1.
Biological organisation starts with
Correct Answer
D. Submicroscopic molecular level
Explanation
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.
2.
Organisms which obtain energy by the oxidation of reduced inorganic compounds are called
Correct Answer
B. ChemoautotropHs
Explanation
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.
3.
First life on earth was
Correct Answer
B. ChemoheterotropHs
Explanation
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.
4.
The book Genera Plantarum was written by
Correct Answer
D. Bentham & Hooker
Explanation
The book Genera Plantarum was written by Bentham & Hooker.
5.
Study of fossils is
Correct Answer
A. Palaeontology
Explanation
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.
6.
Employment of hereditary principles in the improvement of human race is
Correct Answer
B. Eugenics
Explanation
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.
7.
Static concept of species was put forward by
Correct Answer
B. Linnaeus
Explanation
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.
8.
What is true for individuals of same species?
Correct Answer
C. Interbreeding
Explanation
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.
9.
A taxon is
Correct Answer
D. A taxonomic group of any ranking
Explanation
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.
10.
Binomial nomenclature was introduced by
Correct Answer
B. Carlous Linnaeus
Explanation
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.
11.
Binomial nomenclature consists of two words
Correct Answer
A. Genus and Species
Explanation
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.
12.
The term phylum was given by
Correct Answer
A. Cuvier
Explanation
Cuvier is credited with giving the term "phylum." He was a French naturalist and zoologist who made significant contributions to the field of comparative anatomy. Cuvier is known for his work in classifying and categorizing animals, and he introduced the concept of phylum as a way to group organisms based on their anatomical characteristics. This term has since become a fundamental concept in the field of biology and is used to classify and organize the animal kingdom.
13.
Linnaeus evolved a system of nomenclature called
Correct Answer
C. Binomial
Explanation
Linnaeus evolved a system of nomenclature called binomial. This system involves giving each species a unique two-part scientific name consisting of the genus and species. It is a standardized way to classify and name organisms, allowing scientists to communicate effectively and avoid confusion. The binomial nomenclature system is widely used in biology and is still in use today.
14.
Basic unit or smallest taxon of taxonomy classification is
Correct Answer
A. Species
Explanation
The basic unit or smallest taxon of taxonomy classification is the species. In taxonomy, species is the fundamental category that groups together organisms with similar characteristics and can interbreed to produce fertile offspring. It is a crucial concept in understanding the diversity and classification of living organisms.
15.
The term "New Systematics' was introduced by
Correct Answer
C. Julian Huxley
Explanation
Julian Huxley is the correct answer because he is credited with introducing the term "New Systematics." Huxley was a renowned biologist and evolutionary theorist who played a significant role in advancing the field of systematics. He emphasized the importance of incorporating evolutionary principles and genetics into the classification and understanding of organisms, which led to the development of the "New Systematics" approach. This approach revolutionized the study of taxonomy and laid the foundation for modern evolutionary biology.
