Question 1
1 / -0

The correct sequence of taxa is

A
Class$$\rightarrow$$order$$\rightarrow$$ family$$\rightarrow$$ species$$\rightarrow$$ genus

B
Class$$\rightarrow$$ family$$\rightarrow$$ order$$\rightarrow$$species$$\rightarrow$$genus

C
Phylum$$\rightarrow$$order$$\rightarrow$$class$$\rightarrow$$species$$\rightarrow$$genus

D
Phylum$$\rightarrow$$class$$\rightarrow$$order$$\rightarrow$$ genus$$\rightarrow$$species

Solution

Taxon or Taxa refers to a one or more units of populations of organisms as per their biological classification. These units are given ranks and based on certain characteristic features the organisms are placed under different ranks of taxa. As per the biological classification, the correct hierarchical sequence of taxa is phylum- class- order- genus and species.
Question 2
1 / -0

What is the scientific name of Asian tiger mosquito?

A
Aedes aegypti

B
Aedes albopictus

C
Aedes taeniorhynchus

D
Aedes albolineatus

Solution

The Asian tiger mosquito (Aedes albopictus) is a small black and white mosquito, about 1/4-inch long. It has black and white striped legs, and small black and white striped body. It is native to tropical and sub-tropical South-east asia. Hence option B is correct.
Question 3
1 / -0

A taxon is observed. Himgiri variety which is resistant to hill bunt disease belongs to this taxon. In this taxon, pollen grains lose viability within 30 minutes of their release from anthers. The taxon belongs to the order:

A
Sapindales

B
Polemoniales

C
Rosales

D
Poales
Solution
- The Himgiri is the resistant variety of Wheat plant which is resistant to the hill bunt disease.
- The pollen grains of this plant are known to lose their viability within 30 minutes of their release.
- The wheat plant belongs to the order Poales and so the taxon of this plant is considered as Poales.
Thus, the correct answer is option D.
Question 4
1 / -0

Which of the following best defines species?

A
A group of organisms that occupy the same place.

B
A population that works together to defend itself from predators.

C
A group of organisms that can mate with each other.

D
A population that preys on other populations.

E
A population in which all members benefit from the association in some way.

Solution

Species is a group of individuals that can potentially interbreed to produce fertile offspring. Splitting of existing species into daughter species or transformation of existing species into a new one without formation of any lineage species is termed as speciation.
Therefore, the correct answer is option C.
Question 5
1 / -0

A group of organisms belonging to same order in classification also come under same

A
Genus

B
Class

C
Species

D
Family

E
Race

Solution

In the classification system, if the members belong to the same order then they also belong to the same class because in biological classification, rank is the relative level of a group of organisms (a taxon) in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, order, class, phylum, kingdom, domain, etc. Class in the higher level than the order which consists group of different orders. The order consists one or more than one similar families e.g., family felidae are included in the order Carnivora. The class consists one or more than one orders e.g., class Mammalia includes all mammals which are bats, rodents, kangaroos, whales, great apes and man.
Question 6
1 / -0

Which of the following taxon includes more similar members than the members of a class?

A
An order

B
A phylum

C
A genus

D
A species

E
A family

Solution

Th hierarchical system of classification allows the distribution of the organisms in different groups on the basis of their similarities and differences. The taxon is kingdom, phylum, class, order, family, genus, and species. Here, the taxa phylum comes before class which describes that there are more number of similar members in the phylum compared to class.
Thus, the correct answer is option B.
Question 7
1 / -0

Which group shares most common characters with each other?

A
Members of the same kingdom

B
Members of the same genus

C
Members of the same phylum

D
Members of the same class

E
Members of the same family

Solution

The seven essential ranks of taxa in the descending order are the kingdom, division/phylum, class, order, family, genus and species. The number of shared characters decrease as one moves towards the higher ranks. Therefore, among the given options, members of the genus will exhibit most common characters with each other which will go on decreasing when we move towards the kingdom.
Thus, the correct answer is option B.
Question 8
1 / -0

Nomenclature is governed by certain universal rules. Which one of the following is contrary to the rules of nomenclature?

A
Biological names can be written in any language.

B
The first word in a biological name represents the genus name and the second is a specific epithet.

C
The names are written in Latin and are italicised.

D
When written by hand, the names are to be underlined.
Solution
Correct option: A
Explanation:
According to binomial nomenclature, each organism has two names generic and species name. Following are the major guidelines for the scientific naming-
Every scientific name should have words either in Latin or be Latinized.
The first word denotes the name of the genus and the second to the name of the species.
The name of the genus should begin with a capital letter and the name of the species begin with a small letter.
Both the names should be printed in italics or otherwise underlined separately when written.
Hence, Biological names can be written in any language is the correct answer.
Question 9
1 / -0

Choose the wrong statement with reference to subspecies.

A
They do not interbreed with individual of other subspecies.

B
They are new species in the making.

C
Geographically isolated population of a species.

D
They show minor variations from parent population.

Solution

Subspecies are a rank of classification lower than a species. These sub-species are capable of interbreeding and producing fertile offsprings, but they do not usually interbreed in nature due to geographic isolation, sexual reproduction or other factors.
Thus, the correct answer is option (A).
Question 10
1 / -0

Which of the following is the correct date of publication of the book entitled Species Plantarum authored by Carolus Linnaeus? This date is starting point date for modern plant nomenclature.

A
1st May 1753

B
1st January 1935

C
1st January 1856

D
1st May 1856

Solution

The 'Species Plantarum' is a book by Carl Linnaeus, originally published on 1st May 1753 by Laurentius Salvius in Stockholm, in two volumes. It lists every species of plant.
Thus, the correct answer is option (A),
