Weekly Quiz Competition

Question 1
1 / -0

The species (man, housefly, mango, wheat, dog, cat, lion, tiger, potato, brinjal, makoi and leopard) given here belong to how many different families?

A
4

B
7

C
5

D
6

Solution

The families of species given are:
1. Felidae(cat,lion,tiger and leopard)
2 .Homonidae(man)
3. Muscidae(housefly)
4. Anacardiaceae(mango)
5 .Poaceae(wheat)
6. Solanaceae(potato,brinjal,makoi)
7 .Canidae(dog)

So the correct option is '7'.
Question 2
1 / -0

How many obligate taxonomic categories are common between man and housefly?

A
A) One

B
B) Two

C
C) Three

D
D) Four
Solution
Scientific classification of :
Man: Kingdom Animalia > Phylum Chordata > Class Mammalia > Order Primates > Family Hominidae > Genus Homo > Species Sapiens.
Housefly: Kingdom Animalia > Phylum Arthropoda > Class Insecta > Order Diptera > Family Muscidae > Genus Musca > Species Domestica
So, Kingdom Animalia is a common taxonomic category between the two given organisms.
So, the correct answer is 'One'.
Question 3
1 / -0

Consider the following statements and select the correct set of options -

A. The most obvious and technically complicated features are metabolism and consciousness.
B. Growth and reproduction are mutually inclusive events for euglenoids and chrysophytes.
C. Generally, families and orders are identified on the basis of aggregates of vegetative characters only.
D. Herbarium serves as quick referral system in taxonomical studies.

A
B, C & D

B
A, C & D

C
B & D

D
A, B, & D
Solution
- Metabolism and consciousness are the most basic features as they are present even in the simplest of the organisms.
- Euglenoids and Chrysophytes are unicellular organisms. In unicellular organisms, reproduction and growth are mutually inclusive as both of them are accomplished through cell division.
- Families and orders do not have very specific characteristics for grouping and simple vegetative as well as floral or reproductive characters are considered for grouping.
- Herbariums have a collection of preserved plant specimens and information about them. They are quick and easy referrals for taxonomical studies.
So the correct answer is ' A, B & D'
Question 4
1 / -0

Select the group that shares maximum number of common characteristics.

A
2 individuals of species

B
2 species of genus

C
2 genera of a family

D
2 genera of 2 families
Solution
- As we move from higher taxonomic rank to lower one, common characters increase.
- Among species, genus, family and families; species is the lowest taxonomic rank. Hence, two individuals of the same species will share maximum number of common characters.
- So, the correct option is '2 individuals of species'.
Question 5
1 / -0

Select correct statement

A
Tomato, dicots and plants represent same taxa at different levels

B
Species is genetically open system

C
A breed of tiger and lion is a fertile true species

D
Biological concept of species is based on reproductive isolation

Solution

According to the biological concept of species, "species are groups of interbreeding natural populations that are reproductively isolated from other such groups." Hence the Biological concept of species is based on reproductive isolation.
So, the correct answer is 'Biological concept of species is based on reproductive isolation'.
Question 6
1 / -0

The taxonomic aid that provides information for the identification of names of species found in an area is _______.

A
Monograph

B
Manual

C
Catalogue

D
Periodical
Solution
- Monograph is a complete global account of a taxon of any rank – family, genus, or species at a given time.
- Manual is useful in providing information for the identification of names of species found in an area.
- Catalogue is the books of libraries rich in botanical titles.
- Periodicals is a publication appearing usually at regular intervals.
So, the correct answer is (B).
Question 7
1 / -0

Rice, Cereals, monocots and plants represent

A
Different taxa at different level.

B
Same taxa of different category

C
Different category of same taxa

D
Same category for different taxa

Solution

In biology nomenclature a taxa is a group of one or more organisms representing particular features. Rice is a monocot plant belonging to cereals (grains). Therefore these four terms rice cereal, monocot and plant represents different taxa at different level.

Hence, the correct option is 'Different taxa at different level'.
Question 8
1 / -0

__________ involves cytological information and methods.

A
Karyotaxonomy and Phonetics

B
Cytotaxonomy and Numerical taxonomy

C
Chemotaxonomy and Cytotaxonomy

D
More than one option is correct includes usage of numerical

Solution

The classification of organisms based on similarities and differences in the biochemical composition of cells. Cytotaxonomy deals with the classification and relationships of organisms using detail studies of chromosomes. Both of the classification systems involves the use of cytological ( cellular ) information.
So, the correct option is 'Chemotaxonomy and Cytotaxonomy'.
Question 9
1 / -0

A taxon is:

A
A group of related families

B
A group of related species

C
A type of living organisms

D
A taxomomic group of any ranking
Solution
- A taxon is a taxonomic group of any rank.
- The term taxon is a collection of more than one population of the organisms or organism seen by the taxonomists for forming a unit.
- There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species.
So, the correct option is 'A taxonomic group of any ranking'.
Question 10
1 / -0

Select the group of taxons representing same category of taxonomic hierarchy.

A
sativum, tuberosum, indica

B
Solanum, nilotica, Brassica

C
Potato, tomato, Legumes

D
Petunia, Datura, Solanaceae

Solution

A species is a taxonomic group or category that included all the interbreeding organisms of a population. Here, sativum, tuberosum, and indica all represent species of different plants. Hence, they represent the same taxonomic group.
So, the correct answer is 'sativum, tuberosum, indica'
