The common characteristics between tomato and potato will be maximum at the level of their: 
Which one of the following is NOT a correct statement? [NEET 2013]
Which one of the following organisms is scientifically correctly named, correctly printed according to the International Rules of Nomenclature and correctly described? [2012M]
Which one of the following aspects is an exclusive characteristic of living things? [2011M]
Consciousness is the exclusive characteristic of living organisms as only living organisms are aware of their surroundings.
Which one of the following is considered important in the development of seed habit? 
The haemoglobin of a human foetus: 
Select the CORRECT statement from the following? 
To survive in a particular environment, an organism need to adapt to that environment. If the organism becomes a success in adapting them that organism is selected by nature.
The biological organisation starts with: 
Which of the following is NOT true for a species? 
Angiosperms have dominated the land flora primarily because of their: 
Phenetic classification is based on: [2003, 04]
Phenetic classification is based upon observable characteristics of an organism. Phylogenetic system of classification is a system indicating the evolutionary or phylogenetic relationship of organisms.
Plants reproducing by spores such as mosses and ferns are grouped under the general term: 
Species are considered as: 
Biosystematics aims at: 
Organisms that obtain energy by the oxidation of reduced inorganic compounds are called: 
What is TRUE for individuals of the same species? 
Individuals of the same species can interbreed. No two individuals share the same ecological niche.
In a five-kingdom system, the main basis of classification is: 
The five-kingdom classification is a mode of classification based on the following criteria:
First life on earth was: 
Early conditions on earth were high temperature, volcanic eruptions, lightning and a reducing atmosphere (because there was no oxygen), so an organism that can survive in these extreme conditions might have lived on the early earth. Therefore, among given options, chemoheterotrophs fit right in the given situations.
What is TRUE for photolithotrophs? 
Photolithotrophs manufacture their own organic nutrients from inorganic raw materials (H2, O2) with the help of radiation energy.
Which of the following is less general in characters as compared to genus? 
The correct hierarchy of classification of various taxons in descending order is given by:
Kingdom → Phylum → Class → Order → Family → Genus → Species
The kingdom is the highest taxon with the least similar characters shared between its various members while the species is the lowest level with almost similar morphological and behavioural similarities. Species is followed by Genus with slightly fewer similarities among its members.
Relative biological effectiveness (RBE) is usually referred to as damages caused by: 
RBE (Relative Biological Effectiveness) is a comparison of the dose of the radiation being studied with the dose of standard radiation producing the same effect.
The most important feature of all living systems is to: 
A system of classification in which a large number of traits are considered is: 
The practical purpose of the classification of living organisms is to: 
System of classification used by Linnaeus was: 
Linnaeus put forward an “Artificial system” of plant classification which was based on sexual characters. It is commonly also called as Sexual System of plant classification.
