Question

multiple answer 2 points
which of the following statements about the classification of organisms are correct? select two.
organisms that are in the same family are more closely related than organisms of the same species.
classification is a system that only applies to plants and animals.
orders have a two - part name using the linnaean classification.
common characteristics and genetic information can be used to classify an unknown organism.
classification is important for sorting both living and extinct organisms.

Explanation:

• Option 1: Species is a more specific category than family. Organisms of the same species are more closely related than those in the same family. So this option is incorrect.
• Option 2: Classification applies to all living organisms (including bacteria, fungi etc.), not just plants and animals. So this option is incorrect.
• Option 3: Binomial nomenclature (two - part name) is for species (e.g., Homo sapiens), not orders. So this option is incorrect.
• Option 4: Taxonomists use common characteristics (morphological, physiological) and genetic information (e.g., DNA sequencing) to classify unknown organisms. This is correct.
• Option 5: Classification helps in organizing and understanding the diversity of life. It is used for both living (e.g., currently existing species) and extinct (e.g., fossil species) organisms. This is correct.

Answer:

• Fourth option: Common characteristics and genetic information can be used to classify an unknown organism.
• Fifth option: Classification is important for sorting both living and extinct organisms.
