Biological organisation starts with
- A.
Cellular level
- B.
Organismic level
- C.
Atomic level
- D.
Submicroscopic molecular level
Correct Answer
D. Submicroscopic molecular levelExplanation
Biological organization refers to the hierarchical arrangement of biological structures, from the smallest components to the largest. The submicroscopic molecular level refers to the organization of biological entities at the molecular level, such as atoms, molecules, and macromolecules. This level of organization is the starting point because it forms the basis for the higher levels of organization. At this level, various biomolecules interact and combine to form more complex structures, such as cells, tissues, organs, and organisms. Therefore, the submicroscopic molecular level is the foundation upon which all other levels of biological organization are built.Rate this question:

Organisms which obtain energy by the oxidation of reduced inorganic compounds are called
- A.
Photoautotrophs
- B.
Chemoautotrophs
- C.
Saprozoic
- D.
Coproheterotrophs
Correct Answer
B. ChemoautotrophsExplanation
Chemoautotrophs are organisms that obtain energy by oxidizing reduced inorganic compounds. These compounds can include minerals such as iron or sulfur. Unlike photoautotrophs, which obtain energy from sunlight, chemoautotrophs rely on chemical reactions to produce energy. They are able to convert inorganic compounds into organic molecules, which they use as a source of energy. This adaptation allows chemoautotrophs to survive in environments where sunlight is not available, such as deep-sea hydrothermal vents or underground caves.Rate this question:

First life on earth was
- A.
Cyanobacteria
- B.
Chemoheterotrophs
- C.
Autotrophs
- D.
Photoautotrophs
Correct Answer
B. ChemoheterotrophsExplanation
Chemoheterotrophs are organisms that obtain energy by breaking down organic compounds through chemical reactions. They are unable to produce their own food and rely on consuming other organisms or organic matter for energy. The first life on Earth is believed to have been chemoheterotrophs, as they would have existed before the development of photosynthesis and the ability to produce food through sunlight. This explanation suggests that the first life forms on Earth obtained their energy by breaking down organic compounds in their environment.Rate this question:

Study of fossils is
- A.
Palaeontology
- B.
Herpetology
- C.
Saurology
- D.
Organic evolution
Correct Answer
A. PalaeontologyExplanation
Palaeontology is the study of fossils, including their formation, identification, and interpretation. It involves examining the remains of ancient organisms to understand their evolution, behavior, and the environment in which they lived. This field of science helps us reconstruct the history of life on Earth and provides valuable insights into the processes of organic evolution. Herpetology is the study of reptiles and amphibians, Saurology is not a recognized scientific term, and organic evolution is a broader concept that encompasses the study of fossils but also includes other aspects of evolutionary biology.Rate this question:

Employment of hereditary principles in the improvement of human race is
- A.
Euthenics
- B.
Eugenics
- C.
Euphenics
- D.
Ethnology
Correct Answer
B. EugenicsExplanation
Eugenics refers to the employment of hereditary principles in the improvement of the human race. It involves controlling and selecting the breeding of individuals with desirable traits in order to enhance the genetic quality of future generations. This concept gained popularity in the early 20th century but has since been widely criticized due to its association with unethical practices such as forced sterilization and discrimination based on race or disability.Rate this question:

Static concept of species was put forward by
- A.
De Candolle
- B.
Linnaeus
- C.
Theophrastus
- D.
Darwin
Correct Answer
B. LinnaeusExplanation
Linnaeus is the correct answer because he is known for developing the static concept of species. Linnaeus was a Swedish botanist who introduced the binomial nomenclature system for naming and classifying organisms. He believed that species were fixed and unchanging, and he classified them based on their physical characteristics. This concept of species as static entities remained influential for many years until it was challenged by the theory of evolution proposed by Darwin.Rate this question:

What is true for individuals of same species?
- A.
Live in same niche
- B.
Live in same habitat
- C.
Interbreeding
- D.
Live in different habitat
Correct Answer
C. InterbreedingExplanation
Individuals of the same species are able to interbreed with one another. This means that they can mate and produce offspring that are also capable of reproducing. Interbreeding is a defining characteristic of a species and helps to maintain genetic diversity within a population. It allows for the exchange of genetic material and can lead to the development of new traits and adaptations over time.Rate this question:

A taxon is
- A.
A group of related families
- B.
A group of related species
- C.
A type of living organisms
- D.
A taxonomic group of any ranking
Correct Answer
D. A taxonomic group of any rankingExplanation
The correct answer is "A taxonomic group of any ranking." This means that a taxon can refer to any level or rank in the classification system, such as a kingdom, phylum, class, order, family, genus, or species. It is a way to categorize and organize living organisms based on their evolutionary relationships and shared characteristics.Rate this question:

Binomial nomenclature was introduced by
- A.
De Vries
- B.
Carlous Linnaeus
- C.
Huxley
- D.
John Ray
Correct Answer
B. Carlous LinnaeusExplanation
Carlous Linnaeus is the correct answer because he is credited with introducing binomial nomenclature, which is the system of naming species using two Latin words - the genus name and the species name. Linnaeus developed this system in the 18th century and it is still widely used in modern taxonomy.Rate this question:

Binomial nomenclature consists of two words
- A.
Genus and Species
- B.
Order and Family
- C.
Family and Genus
- D.
Species and Variety
Correct Answer
A. Genus and SpeciesExplanation
Binomial nomenclature is a system used in biology to give each species a unique scientific name. It consists of two words: the genus and the species. The genus refers to a group of closely related species, while the species refers to a specific organism within that genus. This naming system helps scientists to categorize and identify different species accurately and universally.Rate this question:
