Q1NEET 2021
Which one of the following belongs to the family Muscidae ?
Not quite — the answer is D.
The housefly, Musca domestica, belongs to the family Muscidae of order Diptera. Grasshopper and cockroach belong to other insect orders and the firefly is a beetle.
Q2NEET 2019 · Q144
Select the correctly written scientific name of Mango which was first described by Carolus Linnaeus :
Not quite — the answer is B.
The binomial is written with a capital genus and small-letter specific epithet, followed by the abbreviated author name 'Linn.' when Linnaeus described it. Capitalising 'Indica' breaks the rule, and leaving out the author does not show who first described it.
Q3NEET 2017 (Gujarati paper) · Q73
Given below are defined the various taxonomic aids used in taxonomy which facilitate identification and classification of organisms. Which one of the following is wrong?
Not quite — the answer is A.
A herbarium stores dried, pressed and preserved plant specimens mounted on sheets, not live plants; living plants are kept in botanical gardens. The statements on museums, botanical gardens and zoos, and keys and floras are correct.
Q4NEET 2016 Phase 2 · Q94
The label of a herbarium sheet does not carry information on
Not quite — the answer is D.
A herbarium label records the date and place of collection, the collector's name, and the botanical, family and local names of the specimen. The height of the plant is not a standard entry on the label, since the pressed specimen itself is kept on the sheet.
Q5NEET 2016 Phase 2 · Q137
Match Column-I with Column-II for housefly classification and select the correct option using the codes given below: Column-I: a. Family; b. Order; c. Class; d. Phylum Column-II: (i) Diptera; (ii) Arthropoda; (iii) Muscidae; (iv) Insecta
Not quite — the answer is A.
The housefly Musca domestica belongs to family Muscidae, order Diptera, class Insecta and phylum Arthropoda. Only one code pairs family with Muscidae, order with Diptera, class with Insecta and phylum with Arthropoda.
Q6NEET 2016 Phase 2 · Q139
Study the four statements (A–D) given below and select the two correct ones out of them: A. Definition of biological species was given by Ernst Mayr. B. Photoperiod does not affect reproduction in plants. C. Binomial nomenclature system was given by R. H. Whittaker. D. In unicellular organisms, reproduction is synonymous with growth. The two correct statements are
Not quite — the answer is C.
Ernst Mayr gave the biological species concept, and in unicellular organisms division of the cell is both growth and reproduction, so A and D are correct. Photoperiod does affect flowering and reproduction, and binomial nomenclature was given by Linnaeus, while Whittaker proposed the five-kingdom system.
Q7NEET 2016 Phase 1 · Q160
Nomenclature is governed by certain universal rules. Which one of the following is contrary to the rules of nomenclature?
Not quite — the answer is A.
Scientific names must be in Latin or Latinised form, so writing them in any language is against the rules. Binomials consist of genus followed by specific epithet, printed in italics or underlined separately when handwritten.
Q8AIPMT 2012 Mains
Which one of the following organisms is scientifically correctly named, correctly printed according to the International Rules of Nomenclature and correctly described?
Not quite — the answer is B.
Plasmodium falciparum is correctly named and causes malignant malaria, the most serious kind. Musca domestica is the housefly, the tiger is Panthera tigris and Gir protects lions, and E. coli stands for Escherichia coli, not Entamoeba.
Q9AIPMT 2011 Mains
Which one of the following aspects is an exclusive characteristic of living things?
Not quite — the answer is A.
Consciousness, the ability to sense the environment and remember it, is the defining property found only in living things. Increase in mass by surface accumulation also occurs in non-living things such as crystals and mountains, and isolated metabolic reactions in vitro are not living.
Q10AIPMT 2011 Prelims
Which one of the following organisms is not an example of eukaryotic cells
Not quite — the answer is C.
Escherichia coli is a bacterium and so has a prokaryotic cell without a nuclear membrane. Amoeba, Paramecium and Euglena are protists with true nuclei, so they are eukaryotes.
Q11AIPMT 2011 Prelims
Which one of the following animals is correctly matched with its particular named taxonomic category?
Not quite — the answer is B.
In Panthera tigris, the tiger, 'tigris' is the specific epithet that denotes the species. Musca is the genus of the housefly, Mollusca is a phylum, and Primata is an order, not a family.
Q12AIPMT 2007 Prelims · Q101
ICBN stands for
Not quite — the answer is A.
ICBN is the International Code of Botanical Nomenclature, the internationally agreed set of rules for giving scientific names to plants. It is an international code, not an Indian one, and it deals with botanical names, not a congress on biological names.
Q13AIPMT 2007 Prelims · Q103
Biological organisation starts with
Not quite — the answer is D.
The levels of biological organisation begin with biomolecules at the submicroscopic molecular level, which then build organelles, cells, tissues and organisms. Atoms are the units of chemistry rather than of biological organisation, and the cell is a higher level built from those molecules.
Q14AIPMT 2007 Prelims · Q115
The living organisms can be unexceptionally distinguished from the non-living things on the basis of their ability for
Not quite — the answer is A.
NCERT points out that reproduction cannot be a defining property, since sterile organisms such as mules and worker bees do not reproduce, and growth is also seen in non-living things like crystals and mountains. Sensing and interacting with the environment (consciousness) together with the capacity to evolve is shown by every living organism, so it is the exceptionless distinction.
Q15AIPMT 2007 Prelims · Q160
Two plants can be conclusively said to belong to the same species if they
Not quite — the answer is D.
By the biological species concept, members of a species interbreed freely in nature and produce fertile offspring (here, viable seeds). Similar appearance, chromosome number or gene similarity can be shared by different species, so they are not conclusive.
