1. In taxonomy, a species is defined as a group of organisms having:
Correct Answer: B
In taxonomic studies, a species is considered a group of individual organisms that share fundamental similarities. These organisms resemble each other closely and can reproduce among themselves, forming a basic unit of classification.
2. Closely related species are mainly distinguished based on:
Correct Answer: B
Closely related species may appear similar, but they can be distinguished based on clear morphological differences. Morphological characters include structure, shape, and physical features of organisms. These differences help scientists identify and separate one species from another.
3. In the scientific names Mangifera indica, Solanum tuberosum, and Panthera leo, the words 'indica', 'tuberosum', and 'leo' represent:
Correct Answer: C
In binomial nomenclature, each scientific name has two parts. The first word represents the genus, such as Mangifera, Solanum, and Panthera. The second word represents the specific epithet, such as indica, tuberosum, and leo, which identifies the species within that genus.
4. In taxonomy, a genus may contain:
Correct Answer: B
A genus is a taxonomic category that can include one or more species. Each species within the genus has a different specific epithet, but they share several common characteristics that justify grouping them under the same genus.
5. Each genus may have one or more specific epithets representing different organisms, but having ______ similarities.
Correct Answer: B
Species belonging to the same genus may have different specific epithets, but they share important morphological similarities. These similarities in structure and form help taxonomists group them under the same genus.
6. The example Panthera leo (lion) and Panthera tigris (tiger) shows that:
Correct Answer: A
In biological classification, a genus can include more than one species that share similar morphological characteristics. For example, the genus Panthera includes species such as Panthera leo (lion) and Panthera tigris (tiger).
7. The examples Solanum tuberosum (potato), Solanum nigrum, and Solanum melongena show that:
Correct Answer: A
In biological classification, a genus may include more than one species that share similar morphological characteristics. For example, the genus Solanum includes species such as Solanum tuberosum (potato), Solanum nigrum (black nightshade), and Solanum melongena (brinjal).
8. Humans belong to the species ______ and genus ______.
Correct Answer: A
Human beings are scientifically named Homo sapiens. In this binomial name, 'Homo' represents the genus and 'sapiens' represents the species. Therefore, humans belong to the species sapiens and the genus Homo.
9. What is the scientific name of human beings?
Correct Answer: A
The scientific name of human beings is Homo sapiens. In this binomial name, 'Homo' represents the genus and 'sapiens' represents the species. This two-word naming system is called binomial nomenclature.
10. A genus is defined as:
Correct Answer: B
A genus is a taxonomic category that includes a group of closely related species. These species share more common characteristics with each other than with species belonging to other genera. Therefore, genus represents a higher taxonomic rank above species.
11. Genera are best described as:
Correct Answer: A
A genus consists of closely related species that share several similar characteristics. Because it groups together such similar species, a genus is described as an aggregate of closely related species.
12. Potato and brinjal belong to the same genus:
Correct Answer: C
Potato (Solanum tuberosum) and brinjal (Solanum melongena) are two different species, but both belong to the same genus Solanum. This shows that a genus can include multiple closely related species.
13. Lion (Panthera leo), leopard (P. pardus), and tiger (P. tigris) belong to the genus:
Correct Answer: B
Lion (Panthera leo), leopard (Panthera pardus), and tiger (Panthera tigris) share several common characteristics and therefore belong to the same genus Panthera. A genus groups together closely related species.
14. The genus Panthera differs from which genus that includes cats?
Correct Answer: B
Lion (Panthera leo), leopard (Panthera pardus), and tiger (Panthera tigris) belong to the genus Panthera. This genus is different from another genus called Felis, which includes cats. Different genera group species with different sets of characteristics.
