Shilpa Bose answered |
Less General than Genus: Species
Explanation:
- Genus is a taxonomic rank used in the biological classification of living and fossil organisms.
- It is a more general category than species, which is the basic unit of classification and the lowest taxonomic rank.
- Species is less general than genus because it refers to a specific group of organisms that share common characteristics and can interbreed to produce fertile offspring.
- Family, class, and division are all higher taxonomic ranks than species and therefore more general in nature.

Shalini Khanna answered |
Genera
- Solanum, Panthera, Homo are examples of the scientific classification category called genera.
- Genera is a taxonomic rank used in the biological classification of living and fossil organisms.
- It is the second-lowest rank, just above species, in the hierarchical classification system.
- Genera are groups of closely related species that share a common ancestor and have similar physical characteristics, such as morphology, anatomy, and genetics.
- Each genus is given a unique name, which is written in italics and capitalized.
- The first letter of the genus name is always capitalized, while the species name is written in lowercase.
- The name of the genus is followed by the name of the species, which is called the species epithet or specific epithet.
- The combination of genus and species names is known as the binomial nomenclature, which is used to identify and distinguish each species from others.

Shreya Menon answered |
Explanation:
In the context of biological names, statement 3 is incorrect. When handwritten, biological names are typically underlined, not separately, but as a whole to indicate their vernacular origin. When printed, biological names are usually written in italics. Underlining individual words in a biological name is not a standard practice.
The correct practice is to underline the entire biological name when handwritten or italicize it when printed.
Therefore, the correct answer is 3. Both the words in a biological name, when handwritten, are not separately underlined, or printed in italics to indicate their vernacular origin.

Pooja Mehta answered |
Plants and animals share many characteristics, but they are different in some respects. Animals usually move around and find their own food, while plants are usually immobile and create their food via photosynthesis. Plants and animals both have cells that contain DNA, yet the structure of their cells differs. Animal cells absorb nutrients from food, while plant cells use plastids to create energy from sunlight.

Poulomi Roy answered |
Botanical gardens and zoological parks are places where people can go to observe and learn about different species of plants and animals. These places have a collection of different living species. Let's discuss the answer option by option:
a) Collection of endemic living species only:
- Endemic species are those that are native to a particular region or habitat.
- If a botanical garden or zoological park had a collection of only endemic species, it would mean that they only have plants and animals that are found naturally in that specific area.
- This would limit the diversity of the collection and make it less interesting for visitors.
b) Collection of exotic living species only:
- Exotic species are those that are not native to a particular region or habitat.
- If a botanical garden or zoological park had a collection of only exotic species, it would mean that they only have plants and animals that are not found naturally in that specific area.
- This may make the collection more interesting for visitors, but it would not showcase the biodiversity of the local area.
c) Collection of endemic and exotic living species:
- Having a collection of both endemic and exotic species allows for a greater diversity of plants and animals for visitors to observe and learn about.
- This also allows for a comparison between the local species and those from other regions, highlighting the uniqueness of each species.
d) Collection of only local plants and animals:
- Having a collection of only local plants and animals can be educational for visitors, as they can learn about the biodiversity of the local area.
- However, it may not be as interesting for visitors who are looking for a wider variety of plants and animals to observe and learn about.
In conclusion, the correct answer is option C, as having a collection of both endemic and exotic living species provides visitors with a diverse and interesting experience, while also highlighting the uniqueness of each species.

Taxon Family and its Ending
A taxon family is a group of related organisms within a classification system. The ending of a taxon family is determined by the International Code of Nomenclature for algae, fungi, and plants (ICN) and International Code of Zoological Nomenclature (ICZN). The ending of a taxon family reflects the rank of the taxon within the classification system.
- The ending "-ales" is used for the order level in the ICN classification system. For example, the order of flowering plants, Rosales.
- The ending "-ae" is used for the class level in the ICN classification system. For example, the class of flowering plants, Magnoliopsida.
- The ending "-ceae" is used for the family level in the ICN classification system. For example, the family of flowering plants, Rosaceae.
- In the ICZN classification system, the ending "-idae" is used for the family level. For example, the family of cats, Felidae.
Therefore, the correct answer to the given question is option C, "-ceae" is the ending of a taxon family in the ICN classification system.

Prashanth Menon answered |
Taxon is a term used in biological classification and refers to a taxonomic group of any ranking. It is used to classify living organisms into categories based on their characteristics, evolutionary history, and relationships to other organisms. Taxonomy is the science of naming, describing, and classifying organisms based on their characteristics and evolutionary relationships.
Types of Taxonomic Ranks
Taxonomic ranks are hierarchical levels of classification used to group organisms based on their characteristics, evolutionary history, and relationships to other organisms. The different types of taxonomic ranks are:
1. Domain
2. Kingdom
3. Phylum
4. Class
5. Order
6. Family
7. Genus
8. Species
Each rank is divided into smaller subcategories, providing a systematic framework for organizing and categorizing the diversity of life on Earth.
Importance of Taxonomy
Taxonomy is important because it helps scientists understand the diversity of life on Earth, how organisms are related to each other, and how they have evolved over time. It provides a way to organize and classify organisms into groups based on their characteristics and evolutionary relationships.
Taxonomy also helps scientists identify and name new species, and it provides a standardized system for communicating information about organisms. This is important for conservation efforts, as it allows researchers to identify and protect endangered species and ecosystems.
Conclusion
In conclusion, a taxon is a taxonomic group of any ranking used to classify living organisms based on their characteristics, evolutionary history, and relationships to other organisms.

Debolina Chopra answered |
The Correct Answer is Option D: Mangifera indica Linn.
Explanation:
Scientific names of organisms are used universally to avoid confusion due to differences in common names across different regions and languages. They follow a specific format called the binomial nomenclature, developed by Carolus Linnaeus in the 18th century.
In the binomial nomenclature, the scientific name of an organism consists of two parts - the genus name (first word) and the species name (second word) - both written in italics. The genus name is always capitalized, while the species name is in lowercase. The author's name who first described the species is written after the species name, abbreviated and also capitalized.
Mango was first described by Carolus Linnaeus, the father of modern taxonomy. He gave it the scientific name Mangifera indica.
Now let's look at the given options:
a) Mangifera indica - This is the correct scientific name of Mango, with the correct formatting of the genus name, species name, and author's name.
b) Mangifera indica Car. Linn. - This is incorrect because the author's name is not abbreviated correctly. The correct abbreviation for Carolus Linnaeus is "L.", not "Linn.".
c) Mangifera Indica Lin - This is incorrect because the genus name is not capitalized, and the author's name is not abbreviated correctly.
d) Mangifera indica Linn - This is the correct scientific name of Mango, with the correct formatting of the genus name, species name, and author's name.
Therefore, option D is the correct answer.

The correct answer is option 'B', which is a manual.
Explanation:
A manual is a book that contains instructions or information about a particular subject. In this case, the manual is a handy book that provides instructions for the occurrence, collection, and identification of species found in a particular area.
Key, Flora, and Monograph are also related to identifying species, but they have different meanings:
- A Key is a tool used to identify an unknown species by answering a series of yes or no questions.
- Flora is a comprehensive listing of all plant species found in a particular area.
- Monograph is a detailed written study of a particular group of organisms, often focusing on their taxonomy, distribution, and characteristics.
Therefore, the best answer for a book containing instructions for the occurrence, collection, and identification of species found in a particular area is a manual.

Taxonomy is the practice of identifying different organisms, classifying them into categories and naming them.
So, the first step in taxonomy would be identification.
We would first identify the organisms, classify them, note down their characteristics and then give the scientific names.
So, the correct order would be-
- Identification
- Classification
- Characterization
- Nomenclature
A taxon is- a)A type of living organism

1. Biological Species Concept: Mayr introduced the Biological Species Concept which defined a species as a group of individuals that can interbreed and produce viable offspring. This concept is widely accepted in the field of evolutionary biology.
2. Evolutionary Synthesis: Mayr played a crucial role in the development of the Evolutionary Synthesis, which was a unification of genetics and evolutionary biology. He proposed that the evolution of new species occurred due to the accumulation of genetic changes over time.
3. Geographic Speciation: Mayr proposed the theory of geographic speciation, which suggests that the formation of new species occurs when a population is geographically isolated from the parent population.
4. Ornithology: Mayr was also an accomplished ornithologist and contributed significantly to the study of bird species. He proposed the theory of allopatric speciation in birds, which suggests that the formation of new bird species occurs due to geographic isolation.
5. Systematics: Mayr made significant contributions to the field of systematics, which is the study of the classification of living organisms. He proposed the concept of "cladistics", which is a method of classification that groups organisms based on their evolutionary history.
Conclusion:
Ernst Mayr's contributions to the field of evolutionary biology have had a significant impact on our understanding of the process of evolution. His work has helped to shape the field of evolutionary biology and has influenced generations of biologists. Therefore, it is justified to consider him as the "Darwin of 20th century".

Sahil Basu answered |
Primate and Carnivora are placed together in the same Class.
Explanation:
Primates and Carnivora belong to the same Class, Mammalia, which is one of the five major classes of animals. The Class Mammalia is characterized by the presence of mammary glands, hair or fur, and three middle ear bones.
Primates are a group of mammals that includes monkeys, apes, and humans. They are characterized by their opposable thumbs, forward-facing eyes, and complex social behavior. Primates are divided into two suborders: Strepsirrhines (lemurs, lorises, and galagos) and Haplorhines (tarsiers, monkeys, apes, and humans).
Carnivora is a diverse group of mammals that includes carnivorous animals such as cats, dogs, bears, and weasels. They are characterized by their sharp teeth and claws, and their ability to catch and kill prey. Carnivores are divided into two suborders: Caniformia (dogs, bears, weasels, and raccoons) and Feliformia (cats, hyenas, and civets).
Both Primate and Carnivora belong to the same Class because they share some common characteristics like mammary glands, hair or fur, and three middle ear bones. However, they differ in many other characteristics like diet, behavior, and anatomy.

The ICZN is designed to ensure that each species has a unique, stable, and recognizable name that is widely accepted by the scientific community. It provides guidelines for the creation, spelling, and use of scientific names, as well as rules for resolving conflicts when different names are proposed for the same species.
The ICZN is maintained by the International Commission on Zoological Nomenclature (ICZN), which is responsible for interpreting and enforcing the rules of the code. The ICZN is recognized as the official code of nomenclature for animals by most countries and scientific organizations around the world.
In summary, the ICZN is an internationally recognized set of rules and guidelines for the naming of animals, designed to ensure that each species has a unique and stable name that is widely accepted by the scientific community.

Anshika Mishra answered |
The Basic Unit of Classification:
The basic unit of classification is the species.
Explanation:
Species is the fundamental unit of classification in biology. It is defined as a group of individuals that can interbreed and produce fertile offspring.
Other taxonomic units such as genus, family, phylum, etc. are based on various characteristics of the organisms, but they all ultimately boil down to the species level.
Here are some of the reasons why species is considered the basic unit of classification:
1. Reproductive isolation: Members of the same species can interbreed and produce viable offspring, whereas members of different species cannot. This reproductive isolation is a crucial criterion for defining a species.
2. Evolutionary lineage: Species are also defined based on their evolutionary history and relationships. Organisms that share a common ancestor are grouped together into a species, and those that diverged earlier or later are classified into different species.
3. Practicality: The species level is also a practical unit of classification because it is often easier to identify and study individual organisms than larger groups.
In summary, the species is the basic unit of classification in biology because it represents a group of individuals that can interbreed and share a common evolutionary history.

The 8 levels of modern taxonomy classification systems are Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
Classification involves hierarchy of steps in which each step represents taxonomic category. Each taxonomic category is referred to as a unit of classification and is commonly termed as taxon. Taxonomic hierarchy is a system of arranging all taxonomic categories in descending order with kingdom at the top and species at the base.
As we go up the taxonomical hierarchy, the number of individuals.' increases but the number of common characteristics goes on decreasing.

Dev Patel answered |
If two organisms are in the same phylum, they must also be in the same higher taxonomic category, which is the kingdom.They do not necessarily belong to the same class, order, or species, because those categories are more specific and fall under the phylum category.
Therefore, the correct answer is: kingdom

Aristotle is known as the 'Father of Biology'. Again, Botany and Zoology combine to form biology. So, I think Aristotle can e regarded as the "Father of Zoology'' as well as the "Father of Botany".

To understand the concept of genus in taxonomy:
- A genus typically comprises a group of species sharing more common characteristics among themselves than with species from other genera.
- This distinction helps in classifying organisms into related groups based on similarities in traits.
- Therefore, the correct answer is B: "More common character possessing group of species than species of other genera." This choice highlights the defining feature of a genus in taxonomy.
