Question 1: Briefly explain the main principle behind the Linnaean System of classification.

Answer: The Linnaean System classifies organisms based on hierarchical categories such as kingdom, phylum, class, order, family, genus, and species, using binomial nomenclature.

Question 2: What is the significance of binomial nomenclature in the Linnaean System?

Answer: Binomial nomenclature gives each species a two-part Latin name, consisting of the genus and species, ensuring universal recognition and avoiding confusion.

Question 1: Define 'taxon' in the context of biological classification.

Answer: A taxon is a group of one or more organisms classified as a unit, such as a species, genus, or family.

Question 2: List the seven hierarchical levels used in the Linnaean System from broadest to most specific.

Answer: Kingdom, Phylum, Class, Order, Family, Genus, Species

Question 3: Explain why the Linnaean System is considered a hierarchical classification.

Answer: Because organisms are grouped into nested categories, with each level representing a different degree of relatedness, from broad to specific.

Question 1: If the total number of species in a genus is 150, and the genus belongs to a family with 10 genera, what is the average number of species per genus in that family? Show your calculation.

Answer: Average species per genus = Total species in family / Number of genera = 150 / 10 = 15 species

Question 2: Calculate the total number of species if a genus has 20 species and contains 8 such genera.

Answer: Total species = Number of species per genus × Number of genera = 20 × 8 = 160 species

Question 1: Describe a basic experiment to classify a new organism using the Linnaean System. Include the variables involved and safety precautions.

Answer: To classify a new organism, observe its physical features, compare with known taxa, and determine its genus and species. Variables include morphological traits, habitat, and genetic markers. Precautions involve wearing gloves, handling specimens carefully, and sterilizing equipment to prevent contamination.

Question 1: A researcher classifies 200 organisms into 5 families, with the following number of species: Family A - 50, Family B - 40, Family C - 60, Family D - 30, Family E - 20. Calculate the average number of species per family and identify which family has the highest diversity.

Answer: Average species per family = Total species / Number of families = 200 / 5 = 40 species. Family C has the highest diversity with 60 species.

Question 1: Explain how the Linnaean System helps scientists communicate about species and why it is important in modern biology. Provide examples of its application in industry or technology.

Answer: The Linnaean System provides a standardized way to name and categorize organisms, facilitating clear communication among scientists worldwide. It helps in biodiversity conservation, agriculture, medicine, and biotechnology by accurately identifying species. For example, the classification of genetically modified crops or identifying disease-causing bacteria relies on this system.
