synthesise their food and depend on plants and other animals for their food i.e heterotrophs.
Thus, the correct answer is option C.
Question 9
1 / -0

Oryza sativa is the binomial name of the rice plant, the sativa stands for

A
Specific name

B
Specific epithet

C
Genus name

D
Specific nomenclature

Solution

In the binomial system of classification, every species is given in a two-part name. The first part represents a genus and the second part is a specific epithet. Together these two are called species. E.g., Oryza sativa where Oryza is genus and sativa is specific epithet and these two together represents species.
So, the correct answer is option B.
Question 10
1 / -0

Keystone species are

A
Species belonging to same period.

B
Species that determine structure of biotic community.

C
Species reproducing sexually.

D
Species recorded only in the fossil state.

Solution

A keystone species is a species, that plays a critical role in maintaining the structure of an ecological community and whose impact on the community is greater than would be expected based on its relative abundance or total biomass.
So, answer is- 'Species that determine structure of biotic community'.
